This study presents experimental and numerical investigation for three-dimensional heat transfer characteristics in a turbine
blade. An experimental setup was installed with a turbine cascade of five-blade channels. Blade heat transfer measurements were
performed for the middle channel under uniform heat flux boundary conditions. Heat was supplied to the blades using twentynine
electric heating strips cemented vertically on the outer surface of the blades. Distributions of heat transfer coefficient were
obtained at three levels through blade height by measuring surface temperature distribution using thermocouples. To understand
heat transfer characteristics, surface static pressure distributions on blade surface were also measured. Numerical investigation
was performed as well to extend the investigation to locations other than those measured experimentally. Three-dimensional
nonisothermal, turbulent flow was obtained by solving Reynolds averaged Navier-Stokes equations and energy equation.The shear
