Computational Fluid Dynamics needs a thorough understanding of fluid flow and heat transfer. Understanding of fundamentals plays a crucial role in problem definition and interpretation of the results. Initial few months will be devoted to lay the foundation stones. Once the fundamentals are firm, advance topics will be covered along with training on commercial software packages. The course is structured to cater to the industrial requirements. The course syllabus is formulated by considering industrial needs and inputs from various working professionals and IIT faculty.  

Program Structure

The curriculum is distributed in five levels, viz. foundation, core, advanced topics, industry specific training and product specific training.

The training program consists of a number of conventional lectures which includes fundamental, core and advanced topics. This includes industry specific modules to give hands-on experience to students on specific industry problems. This also includes product specific modules so that the students will get experience on widely used software packages in industry. To bridge the gap between theory and practice, students will undertake a project at the end of the course.
