Under the conditions of different solar wall size of air channel thickness and so on, Conclusions can be simulated by using CFD software.
The thickness of the cavity C and the outlet height D are variables in this simulation.
Select the thickness of the cavity in this simulation, respectively 50mm, 100mm and 150mm.
Analysis of simulation application software and its boundary condition Fluent is more popular in the international commercial CFD software package.
But when the volume of make-up air is 600 m3/h, the amount of energy saving is 52353.52 KJ so the quality of energy saving is the best. 3 For the width of the wall and the height of the air supply outlet in the simulation, simulation results show that the heating capacity slightly decreased with increasing the width of the solar wall.

At the same time,from the former chapter of the hottest month of the numerical simulation can be seen that the use of the open system can also satisfy the requirements of the subway specification，then an open systems can be acceptable in Shenyang area .

The six degree of freedom simulation is carried out with the previous results.
By the use of CFD, reference [1] has studied supersonic flight static stability of certain types of conventional tail shells.
By the use of six-degree-of-freedom simulation, reference [2] has researched flight dynamic stability of certain types of non-symmetrical tail shells.
