摘要: In the literature on turbulent flow various combinations of velocity, turbulence kinetic energy, and eddy viscosity models have been proposed for inlet boundary to a field. There appears be no rational criterion specifying conditions. The present study proposes select conditions by treating as part Using this criterion, any prescribed variation energy k, rate dissipation e, must satisfy governing field equations at boundary. Analysis previously used profiles in indicates that most these do not equations. To substantiate importance conditions, several reported numerical simulations using k-e are reconsidered determine if there is linkage between residual errors inlet...
