Simulating Radiation of the G-type Radiant Cooler by the Monte Carlo Method Based on New Algorithms |
|
| Abstract: | During simulating radiation and calculating exchange factors of the parabolic reflector of the G-type radiant cooler, this research used the filtering algorithm to confirm the location of energy packets on the parabolic reflector and developed the direction of energy packets based on the tangent plane. Based on new algorithms, radiation and exchange factors of the parabolic reflector to other surfaces are simulated and calculated by the Monte Care method, and the results are analyzed. The results show that new algorithms can guarantee the precise of the simulation and calculation of the Monte Carlo method and the results become more accurate as more packets are included. |
| Keywords: | The Monte Carlo method Exchange factor Radiant cooler |
