In this paper the moving of an Autonomous Underwater Vehicle (AUV) in the tube that move by force of high pressured air was studied. There are a high pressure capsule beside of tube and when the valve between the capsule and tube opened the pressured air flow in tube and the AUV launched out. The modeling is two dimensional axisymmetric and single phase. We used the fluent software and the UDF for modeling and used the RSM model for the turbulent modeling. The variation of pressure of capsule and effect of initial capsule pressure on the velocity profile of the AUV investigated.
