【Abstract】 The κ ε two equation model and wall function were chosen to simulate the turbulent flow and temperature field of normal marine exhaust system numerically. After experimental tests the self simulation principle was used to develop the numerical simulation method to physical device. The Hottel method was used to calculate the distribution of infrared radiation after establishing the view factor between viewpoint and device.更多还原
