Abstract
In recent years, the trend towards miniaturization has driven the advancement of micro combustion-based
power generators, with the Micro-Thermophotovoltaic (MTPV) system
emerging as a promising technology. This doctoral research aims to enhance micro combustor
performance through innovative solutions. It investigates a novel micro combustor
design featuring equidistant angled ribs on the inner wall of the downstream
channel. The study explores flow dynamics, combustion behavior, and thermal
performance, revealing significant improvements in wall temperature levels and thermal
efficiency with the introduction of angled ribs. Increasing rib number and heights further
with the micro-combustor cross section enhances thermal performance by facilitating
ignition and sustaining stable flames. The proposed micro -combustor configuration
demonstrates superior thermal characteristics, contributing to the development of more
efficient and sustainable energy generation technologies. Addressing existing research gaps,
particularly in rib geometries, the study emphasizes the importance of an integrative
analysis approach. By bridging the gaps, it aims to advance the field of micro -combustion
and provide valuable insights for future innovations in sustainable power generation.
