摘要
讨论了由于热浮力和质量扩散引起的垂直圆柱自然对流方程组，考虑了粘性耗散项的影响，给出了定常和非定常流动时存在相似性解的条件及相应的相似性解；同时证明了，如果考虑粘性耗散项，定常和非定常情况下的此类流动均无相似解存在．
The eqtrations of vertical natural convection nows induced by buoyanCy and mass diffusion from a vertical cylinders are discused. The effects of viscous dissipation are considered. For steady and unstedy flows, the ekistencc conditions and similarity solutions arc given. If the viscous dissipation is considered, then in any one of these flows docs not ealst similarity.
