Introduction to CFD

By Prof. Arnab Roy | IIT Kharagpur

Learners enrolled: 2842

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 disciplines

PREREQUISITES : Basic course on Fluid Mechanics and Numerical Methods

INDUSTRIES 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.

IIT Kharagpur

1. I am currently working as Professor at the Department of Aerospace Engineering, IIT Kharagpur. The above weblink provides my research details. 2. I have taught various courses covering Aerodynamics, introductory and advanced courses in CFD, Wind Tunnel Design and Testing as well as a few courses in Aerospace Propulsion at IIT Kharagpur to UG/ PG and PhD students.On almost all occasions I have received an overall student feedback rating between 4 and 5 (on a scale of 5). In all, I have about 16 years teaching experience at UG and PG levels combined. 3. My research interests include computational and experimental fluid dynamics. I am also involved in aerospace propulsion research. I have undertaken and executed projects for different organizations like AOARD (Japan), Boeing (USA), AR&DB, DLJ-DRDO, RDSO, ISRO, DST etc 4. I have delivered several CFD related invited lectures at GE Aviation JFWTC, Bangalore (2019); CFD Workshop, BITS Pilani Hyderabad campus (2016); 13th Aeronautical Society of India Annual CFD Symposium at IISc Bangalore (2011),Indo US INDUS-MAV Workshop at Bangalore,organized by NAL and ADE Bangalore (2009) etc.
