Infrared characteristic of marine exhaust eductor system

The kappa-epsilon two-equation model and wall function were chosen to simul ate the turbulent flow and temperature field of normal marine exhaust syste m numerically. After experimental tests the self-simulation principle was u sed to develop the numerical simulation method to physical device. The Hott el method was used to calculate the distribution of infrared radiation afte r establishing the view-factor between viewpoint and device.
