A numerical simulation of the flow field and heat transfer in a rectangular duct with a turbulator using a predictorcorrector algorithm
Abstract
A numerical study of the flow field and heat transfer in a turbine blade internal cooling passage is described. Attention is focused on a short straight section of the rectangular passage which includes a single turbulator protruding from its floor. The twodimensional, transient, Reynolds averaged NavierStokes, continuity and energy equations are iterated to a steady state solution using the MacCormack explicit predictorcorrector algorithm. Turbulence closure is achieved through the use of the BaldwinLomax form of the CebeciSmith algebraic twolayer eddy viscosity model. Plots of skin friction, local heat transfer rate, streamlines, velocity profiles and temperature profiles are given. It was found that the widely used Reynolds Analogy greatly underpredicts the heat transfer rate as given by a direct calculation using Fourier's law.
