Heat and fluid flow characteristics of film flow along vertical grooved channels are investigated as a simple model of plate-type absorber. The film flow is affected by establishing a grooved part on the flat plate. Namely, it is expected that a film thickness becomes thinner at the edge of the groove as the flow deflects into the groove, and consequently fluid mixing is enhanced. In this research, in order to clarify the characteristics between the film flow pattern, heat transfer and groove depth, we have performed numerical simulations by using Volume of Fluid (VOF) method. In addition, we have also performed experiments with flow visualizations and compared the result with one of numerical simulations.
