Abstract
Using Navier-Stokes equations and Reynolds time-averaged rules, the tu rbulent motional differential equations of variable density and variab le viscosity fluid in cylindrical coordinates have been presented, and the turbulent motional differential equations of this fluid in pipe h ave been established. The concepts of the density turbulence stress an d the viscosity turbulence stress have been presented.
