To explore mass source method for numerical wave generation of internal solitary waves, we adopted two point-typed mass sources as the excitation point sources, and placed them in the middle of the upper and lower layers of two-layered fluid to generating internal solitary waves. The equations and expressions of the source terms were derived. Based on the Navier-Stokes equation in combination of the Kd V and e Kd V theories, a mass source method for numerical simulation of internal solitary waves was developed with commercial software FLUENT, and the generation of internal solitary wave in the simulation was analyzed. Comparison between theoretical and experimental outcomes showed good agreement in waveform, wave height, and horizontal velocity, indicating that this mass method is feasible, quick, and efficient.
