A design method was developed to specify the profile of the continuously variable Mach-number nozzle for the supersonic wind tunnel. The controllable contour design technique was applied to obtaining the original nozzle profile, while other Machnumbers were derived from the transformation of the original profile. A design scheme, covering a Mach-number range of3.0<Ma<4.0, was shown to illustrate the present design technique. To fully validate the present design method, computational fluid dynamics(CFD) analyses were carried out to study the flow quality in the test area of the nozzle. The computed results indicate that exit uniform flow is obtained with 1.19% of the maximal Mach-number deviation at the nozzle exit. The present design method achieves the continuously variable Mach-number flow during a wind tunnel running. 展开更多

The performance and composition of traditional choral music were championed and dominated by women. Unfortunately, the involvement of women in the practice of art music, specifically theory and composition in Ghana has been observed to be absent or very minimal, the cause of which is problematic to identify. This paper examines why women have been passive in the performance and composition of this musical genre, and suggests avenues for improvement in the situation. Fifteen women across various musical genres: Traditional, Art and Popular were interviewed to ascertain this fact. The results will serve as an aid for an improvement of this unfortunate situation in Ghana. 展开更多

Laboratory experiments and field observations show that the equilibrium range of wind wave spectra presents a – 4 power law when it is scaled properly. This feature has been attributed to energy balance in spectral space by many researchers. In this paper we point out that white noise on an oscillation system can also lead to a similar inverse power law in the corresponding displacement spectrum, implying that the – 4 power law for the equilibrium range of wind wave spectra may probably only reflect the randomicity of the wind waves rather than any other dynamical processes in physical space. This explanation may shed light on the mechanism of other physical processes with spectra also showing an inverse power law, such as isotropic turbulence, internal waves, etc. 展开更多

The aim of this paper is to analyze the album covers of English band Depeche Mode after 80's according to the principles of graphic design. Established in 1980, the musical style of the band was turned from synth-pop to new wave, from new wave to electronic, dance, and alternative-rock in decades, but their message stayed as it was: A non-hypocritical, humanist, and decent manner against what is wrong and in love sincerely. As a graphic design product, album covers are pre-print design solutions of two dimensional surfaces. Graphic design, as a design field, has its own elements and principles. Visual elements and typography are the two components which should unite with the help of the six main principles which are: unity/harmony; balance; hierarchy; scale/proportion; dominance/emphasis; and similarity and contrast. All album covers of Depeche Mode after 80's were designed in a simple but dominant way in order to form a unique style. On every album cover, there are huge color, size, tone, and location contrasts which concluded in simple domination; domination of a non-hypocritical, humanist, and decent manner against what is wrong and in love sincerely. 展开更多

This paper displays the results of a survey of public music performances held during 2010 in Skopje, the capital of the Republic of Macedonia. Study of the audience of public musical events was limited only to the number of visitors. Field research included 653 musical events with a total of 545,340 visitors grouped into eight categories according to the preference by genres of music preference, age, status symbol, origin of the performers, space, and organizers. Our experience in monitoring public musical events through personal presence, the recorded materials, and the continuous monitoring of information from electronic and print media, enabled us to record events and to build some initial comments and assumptions about the structure of the audience and music preference. We have chosen to consider the impact of the sociological determinants on the preference of the audience in the public musical performances through the music genres, the age, the status symbol, the origin of the performers, the area of maintenance, and the organizers of musical events. According to the genre distribution, classical music events prevail, and the greatest numbers of visitors are registered at the pop rock concerts. The structure of the audience according to the age varies depending on the musical genre, so the widest age structure covers the events of pop rock music. 展开更多

