| Abstract: | By using the new method of variable separation with addition,semi-analytical solutions of 2-D imensional(2-D) steady incompressible viscous gas diffusion flow field are obtained in the paper,and suitable conditions are discussed.Besides the significance in theory,they can be the standard solutions for computational fluid dynamics(CFD).The paper enlarges the domain of using the method of variable separation with addition,and beneficially tries to obtain analytical solutions of complicated problem,such as 2-D steady incompressible viscous gas diffusion flow field. |
