Abstract: According to the mechanism of the effect of pneumatic heat on viscous modulus μ_t   diffuser grid flow field is evaluated with NASA67 . Navier-Stokes equations, Baldwin-Lomax algebraic turbulence model, finite volume method and Runge-Kutta time stepping schemes are used for analyzing the flow field of diffuser grid, where the effect of pneumatic heat on viscous modulus μ_t   is take n into account. The extensive results indicate that comparing the calculation without the effect of pneumatic heat, the proposed evaluation is closer to the experiments to suit of engineering applications.
Keywords: diffuser grid, flow field, turbulent, viscous modulus.
