This paper describes the influence of through-flow on the mixed convection in a slender rectangular channel. In a rectangular enclosure, the cinbection structure most often observed is rolls with axes parallel to the smaller side of the rectangular enclosure. If a through-flow is imposed on such convection, the fluid flows keeping its structure in the region that Ra number is large and Re number is small. In such a mixed convection, the flow pattern plays an important role in th eheat transfar process. In this study, the flow-visualization, by thermo-sensitive liquid-crystal suspension method were conducted covering wide Ra and Re rages. Consequently, the convection pattern was classified into three patterns by use of Ra and Re numbers.
