The simulation of flow and heat transfer in channels with ribbed surface
Abstract
A threedimensional finite difference code is used to predict fluid flow and heat transfer over a transverseribbed surface in a rectangular channel. The code uses the pressurevelocity formulation of the NavierStokes equation. The predictions reported are obtained using a standard kepsilon turbulence model of this code with a cartesian nonuniform grid. The code is implemented on a CRAY XMP24 computer. The code is described, as well as the method and results obtained for the two and threedimensional cases of the rectangular channel with ribbed bottom surfaces. A simulation and prediction is carried out of the temperature field (and associated heat transfer) when air flows through the rectangular channel with one heated ribbed wall.
