Online CFD and Hydrodynamics for Ships Training


Computational Fluid Dynamics (CFD) technology is now a well-established design tool for ships to predict accurately its performance and is gradually replacing towing tanks. With the right CFD tools,
every aspect of the vessel design and performance can be investigated virtually, well before the vessel goes into production. The advantage for the maritime industry from CFD analysis is
extensive. The benefits are far greater, as compared to other industries. Commercial
ship vessels in particular can benefit hugely by using this technology. The syllabus will include Introduction to CFD, Numerical modelling of curves and surfaces, Discretization of ship hull form,
Fluid flow dynamics around ships and submarines, Turbulence modelling, Finite
volume method as applied to ship flows, Numerical method for computing propeller thrust/ torque.
The course is designed in such a way that at the end of the lectures, the person will have a very broad understanding of the application of CFD techniques for ship design.


Engineers and scientists involved in the design of ships and ship systems. Personnel from ship management companies, oil companies, classification societies and ship builders will benefit from attending this course. The course is innovative in both content & structure with a careful balance
of theory & practice.

Dr O.P Sha received his B.Tech. (Hons.) degree in Naval Architecture from the
Indian Institute of Technology, Kharagpur in 1980; M.Sc. in Ship Production
Technology from the University of Strathclyde, Scotland, United Kingdom, in
1982; and Ph.D. in Engineering from the Indian Institute of Technology, Kharagpur
in 1996. Presently, he is a Professor in the Department of Ocean Engineering and
Naval Architecture. He was the Head of the Department of Ocean Engineering and
Naval Architecture from October 2010 to September 2013 and subsequently the Dean
of Continuing Education from October 2013 to September 2016 at the Indian Institute of
Technology, Kharagpur. He teaches a wide variety of subjects at the Institute and his
main areas of interest include ship design and production, CAD/CAM and high
performance vehicles. He is currently involved in a number of sponsored research
and industrial consultancy projects with DRDO, Indian Navy, Ministry of Shipping,
Garden Reach Shipbuilders and Engineers Limited, Cochin Shipyard Limited, L&T
Shipbuilding, Kolkata Port Trust, IWAI, SHOFT Shipyard, etc. He is the Chairman,
Hydrodynamics Panel of Naval Research Board, Govt. of India. He has a number of
publications in the area of Ship Design and Production and has guided a number of
doctoral and postgraduate students. He has been entrusted by the Sagarmala Cell of
Ministry of Shipping and IIT Kharagpur to head the Centre for Inland and Coastal
Maritime Technology (CICMT) at IIT Kharagpur where the country’s first
shallow/deep water seakeeping and manoeuvring basin for ship-model testing
will be set up. This will provide impetus to research and development in the area of
inland and coastal maritime technology.

Dr. Vishwanath Nagarajan is an Associate Professor in the Department of Ocean
Engineering and Naval Architecture, IIT Kharagpur. His broad area of research is ship
and underwater vehicle dynamics and fluid dynamics. He is involved in teaching several
subjects for under graduate and post graduate students. Dr. Vishwanath graduated from IIT
Kharagpur, B.Tech (Naval Architecture), in 1995. After graduation, he joined as a Naval
Architect in The Shipping Corporation of India Ltd., Mumbai. Here he was involved in
ship building, ship construction, and ship maintenance work. During this time, he got
Japanese Government Scholarship (Monbukagakusho) to do Masters and PhD at
Osaka University, Japan. After completing PhD, he worked for a short time as a Post
Doctoral researcher in Pusan National University, South Korea. Thereafter, he
joined IIT Kharagpur in 2009 as faculty. He has supervised numerous undergraduate and
postgraduate research projects, besides guiding Ph. D. students. He has published
