dc.description.abstractThe effect of transverse convex surface curvature on turbulent boundary layer flow and heat transfer in the entrance region of concentric annulus is studied analytically. The analytical results are obtained through a turbulent model based on the variable von Karman's constants, $\kappa\sb{\rm i},$ proposed by Kim and Lee in 1995. A computer program is developed for the calculation of the desired hydrodynamic and thermal characteristics. The solutions are found for the case of the heat transfer where the inner core surface is uniformly heated and the outer insulated. It is assumed that the fluid flow is turbulent everywhere and the thermodynamic fluid properties are independent of temperature. It is shown that both the friction factor and Nusselt number increase with the decreasing value of the inner core radius of the concentric annuli, r$\sb{\rm i},$ while the hydrodynamic and thermodynamic entrance lengths decrease with the decreasing value of the inner core radius, r$\sb{\rm i}.$ It is concluded that as in the fully developed turbulent flow, the effect of the transverse convex curvature in the developing region of concentric annuli seems significant.
