Flow in a two-dimentional square cuvity was investigated primarily by visualization using white starch powder or aluminum powder suspended in water ; the flow was generated by sliding the cavity model itself on a stationary flat plate. Experimental flow patterns at Reynolds number up to 1000 were compared with those obtained by numerical calculations. It was found that the experimental location of the center of vortices agrees well with the calculated one. On the other hand the sizes of secondary vortices in the experiment was somewhat smaller than those in the numerical calculations. A velocity profile through the center of primary vortex, experimentally obtained along a vertical line by using the digital image processing technique, showed fairly good agreement with that of the calculated profile.
