The paper offers a technique to calculate local hydraulic resistance in 2D and 3D channel geometries. The turbulent flow is described with Prandtl turbulent viscosity model with a single empirical constant which defines the turbulent viscosity coefficient. The technique is implemented in the hydrodynamic code MAH-3. 2D and 3D calculations were done to simulate the steady flow of almost incompressible gas through channels of different geometries modeling local hydraulic resistance of different types. For the fixed value of the empirical constant selected for the diffuser, the calculated resistance coefficients agree well with reference data.
