We had proposed a propulsive nozzle for a ship with a pulse detonation engine. The high-pressure wave generated by the PDE is used as a source of a drive. In addition to the experimental analysis, we try to analize the flows inside the propulsive nozzle numerically. The new two particles model of a thermal finite difference lattice Boltzman method is presented for simulating gas-liquid two phase flows like air-water flows. The model enables us to control the sound speed of each phase by introducing the macroscopic effects to the FDLBM as the intermolecular force. It is confirmed that the Rankine-Hugoniot relation of ideal gases is satisfied in the gas phase, the sound speed agrees with the macroscopic equation, and the incompressible effect is given to the liquid phase.
