The turbulent flow of water with variable Prandt number Prt
Języki publikacji
Abstrakty
The paper presents numerical calculations of turbulent exchange of momentum and heat in the flow of water at the inlet region of a circular pipe. The calculations are based on the low Reynolds number kappa-epsilon turbulence model, taking into account the changes of the turbulent Prandtl number Prt across the pipe. The obtained results of numerical calculations were compared with corresponding results of experimental work and other analytical ones avaiable in the literature. The comparative analysis of the numerical results and other, both experimental and theoretical ones, evidenced a high degree of their conformity.
