A Numerical study has been performed in order to investigate the heat transfer characteristics of a hydrate slurry transported by a visco-elastic fluid flowing between parallel plates with a one-sided cavity. The length were changed in three steps from 50 to 200mm, while the rib height, rib length and the width of wide flow path were fixed. The results were compared with those in the case when water is used as transportation media of hydrate particles. From the results, it is found that hydrate particles flows over the cavity without penetration in the case when solvent is Newtonian fluid (water). On the other hand, hydrate particles are observed effectively to penetrate into the cavity by Barus effect in the case of visco-elastic solvent. This causes effective heat transfer from the bottom wall of the cavity.
