For natural convection in the geometrically complicated channel or natural convection caused by the accidental stop of driving system in forced convective channel, the convection flow is suppressed by flow resistance due to such channel itself or an equipped driving system, and the lopsided flow may take place. This could result in serious influences on the heat transfer in the channel. In order to investigate fundamentally the natural convection flow and heat transfer in such the channel, the vertical channel with rectangular cross-section was employed, in which both vertical walls were symmetrically heated with uniform heat flux and the flow resistance was given by small clearance between the lower end of channel and a wide horizontal floor. Flow pattern was observed by illuminating smoke filled in the channel and the heat transfer coefficient was measured. Heat transfer coefficient is discussed in connection with the flow pattern.
