| 中文摘要: | For the thermal blooming of the beam path indoor, solving the coupling equations of optical field and fluid field completely is a meaningful and important subject. In this paper a numerical emulation platform for solving the coupling equations was established. The laser beam coupled with the fluid field by the method of User Defined Function which was offered by the CFD software. Thermal blooming effects in the beam path indoor of the line pipe are modeled by the established numerical emulation platform. In order to testify the rightness of the numerical emulation results, steady-state thermal blooming effects in the axial pipe flow are calculated by the theoretical methods, and corresponding experiments are also carried out. The results indicate that the numerical emulation platform is creditable in simulating the thermal blooming of axial pipe flow. © 2013 SPIE. |
