According to the applicability conditions for three types of internal solitary wave theories including Korteweg-de Vries, extended KdV and Miyata-Choi-Camassa, the double push-pedals wave-generating method, the velocity-inlet wave-generating method and the mass source wave-generating method were developed y in a two-layer fluid of finite depth. Series of numerical simulations were presented to compare the results and efficiency of the three wave-generating methods. Results showed that even though all three methods can generate internal solitary waves, the velocity-inlet method and the mass source method were better than the double push-pedals method in terms of numerical simulations. The efficiency of simulation was the highest for the velocity-inlet method, followed by the mass source method, and the lowest for the double push-pedals method.
