This paper focuses on the description of the SIMPLE algorithm modification for the case of uncompressible flows and the applicability of the implemented algorithm for the calculation of transonic compressible flows within the LOGOS program package. The problems about flow over an airfoil and inside a diffuser are used to demonstrate the capabilities of the implemented algorithm in terms of reaching acceptable accuracy and convergence velocity when various schemes of convective component discretization are used and other computational parameters are changed. The obtained results are compared with the data of well known experimental tests. Keywords: SIMPLE algorithm, incompressible transonic flows, schemes of convective component discretization, LOGOS program package.
