Abstract

Commercial vehicles require high power and high endurance. These vehicles run longer distances than sedans. Hydrogen electronic vehicles have the merits in commercial vehicles. The range distance can be extended by adding hydrogen tanks. To develop a high power and high endurance air compressor, controlling its temperature is important. The partial temperature rise lowers the performance and endurance of an air compressor. The temperature, pressure, and mass flow rate are simulated by CFD. The results are compared with experimental results. The differences were less than 3.6%. The design modifications of diffuser holes are simulated. The correlations with design modifications showed that a large mass flow rate might deteriorate the compression rate. A proper diffuser hole can lower the temperature rise and maintain the compression rate.
