Interfacial Fluid Mechanics

By Prof. Harish N Dixit   |   IIT Hyderabad
Learners enrolled: 218
About the Course : 
This course will introduce the student to the wonderful and beautiful world of interfacial fluid dynamics. These are fluid systems dominated by surface or interfacial tension. First half of the course will deal with many examples of fluid systems dominated by surface tension followed by a detailed discussion of the relevant governing equations and boundary conditions. Static systems – shape of a meniscus, shape of a drop, etc will also be discussed. Second half of the course will focus on specific fluid systems, viz. thin films, shape of a falling jet, coating flows, well-known instabilities like the Rayleigh-Taylor and Rayleigh-Plateau instabilities, Marangoni effects, contact lines, etc. Throughout the course, theoretical concepts will be related to real-world examples.

PRE-REQUISITES : Students should have completed a basic course (UG or PG level) in fluid mechanics and should be comfortable with multivariable calculus

INTENDED AUDIENCE
Students in Chemical Engineering, Mechanical Engineering and Engineering Physics; Industry personnel working in the broad area of multiphase flows.

INDUSTRY SUPPORT : Industries specifically focusing on problems studied by Chemical Engineers such as problems involving two-phase flows, interfaces with surfactants, wettability of surfaces, etc. Example industries include Whirpool Corporation, Saint Gobain, Unilever, etc.

Instructor bio

Prof. Harish N Dixit

IIT Hyderabad
Dr. Harish N Dixit is an Associate Professor at the Mechancial & Aerospace Engineering department at IIT Hyderabad. He completed his Ph.D. at the Jawaharlal Nehru Centre for Advanced Scientific Research in Bengaluru and was subsequently a postdoctoral fellow at the University of British Columbia in Canada. He has been a faculty at IIT Hyderabad since October 2013. He works in the broad area of interfacial flows with specific focus on problems related to interaction of drop and bubbles with interfaces as well as the dynamics of a moving contact lines. His group employs a combination of theoretical, experimental and numerical tools to unravel novel physics in interfacial flows.

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: 30 October 2022 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.

CRITERIA TO GET A CERTIFICATE

Average assignment score = 25% of average of best 8 assignments out of the total 12 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 Hyderabad. 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.
