【Abstract】 The liquid status on the effect of the temperature difference inside the double curtain wall is researched. On the channels inside the double curtain wall, the Navier_Stokes momentum equations and the consecutive equations and the temperature field equations are constituted. Using the theory of one_dimensional liquid flow, the channel is divided into a series of discretional units, and the local analytical solution of the equations is founded. With the confined conditions and the connected conditions on the speeds and pressures and temperatures in the units, the whole numerical solution is transferred. Finally,the computer software is developed,and the example is introduced.更多还原
