A two-dimensional model of gas-liquid tow-phase flow was developed in order to simulate flow in a carburetor. it is assumed that small particles of dispersed fuel are transferred at the same velocity as air flow. The air-fuel mixture, which is assumed to have volume-averaged density, is numerically calculated by the fluid in cell method (a finite difference method) in accordance with conservation laws of mass, momentum and energy. It was confirmed that minimum pressure and maximum velocity were shown at the narrowest point of the top venturi in the air single-phase flow analysis. in the two-phase flow analysis, fuel flow was decelerated in the central region of the carburetor and was accelerated in the periphery.
