Numerical Simulation On Airflow In Firebox Of Plateau Oil-fired Air Heater

Plateau oil-fired warm air heater is an ideal warm equipment of supplying warm for troop tent in plateau for it's small volume and flexibility. There are two methods to development Plateau oil-fired warm air heater. One is experimentation; the other is numerical simulation.This paper aims to numerical simulation to research the characteristic of warm air heater. First, we simulate the firebox through realization k-e turbulent model. If experimentation data match to simulated data, we consider the physics model and turbulent model we establish is valid. Second, we development the influence of flamethrower shape, root air, the obliquity of spin vane and block heat board for the air current in the firebox by simulating them through two phases calculate. In this case, we take standard k ?s turbulent model. Through simulated results, we can receive ideal flamethrower shape, root air, and the obliquity of spin vane so that plateau oil-fired warm air heater ignition easily, flame is stabilization and burn sufficiency. In addition, these simulated results can provide engineers with a certain basis to design air register, and establish foundation for the further studies on the simulation under hot conditions.
