This course is introductory in nature and expected to impart firsthand knowledge of CFD. It is mainly aimed for senior undergraduate students/ first year post graduate students in Aerospace, Mechanical, Applied Mechanics, Applied Mathematics and allied streams. It is concerned with application of numerical methods for solving conservation equations of fluid dynamics. The subject will be taught with the objective of motivating students to develop their own computer codes. With a long experience of teaching both introductory and advanced courses in CFD to UG, PG and PhD students, I strongly feel that this is the best way to learn CFD.
INTENDED AUDIENCE :Aerospace Engineering/ Mechanical Engineering/ Applied Mechanics Applied Mathematics and allied disciplinesPREREQUISITES :Basic course on Fluid Mechanics and Numerical MethodsINDUSTRIES SUPPORT :This introductory course on computational fluid dynamics (CFD) could be appropriate for new recruits in aerospace research laboratories like NAL, DRDL, ADA, ADE, HAL and private industry. Additionally, large number of industries in Mechanical engineering domain dealing with thermal and fluid mechanics applications would find it useful.
