Fluid Mechanics Lesson Series - Lesson 01B: Classification of Fluid Flows
In this 18-minute video, Professor Cimbala discusses various classifications of fluid mechanics:
1. Viscous vs. inviscid regions of flow
2. Internal vs. external flow
3. Compressible vs. incompressible flow
4. Laminar vs. turbulent flow
5. Steady vs. unsteady flow
6. One-, two-, or three-dimensional flow
Also defined are the no-slip condition, viscosity, turbulence, Mach number, and speed of sound.
This video incorporates material from Sections 1-3 and 1-4 of the Fluid Mechanics textbook by Cengel and Cimbala.

Thanks. Let's hope more people find my channel.

@@johncimbala I just did! Currently studying from this wonderful collection as I’m about to start my master’s degree in energy. I have no background in fluid mechanics so this is the time of my life. Thank you for this opportunity!

If I ever were to teach Introductory Fluid Mechanics, I would use this book with these videos!

I really like how you are clearly defining all the key terms, in an understandable way, while still being specific. Question: This whole "Fluid Mechanics"-playlist is around 84 videos long, covering quite a bit of material... how much would the material in the playlist be equivalent to in terms of course-size in a university? (For example, in my country we have 60 ECTS points per calender-year, and some of our courses is 5 points, others 10, and a few is 20 points in terms of workload).

@johncimbala 10 месяцев назад

These videos correspond to my entire undergraduate fluid mechanics course at Penn State, which is one semester, 3 credits. During class time I go over the lessons briefly and then do extra example problems. Thank you for kind comment about my videos.

@mertkabadayogullar6479 Год назад

could you solve more examples? or another serie which has just example solutions from your book

@johncimbala Год назад

some of them are just examples - like Lesson 08G

@omaralani1105 5 месяцев назад

Again, thank you for your great series. In Munson's textbook (I use three to four textbooks to help me understand), it says that one-,two-, three-dimensional flow depends on the number of components (u,v,w) of velocity and not the number of spatial coordinates. For example, would this be a one- or two-dimensional flow? V=(6y)i+(3)j As per my understanding, it should be a 1D flow as it only depends on a single spatial coordinate (the y-position). There are two directions to the flow but it only depends on a single spatial coordinate.. I would appreciate it if you could clear up my confusion.

@johncimbala 5 месяцев назад

That is a tricky one. In your example, the y component of velocity is constant. So, you could do a Galilean transformation by moving up with the flow (at speed 3). Then you would see u=6y and v =0 from this moving reference frame. So, I would call this one-dimensional. By the way, thank you for your comment.

@Ra-vq2jp 9 месяцев назад

is this series for chemical engineering fluid mechanics? and is it enough to fully understand this course?

@johncimbala 9 месяцев назад

I teach in the Mechanical Engineering Department, so the series is geared towards MEs. However, civil and chemical and aerospace engineers also find the series helpful.

@mujahidkhichi9527 5 месяцев назад

Such an outstanding channel.❤ Could you please suggest a book for the subject. Student of Mechanical engineering.

@johncimbala 5 месяцев назад

Of course. The best fluid mechanics book is the one I co-authored, on which this video series is based. :) Cengel and Cimbala, McGraw-Hill, Fluid Mechanics: Fundamentals and Applications.
