It was found that the streamwise local heat transfer coefficients at a lower wall are higher than that at a side wall except the aspect ratio AP=1. As an aspect ratio increases, the local values on both walls increase, moreover the heat transfer coefficients at far downstream attain to the results obtained from the circular duct or the parallel plate duct. The dependency of an aspect ratio on the heat transfer characteristics of the rectangular duct is also presented., 紀要論文}, pages = {27--33}, title = {長方形流路内の伝熱特性に関する研究 (アスペクト比の影響)}, year = {1995} }
