Evaluation of FIDAP on some classical laminar and turbulent benchmarks

Numerical solutions of the Fluid Dynamics Analysis Package (FIDAP) for some laminar and turbulent flow problems, namely (1) two‐dimensional laminar flow inside a wall‐driven cavity, (2) two‐dimensional laminar flow over a backward‐facing step and (3) two‐dimensional turbulent flow over a backward‐facing step, are presented. The consistent integration penalty finite element method is used with Q 2 /P 1 (nine‐node biquadratic velocity with linear discontinuous pressure) finite elements. Results of FIDAP on the above problems are compared with other numerical solutions and experimental data to evaluate its numerical accuracy. The influence of streamline upwinding is also investigated for all the test cases.
