In order to investigate the optimum geometric condition for a heat transfer augmentation technique using the Barus effect of visco-elastic fluid, heat transfer experiments have been performed in a cavity. In this paper, the length of a cavity mounted on one side in a channel flow was changed from 50mm to 200mm. The results indicated that the mean Nusselt number on the cavity bottom in the cases of visco-elastic fluid becomes smaller than that in the corresponding cases of water under the present conditions, but it was found that the visco-elastic fluid improved heat transfer characteristics behind the upstream wall of the cavity at least.
