I want to do CFD analysis of a Gas Turbine blade on FLUENT software the known parameters are
Inlet Temp. = 900 C Inlet Velocity = 700 m/s Mass flow rate of air = 450 ton/hr Inlet pressure = 8 bar Outlet temp. = 600 C outlet Pressure = 3 bar I have generated the Grid in GRIDGEN software Kindly guide me what boundary conditions,inlet conditions and solvers etc i should use to solve my case? |

dont you have NGV with rotor blade? if no then you have to specify the angle at inlet (axial and tangential components with radial component = 0; specify the sign of axial and tangential components in accordance of right hand rule)
at inlet specify total pressure and total temperature and at outlet specify the mass flow outlet or corresponding static pressure (which produces the required mass flow rate) give fluid the required rpm and specify axis direction as per right hand rule. choose x,y or z (with value 1 or -1) as your axis of rotation keep the default conditions for hub and blade and for shroud : specify it as rotating wall with zero rpm in inertial reference frame also use the periodic boundary condition for the planes (two identical planes with identical mesh) between adjacent blades |

Since you want to do analysis of single blade, first thing you have to do is control volume creation for single blade. I.e separate out your blade from other blades in the problem.
2nd thing will be boundary condition specification. You can specify inlet and outlet according to what you know. Since you are doing single blade analysis common surfaces of blades should be specified as 'periodic boundary condition'. Hope it is clear to you. All the best Sabin Mathew |
