In this study, numerical investigation of spatial developing breaking air-water interface turbulent flow with heat transfer was conducted. The Reynolds number is about 3300 based on the gas layer height and the free stream velocity. The computational domain consists of a driver region used for Direct Numerical Simulation (DNS) of single phase gas flow of turbulent boundary layer and a main region for the two phase flow simulation. Grids number is 128×82×256 (in the driver region) and 256×157×256 (in the main region) in streamwise, vertical and spanwise directions, respectively. In the main region, the calculation of wind-driven turbulent flow was carried out by means of the direct numerical solution procedure (MARS method) for a coupled gas-liquid flow.
