Start Course

In many industrial systems it is critical to know component and material temperatures. In thermal application this becomes a major design issue. In such applications CFD is used as a tool for design assessments. Typical design issue for example is to understand the overall heat transfer coefficient in case of car radiator. Problems like predicting the maximum or minimum temperatures in case of gas turbine, chemical reaction vessels and food ovens. Problems can be to know how the temperature variation takes place in case of aircraft walls. Engine cooling, vehicle internal thermal comfort and many such critical design parameters are related to combined analysis of fluid flow and heat transfer using CFD. 

To perform such heat transfer dominated simulations one needs additional knowledge and implementation skills of thermal modeling techniques like selection of conduction schemes, material property functions and radiation models. One has to go one step ahead of simpler CFD analysis to learn all such advanced thermal modeling techniques. In this course you will learn all the complex, specialized procedures and models which are used to simulate heat transfer dominated phenomenon in engineering and nature. The course will provide a deeper understanding of CFD as a design tool to analyze complete physics of a real world problem by real time coupling of a fluid flow and heat transfer problem.
