摘要
采用计算流体动力学CFD技术对某建材超市室内空气场形式进行数值模拟,预测了室内温度场、速度场以及浓度场,发现用散流器上送风,送风高度在5米左右时,送风温差在15K以上为宜,散流器垂直方向速度为3m/s时,人员的活动范围内的速度基本符合0.3m/s的要求,有污染物挥发时,通风安全系数应不小于9。验证了空调室内气流的动量传递、热量传递和质量传递的高度类似性。
the paper adopts the technology of computational fluid dynamics,numerical simulation to the airflow distribution of a refurbishing materials supermarket,forecasts the indoor temperature,velocity and concentration field.We discovered when the air jet with a diffuser from 5 meters or so in height,the air temperature difference is 15K or more appropriate,when the vertical speed of diffuser is 3m / s,the indoor velocity in the scope of personnel activities comply with the required rate 0.3m / s,when contaminants diffuse,the ventilation safety factor should be not smaller than 9.Also we verified the momentum transfer,heat transfer and mass transfer of the Indoor air has similarity in high degree.
