A NEW SIMULATION SYSTEM FOR RADIATION CALCULATION WHEN OPAQUE AND HALF TRANSPARENT OBJECTS EXIT TEGOTHER
Here a generalized 3-D radiation simulation system is developed with Monte-Carlo and Gebhart method. There are two kinds of basic units in the system, which are surface unit for opaque objects and body unit for transparent objects respectively. When the bundles were emitted from certain point or surface with Monte-Carlo method, it would enter into an opaque surface or a transparent body. For the former, it would be reflected and absorbed. However, when the second situation happened, there is the third process named penetration beside above two processes. Those three processes would be continued until the bundles reach an opaque surface. With calculating the amount of bundles and that absorbed by another surface or body, the direct area exchange index could be obtained. With Gebhart method and the calculation of net angle coefficient, the radiation energy exchange with short wave and long-wave radiation could be calculated easily.
