Diffusers are extensively used in many industrial aspects. So, diffusers with high efficiency are desired under both spatial and cost's limitations. In our previous studies, we proposed a flow deflector inside the diffuser-part of an automotive catalytic converter, in order to reduce energy loss and to improve thermal uniformity. In this study, we experimentally and numerically investigate the influence of the downstream substrate upon the effectiveness. As a result, it is revealed that the flow deflector is effective for diffusers as well as catalytic converters. By computation, we have shown the flow inside the diffuser with the flow deflector.
