Abstract
B coordinate techniques coupled with standard finite difference procedures are used to solve irregularly shaped bifurcated channel flow numerically. The approach is applicable to two-dimensional and axisymmetric laminar and turbulent flow. A two-equation eddy viscosity model is used to model the Reynolds stresses. Solutions were obtained for a range of Reynolds numbers of 1350 to 750,000. It was found that the first-order terms generated by the transformation process and those generated from the Reynolds stresses must be individually upwind differenced to obtain a converged solution. The metric coefficients generated by the transformation creates the need for large core storage or off-line storage with large input/output time.
