Opis:: The paper is devoted to the problem of boundary conditions influence on the quality of the solution obtained with use of k-? turbulence models. There are calculation results for different boundary conditions and two methods: standard k-? and RNG k-? in the paper. The flow parameters obtained from the calculation are compared with our own measurement results. Moreover, the influence of input data on the inflow edge on sensitivity coefficients is shown and analysed in the paper. The research is performed for components of velocity and turbulence kinetic energy.

Opis:: The paper presents the dependence between the degree of approximation of flow property functions and the sensitivity coefficients which are results of sensitivity analysis of solution to the coefficients of the k-ĺ turbulence model. It is shown that the model coefficients are factors of derivatives in the set of equations which describes the k-ĺ turbulence model. Because of this fact, when the term with the given parameter is large enough then the value of this parameter, being only the factor, has also larger influence on the solution. The numerical research is preceded by the description of calculation of sensitivity coefficients and their physical sense. The problem is presented for three tasks of incompressible steady flow around square and rectangular models with use of the standard and RNG versions of the k-ĺ turbulence model.
