Description
Summary:•Numerical performances of IDEAL and SIMPLERR are analyzed and compared.•SIMPLERR can be regarded as a special form of IDEAL.•The robustness of IDEAL is much better than SIMPLERR.•In general, the performance of IDEAL is superior to SIMPLERR. In this paper, the numerical performances of the algorithm IDEAL proposed by the present authors in 2008, and the recently proposed (2017) SIMPLERR are systematically analyzed and compared via six incompressible fluid flow and heat transfer problems. It is found that the two algorithms are almost identical when the second inner iteration number of IDEAL is fixed at 2. In general, the robustness and convergence of IDEAL are much better than SIMPLERR. The reason why the performance of SIMPLERR deteriorates with the increase of the first inner iteration number is analyzed and detailed comparisons in the robustness and computing time are presented.
