Abstract
A forced convective heat transfer in a straight pipe rotating around a parallel axis with a large angular velocity has been studied by assuming an effective secondary flow due to buoyancy. Heat-transfer problems studied in this paper are commonly found when cooling electric generators or other rotating machines. Flow and temperature fields are analyzed by dividing them into a flow core region and a thin boundary layer along the wall. The analysis of a fully developed laminar flow under a constant wall temperature gradient condition consists of two parts in this report. The first part is common in various problems with secondary flows and the second part includes points for the present problem. The result shows that both the ratio of resistance coefficients and that of Nusselt numbers to the values for the Poiseuille flow are proportional to (Ra r.Re) 1 5 , (Ra r , Rayleigh number in the centrifugal field; Re. Reynolds number). The correction coefficients due to the Coriolis effect are also given.
