According to the continuity equation,the momentum equation and energy equation of gas and liquid phase,the mixture loss model of the gas and liquid phase under the condition of having no mass exchanging between gas and liquid,isothermal and steady flow was gotten.

It is found by analysis that the flow resistance in the horizontal wellbore is made of three parts: wall friction loss, acceleration loss and mixture loss, and the mixture loss is mainly influenced by main flow velocity and perforation flow velocity.

In this paper,the numerical simulation technique is used to investigating the effect of different swept depth of a turbine last stage blades with forward swept orthogonal designing on the energy losses of the cascades.

Analyzed the changing of energy loss in turbine cascade with different backward wedge angles,and achieved the range of the backward wedge angles corresponding of the minimum energy losses on three typical sections in the turbine cascade.

Analyzed the changing of energy losses coefficient in turbine cascade with different backward curved angles,and achieved the range of the backward curved angles corresponding of the minimum energy losses on three typical sections in the turbine cascade.
