Simulation of unsteady-state hydrodynamics under conditions of turbulent flow in pipes
I. V. Derevich Moscow State University of Environmental Engineering
Abstract:
Modern approaches to simulation of turbulent flows are used to analyze the effect of nonstationarity of the flow rate on the parameters of turbulence. The flow rate variation in the case of homogeneous turbulence with constant shear of velocity is treated. The dynamics of the second moments of velocity fluctuations at constant flow rate are investigated. Calculations of unsteady-state pipe flow are performed within the two-parameter model of turbulence. Qualitative comparison is made of the theoretical and experimental results.
