The article deals with the method of turbulent flows modeling with the help of turbulence models, which have the form of algebraic expressions. In well-known numerical simulation systems such models were not used to simulate the flowing of viscous liquid. The proposed models of turbulence make it possible to simplify the software implementation of the equations describing the turbulent behavior of fluid flowing and increase the speed of computation. The developed system of the computer modelling using the specified models, has the simple and clear interface, takes a little space on a disk, is undemanding to system resources, can be supplemented with new problems at plug-in level. The obtained results of computer simulation of liquid flowing around solids of different shapes confirm the adequacy of the turbulence models used. It allows to apply them for modeling turbulent flows at the solution of practical problems.
