CFD Simulation Research of Small Space with Large Temperature Difference

摘要：

　　When the beam is transmitting,the random fluctuation motion of temperature and pressure of the medium inside the path of transmission will cause the random fluctuation of the index of refraction of the transmission medium.It will form wave front distortion when the beam is transmitting,which is known as the laser transmission turbulence effect.This effect mainly behaves as light intensity flashing,beam drift,phase fluctuation and beam expanding.Using FLUENT software simulate the status of turbulent gas in the environment with small space and large temperature difference (650℃).Verifying the laser transmission turbulence effect can be inhibited by artificial control the distribution of the gas flow inside the flow field,which can optimal the design of the instrument.
