The merger of two disk galaxies containing gas clouds and stars is simulated numerically to examine the effects of the merger on gas dynamics and star formation. The three types of particles in the simulation include stars, gas clouds, and OB stars; the OB stars are newly formed stars at the center of mass of the two colliding stars. The simulation, involving two disk-galaxy models in the isolated state which merge, shows that the cloud-cloud collision rate is repetitively increased by about 10 times over a repetition period of 10 to the 8th years. The orbital motion of two dense gaseous cores, formed at the centers of the two original galaxies, causes the repetitive increase. The cores eventually orbit each other at the center of the merged system, and the cloud-cloud collision rate is inversely proportional to the distance between the cores. This result can explain the varying star-formation efficiencies of observed merging galaxies.
