摘要：

A new method for the prediction of steady turbulent flow and heat transfer in the gap between a railway train and the wall of a long tunnel is proposed. The theory is based on the assumption of power laws for the velocity profiles adjacent to the rough train structure and the smooth tunnel. The friction and heat transfer coefficients at the two surfaces are determined using correlations for imaginary rough and smooth ducts in place of the boundary layers. Preliminary calculations have been made for a realistic situation.
