  • Based on computational fluid dynamics method,airplane in idle condition was studied in conjunction with heat transfer in a nacelle.And different radiation computation methods including spherical harmonics,discrete ordinate and Monte Carlo method were adopted to simulate thermal radiation.The result shows that coupling effect of radiation and convection is obvious.In addition,compared with the simulation result of pure convection,nacelle ambient temperature predicted by coupling way is 7%~30% higher.While selective absorption of air under infrared radiation is taken into account,the ambient temperature rises further.Thus the effect of thermal radiation should not be ignored to simulate nacelle hear transfer in ground condition.
