Dissertation for the degree of the candidate of technical sciences by specialty 01.02.05 – mechanics of a liquid of gas and plasma. – National technical university of Ukraine “Kiev polytechnical institute, Kiev, 2000.
In a thesis the physical analog of development of internal flows in an open flow is justified, on the basis of which, the hydrodynamic description of their gear is designed at a coherence of three-dimensional distribution of velocities with a field of pressure. As closing model the algebraic ratio of Reynolds stresses together with modified model of turbulence are used, that allows is realistic to describe processes, which can not be forecast within the framework of models with isotropic turbulence. Is designed methods of numerical realization of offered mathematical models, in three-dimensional space of the arbitrary form, on the basis of modern computing methods and effective algorithms of the gas hydro-dynamics.
The thesis contains experimental researches of a velocity’s field in view of internal flows in an artificial oblate channel. The numerical simulation has allowed to open an internal nature of an anisotropic condition on the basis of a compass adjuster of a tensor of turbulent stresses. The practical introduction is executed on actual objects of a road-transport complex of Ukraine.
