Coastal areas are among the most vulnerable of all regions to global climate change which include global warming, rising sea levels, increasing sea-surface temperatures etc. Also rise in the foreign insurgency through the oceans is forcing the nations to enhance the maritime surveillance & security capabilities. To check coasts from climate change, foreign insurgency, reconnaissance and for surveillance, search & rescue operations continuous monitoring of the shore & the seabed is essential. Replacing the human divers with underwater vehicles with suite of sensors would ensure the continuous observation of the seashore & sea bed. An unmanned underwater vehicle (UUV) is a small submarine, which is normally deployed for various dangerous underwater tasks that include search and rescue operations. Researchers at various institutes around the world have made UUV�S of different hull & control plane shapes for different applications, each of which has advantages & disadvantages. The main objective of the present project is to identify the right combination of the hull & control plane shapes by performing fluid flow simulation over various hull & control surfaces of UUV separately & then integrating them. After the integration, position of control surface over the hull is also varied to study their effect on hydrodynamic characteristics. In this Study flow analysis is performed on hull shape modeled with the dimensions of MAYA AUV which was developed at the National institute of Oceanography Goa India with various nose shapes and the best suitable nose shape of the hull is chosen from the simulation results.
