Adiabatic Two-Phase Flow and Flow Boiling in Microchannel

Adiabatic Two-Phase Flow and Flow Boiling in Microchannel. Instructor: Prof. Gargi Das, Department of Chemical Engineering, IIT Kharagpur. The course deals with the numerical solution of equations governing fluid flow and would be of interest to engineers and scientists - both aspiring and professional - with chemical/ mechanical/ civil/ aerospace engineering applications. In all these fields, one needs to deal extensively with fluid flow related phenomena and one needs to resolve flow-related features of the processes and equipment. Although the equations governing fluid flow have been formulated more than 150 years ago, it is only in recent years that these are being solved in the practical applications in which the flow occurs. The course deals with the basic techniques that enable the numerical solution of these equations. (from nptel.ac.in)
