摘    要:本文把由温度引起密度变化的运动流体称为热可压流,并由无因次加热数来度量其压缩程度。它有别于气体动力学中以马赫数度量压缩性的由速度(因而压力)变化导致密度变化的可压缩流。列举和讨论了热可压流流动和传热的一些特征现象,它可望用于发展一些新的热控制技术。

关 键 词:热可压流,流动,传热

Abstract:This work refers to as the thermally compressible flow, the variable density flow due to temperature variation, with dimentionless heating number to describe its compressibility.The Thermally compressible flow differs from the compressible flow studied in gasdynamics, where the variable density flow is caused by velocity and cousequent pressure variation of fluid, with Mach number to describe its compressibility. Some features of the flow and heat transfer for the thermally compressible flow have been listed and discussed, which can expect to be used to develop some new technology of thermal control.
Keywords:thermally compressible flow  fluid flow  heat transfer
