Research project: Prediction of hydrodynamics characteristics of naval vessels

Currently Active: 

Power prediction is a vital input to the concept design of new vessels. Accuracy of prediction is often the most critical factor for fast speed boats as it helps balance between resulting over-design and acceptability of the vessel at a later stage. CFD as a tool is finding acceptance in the industry, due to its flexibility and reduced execution-time over the traditional model testing, and is used here to estimate the resistance, trim and sinkage for three high speed vessels.

Performance prediction is an important part of vessel design. Common methods used for predicting planning hull performance include empirical equations and model tests. Model tests are usually expensive, while empirical equations are often applicable to similar hull types. In this work, CFD is used as an alternative prediction tool for high speed planning vessels. A consultancy work for Larsen & Toubro, India on 3 vessels in proposal design stage to estimate resistance and floating aptitude using CFD has also been done, September/October 2012.
