*2.5. Simulation Method and Initial Conditions*

The commercial software FLUENT 17.1 is used to simulate the heat transfer process, and the finite volume method is used as the governing equation. The simple algorithm is used to realize the coupling between pressure and velocity. The second order upwind scheme is used for the momentum and energy equations. The convergence residuals of the velocity dependent equation and the energy dependent equation are less than 10−6. The initial conditions are heating capacity of 392,857 w/m3 , the initial temperature of 303 K.
