A three-dimensional computational analysis program of gas-liquid two-phase flow is developed in order to simulate fuel flow in the intake menifold of an automobile fuel supplier. This program considers physical models as follows: (a) movement of fuel droplets and their deposition on the manifold wall; (b) temperuture change and evaporation of the droplets: (c) evaporation of fuel deposited on the wall: (d) transport of fuel vapor evaporated from the wall: and (e) force of the droplets' influence upon air. Calculated results show that all fuel droplets injected from the fuel injector deposit on the wall, and when the wall temperatures are 20℃ and 80℃, 95% and 37% of the injected fuel flow into the cylinders in the state of liquid film, respectively. The remaining fuel flows into the cylinders as vapor.
