Abstract

The heat transfer coefficient in a plane channel was estimated theoretically. In the framework of assumptions made in the present research, a correlation in the form of Lyon’s integral was obtained for energy equation. It was employed for analytical estimation of heat transfer coefficient in laminar flows and liquid metal flows, in which molecular heat transfers prevail over turbulent one. The computational results comply with the literature.
