Abstract
The performance of a recently developed calculation procedure for steady incompressible flows is assessed in a variety of three‐dimensional sudden expansion type flows representative of those encountered in several types of industrial equipment. The calculation procedure, called here BLIMM (for block‐implicit multigrid method), is based on a coupled solution of the three‐dimensional momentum and continuity equations in primitive variables, using the multigrid technique. Different Reynolds numbers and finite difference grids are considered for each flow situation. The rates of convergence and the computational times are reported for each case.
