Simulation Studies Of Premixed N-Pentane/Air Liquid Micro Combustion

With latest improvements in MEMS, combustion based Micro-Power generation devices are seen as alternatives\ud for conventional batteries because of the high energy densities of Hydrogen and other hydrocarbon fuels. An\ud important feature of micro-power system is to utilize the combustion of fuel or propellant in the micro-burner to\ud produce the gas with high temperature and high pressure to drive turbines or other power units, which convert\ud chemical into energy directly or indirectly other forms of energy, for example heat or power. We have\ud concentrated on the usage of Micro combustion as a substitute for conventional batteries .In our study, a Micro\ud Combustor of 1mm x 10mm is taken for Numerical Study. Combustion characteristics of N Pentane-Air mixture\ud in a planar micro-channel is studied numerically. We have performed the liquid fuel combustion of n-Pentane\ud and air to study the effects of liquid fuel combustion in a micro channel. The effect of axial velocity inlet, on\ud exhaust gas temperature and Hydrogen Peroxide addition on exhaust gas concentration was analyzed\ud respectively. We also investigated numerically the combustion characteristics under different conditions such as\ud by varying the DPM, Number of Fuel Streams, and Spray Angle and so on. For this numerical analysis, an\ud experimental model is considered as reference, and the geometry and the boundary conditions are taken from it\ud for the purpose of simulation. In this study, n-Pentane is introduced as liquid droplets at the centerline and the\ud liquid combustion is simulated numerically
