摘要

Experiments are performed to study the mixed convection flow and heat transfer in a horizontal rectangular channel heated form a side. The channel is made of tow vertical parallel plates with one of the plates heated uniformly and the opposite plate well insu- lated. The gap between the parallel plates is small and the height to gap ratio of the channel cross section is 6.67. Both flow visualization and the heat transfer along the heated wall are measured. The Reynolds number ranges form 317 to 2000, and buoyancy parameter, Gr/Re~2, from 0 to 20000 and Pr of the air flow is 0.7. flow structure inside the channel is visualized by injecting smoke at the inlet flowing along the heated side wall.
