Adiabatic Two Phase Flow and Flow Boiling in Microchannel

By Prof. Gargi Das   |   IIT Kharagpur
Learners enrolled: 908
The course is designed to provide the participants a basic idea of multiphase flow and flow boiling heat transfer in microchannels. This is pertinent in the current trend of miniaturization as a means of process intensification and is frequently encountered in pharmaceutical and fine chemical industries, microchip cooling and flow through porous medium. The present course discusses the underlying fluid mechanical principles governing multiphase flow in micro vis-a vis macro domain, influence of operating parameters on flow morphology, different experimental techniques and pattern based analysis relevant in this scale as well as the uniqueness of flow boiling heat transfer in microchannels.

Registration url: Announcements will be made when the registration form is open for registrations.
The online registration form has to be filled and the certification exam fee needs to be paid. More details will be made available when the exam registration form is published. If there are any changes, it will be mentioned then.
Please check the form for more details on the cities where the exams will be held, the conditions you agree to when you fill the form etc.


Average assignment score = 25% of average of best 3 assignments out of the total 4 assignments given in the course.
Exam score = 75% of the proctored certification exam score out of 100
Final score = Average assignment score + Exam score

YOU WILL BE ELIGIBLE FOR A CERTIFICATE ONLY IF AVERAGE ASSIGNMENT SCORE >=10/25 AND EXAM SCORE >= 30/75. If one of the 2 criteria is not met, you will not get the certificate even if the Final score >= 40/100.

Certificate will have your name, photograph and the score in the final exam with the breakup.It will have the logos of NPTEL and IIT Kharagpur .It will be e-verifiable at nptel.ac.in/noc.

Only the e-certificate will be made available. Hard copies will not be dispatched.

Once again, thanks for your interest in our online courses and certification. Happy learning.
