High Performance Computing Laboratory (CFD Lab earlier) at the Aerospace Engineering Department of I.I.T. Kanpur - started by Prof. Tapan K Sengupta, has been an active place of research right from its inception in 1990. The emphasis of research is on developing high accuracy computing methods to aid in bridging the gap between theoretical and computational fluid dynamics and heat transfer.
