得到并讨论了近超临界范德华气体边界处温度阶跃传播方程的解析解。在长时间尺度上给出了速度场和热力学场的定量性质。给出了热传递比纯扩散过程加速的定量证据。通过对piso算法的数值求解，验证了所得解析解的有效性。
The analytical solution of the equations describing the propagation of a temperature step at the boundary in a near supercritical van der Waals gas is obtained and discussed. The quantitative properties of the velocity and thermodynamic fields are given on a long‐time scale. Quantitative evidence of the speeding up of the heat transport compared to a purely diffusive process is given. The numerical solution obtained by means of the piso algorithm, which is performed and discussed confirms the validity of the obtained analytical solution.
