Abstract: When the operating condition of a gas turbine engine changes from one steadystate to another, the cooling must ensure that the solid's temperatures never exceed the maximum allowable throughout the transient process. ...

Abstract: The heat transfer coefficient (HTC) is often averaged spatially when designing heat exchangers. Since the HTC could vary appreciably about a heat transfer enhancement feature such as a pin fin or a rib, it is of interest ...

Abstract: The adiabatic effectiveness of film cooling (η) has been characterized by the density (DRh) and blowing (BRh) ratios. In this study, dimensional analysis and computations based on Reynolds-averaged Navier–Stokes (RANS) ...

Abstract: Counter-rotating vortices, formed by the interaction of film-cooling jets and the hot gas flow, adversely affect the performance of conventional film-cooling designs. Downstream vortex generators have been shown to improve ...

Abstract: In the context of waste gas energy recovery and management, the gray relational analysis method is applied to construct the optimum parameters and management of the operation conditions for a heating furnace used in the ...

Abstract: Downstream vortex generators that involve a pair of rectangular plates arranged in an open V-shape placed just downstream of each film-cooling hole were shown to create flow and vortical structures that entrain lifted ...
