摘要：
Using Navier-Stokes equations and Reynolds time-averaged rules, the turbulent motional differential equations of variable density and variable viscosity fluid in eylindrieal coordinates have been presented, and the turbulent motional differential equations of this fluid in pipe have been established. The concepts of the density turbulence stress and the viscosity turbulence stress have been presented.
