Two-Phase Flow With Phase Change In Conventional And Miniature Channels

By Prof. Manmohan Pandey   |   IIT Guwahati
Learners enrolled: 49
Gas-liquid flows occur in various industrial applications, such as power generation, refrigeration, oil & gas production, and thermal management of future electronic devices. In this course, one-dimensional models of two-phase flow with and without phase change will be introduced. Methods of pressure drop prediction for adiabatic gas-liquid flow as well as flow boiling will be discussed. Special methods for pressure drop modeling of two-phase flow in miniature channels will also be introduced.

INTENDED AUDIENCE: Postgraduate and final year undergraduate students in mechanical and chemical engineering;
                                        engineers working in the industry and R&D labs.
PREREQUISITES:          Undergraduate level background (first course) in fluid mechanics, thermodynamics and heat transfer.

Course certificate

The course is free to enroll and learn from. But if you want a certificate, you have to register and write the proctored exam conducted by us in person at any of the designated exam centres.
The exam is optional for a fee of Rs 1000/- (Rupees one thousand only).
Date and Time of Exams: 
29 April 2023 Morning session 9am to 12 noon; Afternoon Session 2pm to 5pm.
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 Guwahati. 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.
