Multispecies and variable specific heat capacity numerical simulation study

摘要：

　　With the rapid development of computer science,numerical simulation applications in scientific research widely spread increasingly.Based on the Navier Stokes equations,studied the coupled calculation of the multispecies gas transport equation.Gas species covered O2,CO2 and H2O,and specific heat capacity γ changed with temperature and species.By comparing with experiment value of each species from certain literature charts we could verify that the variable specific heat results we had got were closer to the real gas field and met the needs of engineering calculations.This method of variable specific heat was applied to several flow field calculations and obtained desired results.
