【摘要】 <正> 自从第二次世界大战末德国发明V-2火箭,特别是1957年苏联发射第一个人造地球卫星以后,航空和宇航技术高速发展,现在,飞行体的速度已远远超过第一宇宙速度(7.8公里/秒)。随着速度剧增,带来了低速飞行时不曾出现的特殊问题:一是高M数效应,一是高温对飞行介质的影响。高M数效应使得通常的Navier-Stokes方程失效。研究这方面问题,属于高速空气动力学范围。在实际问题中,高速必然伴随着产生高温,这两方面的效应交织在一起。热效应比起单纯的速度效应更本质,这使得高速高温流动现象及其介质性质的研究成为高温气体物理力学的一个最重要方面。更多还原

【Abstract】 The thermodynamic properties of high temperature gases arc important in science and technology. Air is most commonly used in practice. The thermcdy-namic properties of high temperature air over a wide range of temperature and density (or pressure) have been computed previously by a number of investigators. The present paper reports these results and discusses briefly various errors that were present in the computation of the thermodynamic properties of air. In addition, this paper gives a short review and recommends some results for the application in science and technology. Finaly, some problems which remain to be resolved are pointed out.更多还原
