Numerical simulations for every flow require enormous computing time during iterations. In order to solve this problem several techniques have been proposed, as for example, a multigrid technique. A method using fuzzy reasoning is one such technique. We studied the possibility of accelerating computation with fuzzy reasoning in 2D incompressible laminar flow calculations. In order to obtain qualitatively correct velocity distributions some rules were constructed on the basis of human reasoning. Viscous and obstacle effects were introduced. In addition the recognition of the wall was programmed in order to find the separation point and the backward region. It was found that our procedure can realize a considerable acceleration in the calculation of channel flows which have some convexities and back-step flows.
