Abstract
The steady laminar flow in a two dimensional curved channel was studied numerically to investigate the effect of curvature ratio and mass flow rate on the characteristics of the flow. The curved passages are considered ssential component in many equipment such as; heat exchangers, chemical and nuclear reactors, air conditioning ducts, efrigerating systems, air intakes in turbo maclllnel)’ parts, and others that require change in the direction to suit the compact design. Hence, the flow in curved passages have been of interest to many investigators to understand some of the important phenomena occurring in flow through them. The survey shows that there are several shapes for curved passages; circular, square, rectangular and others. The thesis presents a summary of the previous studies in curved passages including : the methods of solving such flow problem, ”either experimentally, analytically or umerically and showing the difficulties that face the investigators, and their assumptions to facilitate the solution.A mathematical fluid flow and heat transfer model governing the flow in two dimensional curved channel was developed. The partial differential equations describing the flow in the curved channel were transferred into algebraic equations by finite difference techniques. Adaptations had been done on a SIMPLE algorithm to suit the problem. Modifications had been carried out on the old version of SAMPLE algorithm to make it more consistent and faster by; (1) introducing the SAMPLE-C. algorithm, (2) applying the block correction ii
