Abstract: In this paper. using Navier-Stokes equations and Reynolds time-averaged rules,the turbulent motional differential equations of voriable density and variable viscosity Newtonian fluid have been presented. and the turbulent motional differential equationsof variable density and variable viscosity Newtonion fluid in open channel have beenfurther proposed. The concepts of the density turbulence Stress and the viscosityturbulence stress have been firstly presented in the paper for the first time.
