Outline of Final Research Achievements

Although the energy density of the waste heat released from automobiles, factories, and plants is low, high amounts are released. There has been multiple approaches to recover this waste energy; however, the fundamentals of this heat collection are not sufficient. The aim of this study is to produce a highly efficient waste heat recovery by developing a micro channel heat collector by passing fluids through a channel produced via a 3D array of periodic monosized particles. In order to produce heat collectors, evaluation of heat energy recovery efficiency based on thermic fluid simulations were performed. On the head of the monosized particles result were arranged into periodical organization,and determined the sintering condition for heat collectors.
