摘要
The momentum and heat transfer between a fully developed turbulent fluid flow and a moving core of fluid or solid body in concentric annular geometry is studied analytically based on a modified turbulence model. The heating condition is a uniform heat flux at the core tube only. The effects of various parameters such as the relative velocity, the radius ratio, etc. on friction factor and Nusselt number are investigated. © 1990.
