Abstract: The requirements of improved heat transfer performance on turbine surfaces and internal cooling passages drive the research into exploring new methods for efficiency enhancements. The addition of ribbed structures inside ...

Abstract: Thermal management of turbine airfoils is a critical design consideration, but the impact of unsteadiness on heat transfer of attached flow regions has received less attention in the literature. When turbine surfaces are ...

Abstract: In this study, acoustic actuation was applied experimentally to massively separated flows on simplified hump geometries, which mimic the pressure distribution over high-work-and-lift low Reynolds airfoils. The acoustic ...

Abstract: This research effort is related to the detailed analysis of the temporal evolution of thermal boundary layer(s) under periodic excitations. In the presence of oscillations, the nonlinear interaction leads to the formation ...
