Abstract: Submerged land vehicle (SLV), water operations are limited to amphibian movement. In this paper an existing SLV has been examined in terms of amphibious capabilities. The external flow CFD analysis is commonly used to study the behavior of objects submerged in continuous non static fluids. It aims to determine how efficiently a vehicle can move through the medium and how fluid flow and vehicle motion affect each other in the process. In the present scenario when the SLV is moving under water, the fluid is not confined between wall type conditions such as pipes or confined flow cases. The fluid is free to move around the object and interact only with its external “wet” layer. This means that it is the flow involving the body shape that must be analyzed. By evaluating the pressure and velocity distribution around the SLV, generated by the resistances of the fluid, we can determine the various forces acting on the SLV in different planes and analyze the flow-dynamic stability of the SLV when it is undergoing deep fording.
