Conjugate Heat Transfer Analysis of Convection-cooled Turbine Vanes Using γ-Reθ Transition Model

Numerical Simulation of Laminar-Turbulent Transition on a Dolphin Using the γ-Reθ Model

The γ-Reθ-model, a two equation, correlation-based transition model using local variables, has been employed to predict the extension of the laminar regions on a stiff geometry of the common dolphin (delphinus delphis) moving in the Reynolds regime of 5.5 ·10 to 10. Mesh independence was gained for a domain resolution of approximately 30 million cells in an unstructured polyhedral mesh with a p...

Conjugate Heat Transfer From a Two- Layer Substrate Model of a Convectively Cooled Circuit Board

Turbine Blade Cascade Heat Transfer Analysis Using CFD –A Review

Heat transfer analysis on a turbine blade cascade using CFD is reviewed in this paper based upon the literature available. The flow conditions across turbine blades are complex because of three dimensional configuration of the blade. Axial flow turbine blade design is hectic because understanding of control flows, prediction and analysis is a tedious task. The flow behaviour in a turbine blade ...

Fluid Flow and Heat Transfer of Nanofluids over a Flat Plate with Conjugate Heat Transfer

The falling and settling of solid particles in gases and liquids is a natural phenomenon happens in many industrial processes. This phenomenon has altered pure forced convection to a combination of heat conduction and heat convection in a flow over a plate. In this paper, the coupling of conduction (inside the plate) and forced convection of a non-homogeneous nanofluid flow (over a flat plate) ...
