本研究的目的是建立一种方法来估计温度分布的稳态平面波阵面在热粘性材料使用Hugoniot函数。为此，在波阵面中物质近似处于平衡状态的基本假设下，推导出波阵面温度的两个不可逆热力学方程。在第一个方程中，忽略了热传递，而在第二个方程中，热应力所做的功被热传递所抵消。在热传输的假设下，定性地评估了温度分布。该评价表明，如果粘度的影响较大，则第二个方程是有效的。这两个方程被应用到冲击压缩的氧化钇掺杂的四氧化锆高达140 GPa。第二个方程充分预测了激波后的温度，也相当准确地预测了激波前沿的温度。热传导的影响…
The purpose of this study was to establish a method for estimating temperature distributions in steady-plane-wave fronts in a thermoviscous material using a Hugoniot function. To this end, under the fundamental assumption that the material in the wave front is approximately in an equilibrium state, two irreversible thermodynamic equations for temperature in the wave front were derived. In the first equation, heat transport was neglected, and in the second equation, the work done by thermal stress was offset by heat transport. The temperature distributions were evaluated qualitatively under the assumption of heat transport. This evaluation indicated that the second equation was effective if the effects of viscosity were large. These two equations were applied to the shock compressions up to 140 GPa of yttria-doped tetragonal zirconia. The second equation sufficiently predicted temperature behind the shock and also fairly accurately predicted temperatures in the shock front. The influence of heat transport ...
