Numerical modeling of turbulent shear flow in curved channel
The paper is dedicated to simulation of three-dimensional turbulent flow in curvilinear canal with right transverse section. For full develop turbulent shear flow on the basis of equation of second order one point moments for movements enclosed by semi-empirical Kolmogorov-Roth’s hypothesis the expressions for moments of second order depending on average flow characteristics and functions taking into account curvature influence are obtained. On the basis of Reynolds’ equation by numerical method the problem of turbulent flow in curvilinear canal is solved with small curvature. Calculation results are compared with results of right numerical simulation.
