Numerical Investigation of Heat Transfer Enhancement Using Hybrid Vortex Generator Arrays in Fin and Tube Heat Exchangers
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This is a novel study for assessing the heat transfer enhancement in a multirow inlinetube heat exchanger using hybrid vortex generator (VG) arrays, i.e., rectangular winglet pairs (RWPs) with different geometrical ...
Analysis of the Unsteady Flow Field Inside a Fan-Shaped Cooling Hole Predicted by Large Eddy Simulation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Film cooling is a common technique to manage turbine vane and blade thermal environment. Optimizing its cooling efficiency is furthermore an active research topic which goes in hand with a strong knowledge of the flow ...
Numerical Investigation of Film Cooling Enhancement Using Staggered Row Mixed Hole Arrangements
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The paper presents a novel study on film cooling effectiveness of a 3D flat plate with a multihole arrangement of mixed hole shapes. The film cooling arrangement consists of two rows of coolant holes, organized in a staggered ...
Enhancement of Film Cooling Effectiveness Using Rectangular Winglet Pair
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This study deals with the film cooling enhancement in a combustion chamber by the use of rectangular winglet vortex generators (VGs). Rectangular winglet pair (RWP) in both the common-flow up and the common-flow down ...
