Multiphase Microfluidics

By Prof. Raghvendra Gupta   |   IIT Guwahati
Learners enrolled: 23
ABOUT THE COURSE:
With the advancement in manufacturing technology in past few decades, the trend towards miniaturization has accelerated in several industries. In chemical process industries, the viability of compact heat exchangers, microreactors for process intensification is being explored because of small diffusion lengths, high interfacial area density and relatively safe operation. Most of these equipments involve multiphase flows and their design requires a fundamental understanding of heat, mass and momentum transport in multiphase flow in microchannels. This course is aimed at introducing the students with the fundamental principles as well as recent developments in the area of multiphase flow at the small scale.

INTENDED AUDIENCE: 1.Postgraduate (M Tech and PhD) and final year undergraduate student from chemical, mechanical engineering disciplines.
2.Industry practitioners from chemical micro-processing, electronics cooling and biomedical industry
Course is primarily a PG course but can be taken by third/final year students as well.

PREREQUISITES: A basic course in Fluid Mechanics

INDUSTRY SUPPORT: Thermax, General Electric, Syrris, Blacktrace/Dolomite

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.

CRITERIA TO GET A CERTIFICATE

Average assignment score = 25% of average of best 6 assignments out of the total 8 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.
