The Institute of Fluid Science, Tohoku University, and Hitachi Astemo, Ltd. have established a joint research department and have been able to obtain results in the first and second phases. In the third phase, as “Fundamental research of advanced vehicle technology (Hitachi Astemo)Ⅲ”, the next-generation inverter that drives the motor will be ultra-compact, lightweight, and high-performance for future vehicle electrification toward the realization of a low-carbon society. We will promote the fundamental research to realize those kinds of basic technologies. The research conducted by the Collaborative research division is related mostly to the enhancement and the application of the simulation technology based on computational fluid dynamics and experimental verification. By conducting collaborative research between Hitachi Astemo, Ltd. and Institute of Fluid Science, Tohoku University, aims to create new value directly connected to development of appealing products with excellent environmental performance based on the research of such next-generation technology.
