Abstract: The need for better automotive technologies to improve fuel economy, while meeting stringent vehicle emission standards, grows with the demand for environmental protection and rising fuel prices. A new technology, designed and patented by Vida Fresh Air Inc., offers emission reduction while improving fuel economy. In this study, experimental and numerical investigations are performed to understand the flow through the catalytic converter, commercially known as CleanalyticTM, using a scaled-down test rig. Experiments are conducted using hot air flow to evaluate the thermalhydraulic characteristics of the new technology. The measurements are performed for Reynolds number of 43,000 and free stream temperature of 177 ºC. These conditions were selected to achieve thermal and hydraulic similarity of actual test conditions for engines. The numerical investigations are performed using ANSYS Fluent and the model predicted the experimental measurements within ±6 %. The use of CleanalyticTM improved the performance of the catalytic converter.
