The authors have proposed an advanced fuel configuration to overcome the defect of conventional hybrid rockets, i.e., the low thrust level. The key feature of this new type of hybrid rocket, named Cascaded Multi-staged Impinging jet (CAMUI), is that the cylindrical fuel blocks with two ports parallel to the axis are arranged in a row in the combustion chamber. This fuel configuration allows mixing and combustion to occur in and around the impinging jet regions. In the present paper, a CFD simulation clarifies the fundamental features of the flow field and the heat transfer distributions in the CAMUI hybrid rocket grain. Following results are obtained: Higher heat transfer occurs near the edge of the impinging jet region. A fountain flow caused by the collision of the wall jets enhances the heat transfer on the backward end of the upstream fuel block. A semi-cylindrical swirling flow appearing near the inlet of the fuel port increases the convective heat transfer in this region.
