This paper aims to present k-epsilon turbulent model to describe the gas flow in motorcycle carburetor, in accordance with the working principle of the carburetor and based on the Navier-Stokes equation. With nonstaggered grid SIMPLE algorithm in an Eulerian frame of reference, the gas phase equations are solved. On the basis of the evaporation of a single droplet, the liquid phase calculations are performed in a Lagrangian frame of reference by means of four-stage Runge-Kutta algorithm. Gas-liquid two-phase is coupled with PSIC algorithm. Finally, numerical simulation of flow in the carburetor is carried out as the throttle is under the economical operating condition.
