【Abstract】 Usually the experimental method was used for the design of marine gas turbine inlet air filter. Now a useful theoretical approach is presented by use of CFD. The flow field in inertial stage, as the main part of inlet air filter, was simulated by numerical method. The flow field of typical structure was calculated, and the discussion about the influence of structure parameters on inlet air filter performance was done. Some suggestions may be helpful for the design of inertial stage.更多还原
