燃油锅炉油滴运动蒸发的数值模拟

Numerical Simulation of Dynamics and Evaporation of Fuel Droplets in the Chamber of Fuel-burning Boiler

采用颗粒轨道法对选配文丘利型油燃烧器的燃油锅炉炉内油滴颗粒的运动和蒸发过程进行了数值模拟。计算结果表明 ,油滴的生存空间基本局限于回流区内 ,油滴不会碰壁。

Dynamics and evaporation of fuel droplets in the chamber of fuel burning boiler with Venturi burner are simulated by employing particle trajectory model. Calculation results indicate that fuel droplets' motion is nearly restricted in the recirculation zone and droplets can't reach the wall of chamber. Dynamics of fuel droplets also indicates that flow field has strong vortex and recirculation.
