Environmental Fluid Mechanics

By Prof.Chunendra K Sahu | IIT Kanpur

Learners enrolled: 451 | Exam registration: 7

ABOUT THE COURSE:

This course is designed to introduce students with the concepts of environmental fluid mechanics. Some examples of such flows include the hot exhaust plumes from industrial chimneys or dust storms during summers, which occur primarily when there is density difference between two fluids in the system due to temperature or concentration gradients. Students will learn about the analytical and experimental techniques that are used to model such naturally driven flows in the atmosphere, in the ocean, or in the subsurface. The course will include the applications of conservation laws of mass, momentum, and energy in deriving necessary solutions and in describing the behavior of environmental flows.

INTENDED AUDIENCE: Faculty, PG students, Senior UG students

PREREQUISITES: Courses on Fluid Mechanics or Hydraulics

INDUSTRY SUPPORT:The industries dealing with remediation of air and water pollution may find this course useful. Moreover, it may be of interest to the government bodies associated with environment related policy making.

He uses both experimental and theoretical approaches to solve the research problems in hand. More details about him and his research can be found at https://sites.google.com/view/cksahu

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: EXAM DATE : April 26, 2025 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 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

Please note that assignments encompass all types (including quizzes, programming tasks, and essay submissions) available in the specific week.

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 Kanpur .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.
