Abstract
Performance of a transonic low pressure turbine blade is investigated by using Radial Basis Functions (RBF) mesh morphing. The drag coefficient is defined as airfoil performance parameter. The drag coefficient of airfoil is computed using three dimensional Reynolds Averaged Navier Stokes (RANS) solver with hybrid grid topology. Laminar model, k-ω SST and k-ω Transition SST turbulence models are studied on the baseline blade configuration to investigate transition location and flow separation. Drag coefficient is reduced by 4.5% with RBF4AERO optimization tool.
