An experimental study is performed on the effects of the distance of the heat transfer plates on free convection heat transfer in a stably stratified fluid between vertical plates. The stratified layer is formed using a sucrose aqueous solution, and is heated from one side wall at constant heat flux and cooled from the other side wall at constant temperature. The experiment is conducted for the distance of the heat transfer plates l=60mm, and the results are compared with those for l=20mm which are reported by the authors. As a result the thickness of the cellular layer shows weak dependence on the distance l, but the average heat transfer coefficient is affected greatly and becomes lower with increasing l.
