摘要

Highlights?A novel combined baffle-bluff micro-combustor is proposed for MTPV applications.?At the optimal baffle thickness, the average temperature improves by 6% and uniformity by 87%.?The combustion efficiency is most sensitive to the baffle length.?The wall conductivity predominantly affects the entropy generation rate.AbstractThis research is aimed at investigating a novel planar micro-combustor with combined baffle and bluff configuration for Micro-Thermo-Photo-Voltaic (MTPV) applications, numerically. It is shown that the novel combustor outperforms the similar configurations with only baffle or bluff, in terms of the flame stability, efficiencies, and emission. In addition, it is observed that the baffle thickness plays the key role in determining the flame location and, as the result, is the most important design variable controlling the temperature distribution and uniformity since the balance of heat tr
