Maxwell和Cattaneo的时滞思想在冲击波和Rayleigh-Benard问题中的应用
Maxwell and Cattaneo's Time-Delay Ideas Applied to Shockwaves and the Rayleigh-Benard Problem
摘要：
我们应用麦克斯韦和卡塔内奥的松弛方法来分析二维粘性导热流体中的强激波。麦克斯韦弛豫时间的合理值的良好协议的结果。如果粘性弛豫时间太大，则会导致不稳定性。这些松弛项对慢节奏亚音速问题的影响可以忽略不计，如这里对两滚和四滚瑞利-贝纳德流所示。
英文摘要：
We apply Maxwell and Cattaneo's relaxation approaches to the analysis of strong shockwaves in a two-dimensional viscous heat-conducting fluid. Good agreement results for reasonable values of Maxwell's relaxation times. Instability results if the viscous relaxation time is too large. These relaxation terms have negligible effects on slower-paced subsonic problems, as is shown here for two-roll and four-roll Rayleigh-Benard flows.
