چکیده انگلیسی
This study used a numerical method to investigate the thermal performance of a 2.0â¯kW burner in heating the cabin of an electric passenger vehicle. The thermal performance (including temperature distribution, velocity distribution, heat flux, burner efficiency) and fuel performance (including species variation, NOx concentration) with the fuel types, mass flow rates and the inlet temperature were investigated with a numerical simulation using the standard k-ε, RNG k-ε and realizable k-ε turbulence models. The results were validated within 8% that of experimental data obtained by the Korea Institute of Energy Research, Republic of Korea. The standard k-ε turbulence model with the eddy dissipation combustion model showed a close agreement with the experimental data, compared to the RNG k-ε and realizable k-ε turbulence models. As a result, a maximum heat flux of 2171.5â¯W was observed for butane at a fuel mass flow rate of 0.000057â¯kg/s and an air inlet temperature of 0â¯Â°C. The maximum burner efficiency of 96.7% was observed for methane at a fuel mass flow rate of 0.000030â¯kg/s and at an inlet air temperature of 0â¯Â°C. A minimum NOx concentration of 5.5â¯ppm was observed for propane at a fuel mass flow rate of 0.000030â¯kg/s and inlet air temperature of â20â¯Â°C. In addition, the butane fuel could be suggested to be effective for the 2.0â¯kW burner to heat the cabin of an electric passenger vehicle.
