| Abstract: | The heat flux distribution of an infrared lamp is computed based on Monte Carlo method,and the database is founded.Then,the heat flux distribution of the infrared lamp array is simulated with the consideration of the direct heat flux of the infrared lamp,reflect ration of the baffle-board and the mass of leaked light.The coordinates of the lamps have been taken as the optimization parameter,and the optimization of the heat flux distribution for the infrared lamp array are computed based on Genetic Algorithm... |
