| 摘 要： | By introducing the extremum law of energy dissipation rate into the investigationof turbulent flow,the closure problem for the basic equations is briefly discussed in connectionwith a newly suggested semi-empirical turbulent flow model.As a result,several unknownfunctions which cannot be solved by the existed semi-empirical models are obtained in the presentpaper.It is shown that the turbulent flow models,as the constraints to the extremum problem,have direct influence on the final results of the primary parameters.
