Approximate method for estimation of friction forces for axisymmetric bodies in viscous flows
Abstract:
The paper considers verification method for numerical modelling of bodies in viscous flow. The verification is based on approximate semi-empirical approach. The approach uses experimental data for flat plate and 'effective length' method. One can apply approximate approach to estimate friction coefficient and specific thicknesses of boundary layer for axisymmetric objects placed in viscous flow. Practical aspects of approximate approach and numerical results are described. Described approach can be used for verification and improving of numerical models in the case of lack of experimental data.
