Abstract : To solve the problem of free thermal convection in a stationary regime of liquid flow the similarity theory enables one to obtain a general formula in the form of Nu=f(GrPr), where Gr = Grasshof parameter; Pr = Prandtl parameter, Nu = Nusselt parameter. In this report an effort is made to obtain analytically the form of the function f with the aid of Leybenzon's integral ratio. Stationary thermal convectionnear a horizontal cylinder of infinite length is discussed. A cylinder of finite diameter is imitated as a linear source of heat.