Thus, this paper describes a two-part study of tonal noise computation. The first part deals with the prediction of tonal noise using analytical models. As for the second part, it describes a hybrid approach for predicting tonal noise where the sources are extracted from an Unsteady Reynolds-Averaged Naviers-Stocks (URANS) simulation and then propagated into the far, free field using the Ffowcs Williams and Hawkings' acoustic analogy. The computational domain is meshed with 46 million polyhedral elements and the simulation takes into account the exact geometry of the rotor blades, the stator blades and the shroud. The results from the first part show that analytical models can be used for comparisons between different fan geometries, but are unable to provide accurate noise predictions compared to experimental results. The simulation shows non-periodic blade loading over a whole fan revolution, and different blade loading between the blades. This introduces some bias in the assessment of the acoustic performance of the fan. Overall, the results from the hybrid method are in accordance with the experimental results. 展开更多

In this study, comparative heat flux measurements for a sharp cone model were conducted by utilizing a high enthalpy shock tunnel JF-10 and a large-scale shock tunnel JF-12, responsible for providing nonequilibrium and perfect gas flows, respectively. Experiments were performed at the Key Laboratory of High Temperature Gas Dynamics(LHD), Institute of Mechanics, Chinese Academy of Sciences. Corresponding numerical simulations were also conducted in effort to better understand the phenomena accompanying in these experiments. By assessing the consistency and accuracy of all the data gathered during this study, a detailed comparison of sharp cone heat transfer under a totally different kind of freestream conditions was build and analyzed. One specific parameter, defined as the product of the Stanton number and the square root of the Reynold number, was found to be more characteristic for the aerodynamic heating phenomena encountered in hypersonic flight. Adequate use of said parameter practically eliminates the variability caused by the deferent flow conditions, regardless of whether the flow is in dissociation or the boundary condition is catalytic. Essentially, the parameter identified in this study reduces the amount of ground experimental data necessary and eases data extrapolation to flight. 展开更多

Some two-microphone noise reduction techniques that work in the frequency domain exploit coherence function between two noisy signals. They have shown good results when noise signals on two sensors are uncorrelated, but their per-formance decreases with correlated noises. Coherence based methods can be improved when the cross power spectral density (CPSD) of correlated noise signals is available. In this paper, we propose a new method for estimation of the CPSD of the noise, which is based on the minimum tracking technique. Despite the fact that the proposed estimator does not need to implement a voice activity detector (VAD), its performance is comparable to a CPSD estimator that uses an ideal VAD. 展开更多

In this study, a transonic flow past NACA0012 profile at angle of attack α=0^0 whose aspect ratio AR is 1.0 with non-equilibrium condensation is analyzed by numerical analysis using a TVD scheme and is investigated using an intermittent indraft type supersonic wind tunnel. Transonic flows of 0.78-0.90 in free stream Mach number with the variations of the stagnation relative humidity(φ0) are tested. For the same free stream Mach number, the increase in φ0 causes decrease in the drag coefficient of profile which is composed of the drag components of form, viscous and wave. In the case of the same Moo and To, for more than φ0=30%, despite the irreversibility of process in non-equilibrium condensation, the drag by shock wave decreases considerably with the increase of φ0. On the other hand, it shows that the effect of condensation on the drag coefficients of form and viscous is negligible. As an example, the decreasing rate in the drag coefficient of profile caused by the influence of non-equilibrium condensation for the case of M∞=0.9 and φ0 =50% amounts to 34%. Also, it were turned out that the size of supersonic bubble (that is, the maximum height of supersonic zone) and the deviation of pressure coefficient from the value for M=1 decrease with the increase of φ0 for the same M∞. 展开更多

Gust alleviation is very important to a large flexible aircraft.A nonlinear low-order aerodynamic state space model is required to model the nonlinear aeroelastic responses due to gust.Based on the proper orthogonal decomposition method,a reduced order modeling of gust loads was proposed.And then the open-loop and closed-loop reduced order state space model for the transonic aeroelastic system was developed.The static output feed back control scheme was used to design a simple multiple-in multiple-out(MIMO)gust alleviation control law.The control law was demonstrated with the Goland+wing model with four control surfaces.The simulation results of different discrete gusts show the capability and good performance of the designed MIMO controller in transonic gust alleviation. 展开更多
