Investigation of effects of combustor wall thickness on the flame stabilization limits for micro combustors with wire mesh

The scarcity of energy has led to the invention of alternative solutions to the conventional power generation system. Micro-power generation system is one of the potential sustainable solutions that provide better energy resource for small electronic devices as compared to conventional lithium-ion b...
