Fluid material properties include the density or molecular weight, viscosity, heat capacity, thermal conductivity, and mass diffusion coefficient, standard state and molecular motion parameters. (2) As the boundary conditions, the inlet and outlet pressure is set as 0 Pa, room temperature T 293K. (3) Initial values including pressure, velocity, and temperature and turbulence coefficient should be accorded with the real physical phenomena as far as possible to ensure convergence and accuracy.
