CFD Course from University of Florida
I want to introduce one CFD course from university of Florida that Professor S. A. E. Miller recorded from 2020 to 2022. This course introduces students to the general theories, numerical algorithms, and processes of computational fluid dynamics. The main objectives are to understand the pre-process that includes the definition of the problem and grid generation, the solver, and the post-process that includes analysis of the results. The students will learn to interpret computational fluid dynamics results and develop skepticism that is balanced by verification and validation techniques. Throughout the course concepts will be illustrated through the use of one popular commercial computational fluid dynamics computer program. The students will have fundamental knowledge of boundary conditions, grid generation, solvers, turbulence modelling, visualization, numerical methods, and a variety of special topics at the termination of the course. For more information, click on the following link: https://saemiller.com/introduction-cfd/ YouTube Playlist: https://www.youtube.com/playlist?list=PLbiOzt50Bx-kV3Lcn5piPyV9EvpmOybJR

Guess the flow 🌊
My wife and I were hiking today and we stopped by this cute stream/watercourse. Angela thought it’s a nice idea if I post it to reflect on the flow physics with you all 😌 (remember what we said this morning in the virtual coffee? making the community as fun as it is informative). Alright, feel free to share what comes to your mind when you watch this 👇🏼 [let me know if you like that type of content or you think it’s irrelevant]

I was thinking flow through porous media. @Mohamed Sayed , what's the answer? Thanks for sharing the hike! Spring is a wonderful time of year.

@Mohamed Sayed Yes the bright sunshine feels like a dream. I'm in Toronto, Canada. The leaves on the trees are still missing in action :D

Networking in International Conferences
Greetings everyone!! Just a poll regarding which option has a better chance for a student or a professional to increase his/her industry connections when attending international conferences sponsored by some of the big giants of the industry.

I think the having a paper and/or presentation will help you network more with academics. If you want to network with industry, attend the social events, e.g. mixers, and visit their booths/stands. Then, instead of handing out your resume, try to have a meaningful conversation with at least one person from each company, and get their contacts, be it linkedin or email. (Whatever happened to business cards? lol). Send an initial message soon, otherwise they might forget you since confererences are so busy, and they meet so many people. Carry on the conversation after the conference is over, and just be patient. On LinkedIn I am finding that building networks is not so much about receiving favors than it is being friendly with people.

Turbulent Times
In my opinion, CFD is a very vast and interesting subject and tool but the one thing which seems to be very enigmatic is turbulence modelling. My question here is quite simple: 1) How would you explain turbulence and turbulence modelling to a kid? 2) Why do we have so many turbulence models and why is it so hard to model turbulence accurately? 3) From an aerospace perspective, does anyone have ideas of How turbulence works in Hypersonics? Or do we even have turbulence there? Would love to see some interesting answers on the same!

This is a great question, and to be honest, a hard one. Let me attempt an answer to (1). It more or less depends on the kid's age, since their understanding would depend on just how much experience and their up-to-the-present observation of nature. I'd simply explain turbulence as "rough" movement. E.g. when they quickly stir their cup of fruit juice with a spoon, or they shake a bottle of carbonated soda. Then I'd show them this video: https://vimeo.com/873835266 and use it to explain how the rough movement helps things to mix. The artwork in the video is credited to a pair of artists, Marion Pinaffo and Raphaël Pluvinag.

Question/Discussion: How much does it matter which university you study at?
Hey everyone. So in today's virtual coffee, I mentioned that I'm looking to pursue a MSc degree, but the options for fundings/programs are not always that easily available, given one's personal background and resume, you might be needing to go for whatever chance that gets you closer. From your experience, how much does the ranking/reputation of a university or the country you're studying at matter? *Specifically Europe.* And how does that affect one's chance of getting into industry or doing PhD after MSc?

I've been through the US for my MSc and now in Canada for PhD. When applying for MSc I wrongly focused on the university ranking. In my limited experience, it appears that your *thesis advisor* is more important than the institution. The advisor will have a professional network which you can then leverage to pursue Ph.D. options. May I also naively add that it may not be necessary to do a Ph.D., especially if you plan to work in industry.

@Mostafa Seif You're most welcome. This is just my personal experience, and you might have an entirely different one.
