The simulation of flow and heat transfer in channels with ribbed surface
Abstract
A three-dimensional finite difference code is used to predict fluid flow and heat transfer over a transverse-ribbed surface in a rectangular channel. The code uses the pressure-velocity formulation of the Navier-Stokes equation. The predictions reported are obtained using a standard k-epsilon turbulence model of this code with a cartesian nonuniform grid. The code is implemented on a CRAY X-MP24 computer. The code is described, as well as the method and results obtained for the two- and three-dimensional 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.
