Effects of major parameters on micro-combustion for thermophotovoltaic energy conversion

A three-dimensional computational model of H2–air premixed combustion in non-circular micro-channels for a thermo-photovoltaic (TPV) application

“…Wenming et al [10] experimentally observed that the wall temperature and power output of a TPV increased with a decrease in wall thickness. In another experimental study, Pan et al [11] observed that a thin combustor with slightly rich in fuel mixture resulted in decreased axial conduction and a 150 K increase in the wall temperature. In addition, several techniques such as heat recuperation and heat recirculation have been extensively carried out to experimentally investigate and improve the flammability limits of a micro-combustor [12][13][14][15][16][17].…”

An experimental study of methane–oxygen–carbon dioxide premixed flame dynamics in non-adiabatic cylinderical meso-scale reactors with the backward facing step

“…Increasing the flow residence time scale increases the ratio between the flow residence and the reaction time scales in meso and micro-scale reactors. In this regard, Li et al [21], Yang et al [22], and Pan et al [23] showed that the backward facing step can significantly affect the flame stability and temperature distribution in meso and micro-scale reactors. Also, Yang et al [22] maintained that the backward facing step can effectively control the flame position and operation range in meso and micro-scale reactors (combustors).…”

Hydrogen/oxygen premixed combustion characteristics in micro porous media combustor

“…Due to high energy density, compact and portable, micro power generators, such as micro gas turbine [1], micro rotary engine [2,3], and micro free-piston IC engines [4] are being developed. Compared with these kinds of micro power generators with high speed moving parts, direct energy conversion concepts, such as micro thermoelectric device [5] and micro thermophotovotaic (TPV) system [6][7][8][9] are attracting more attention.…”
