Another great lecture mr Bejan! Keep it up
Thank you! Great lecture
Do you have any book or chapter regarding conduction and convection in the porous and permeable medium, e.g. petroleum rocks?
Dear Professor, Your books are awesome! I used your Black Book of Convection Heat Transfer during my master's course, and the approaches were complete. I confess that the part of external flow with turbulence was challenging :D
Thank you for posting these videos! I had my first Thermodynamics class 27 years ago, and Prof. Bejan’s book made me fall in love with it. He even gave a lecture once at my University in Medellin, Colombia (Universidad Pontificia Bolivariana). Getting to see this now made my day!
Thank you!
Sir first of all thank you. I really enjoy your lessons and would love to see more of it. If you can upload videos which you explain the concepts furthermore it would be much appreciated.
This is so elegant! Thank you for that graphical representation -- easy to remember, helpful too.
Excellent presentation! Your in-depth exploration of mass and momentum conservation principles, combined with insightful examples, provided a profound understanding of the subject. The clarity in your explanations and the methodical approach truly elevate this content. Looking forward to more high-level discussions!
Thank you
I wish I could attend this class just to speak up
11:47 I feel like just fundamental constructal physics helps here (to think less). It’s a long fast channel and it’s dumping heat at whatever interval perpendicularly (short slow channels).
Thank you very much Professor !
Bună ziua! Aveți și un curs unde putem participa? Cum se poate aplica acesta teorie în afaceri? Mulțumesc mult
Great lecture sir
3 day ago I know about you from my prof. From IIT BHU. I ordered your book from Amazon.
Things get simpler when explained by person who masters them. Thanks you for this course.
Great teacher and researcher
go with the flow
Thank you Dr. Bejan!
Decipline is a distinct body of knowledge That has very few rules that underpin great great progress. A group of obversations that repeat themselves in the same way innumerable times is one distinct phenomenon. Science comes from one phenomenon. One Law. The Law of Conservation reveals the difference between potential and kenistetic power. Irriversability is the one way nature of flow. Everything, by itself, goes from high to low. Flowing by itself, not from external interventions. The phenomenon (Occurrence) of flow configurations is The Constructal Law. To predict, how something should or will be, is called theory. To observe is "to describe, then explain" is called emperism. These are distinctly different. Evolutionary design preceded science as it's known today.
Great lecture. It's always a pleasure. Best wishes.
Beautiful professor
It is interesting to consider freedom as the ability to modify factors rather than specific outcomes. Thank you for this lecture 🙏
Like for the video ! Many regards from Galați !
Amazing... Huge Respect. Sir.... ! 🙏Hope to see you in CLC. @Bejan
Great session. Just the right balance of Geometry, humor & philosophy. Thanks Prof. Bejan.
The One and Only!
Like pentru video Don Profesor ! Multă sănătate !
Dear Professor Adrian Bejan Could you make a video splaine your postuled about the 4th Law of Thermodynamic ? This theme, looks very interesting! Best Regard
Congratulations Prof. Adrian. It is a superb lecture!
Felicitãri și mulțumiri pentru video ! Multe salutări din Fredrikstad ( Norvegia ). ( și eu sunt născut în Galați pe timpurile de demult... )
Hi Professor Bejan. In your left shoulder, have a diploma looks like an UFPR diploma, do you had studied in Brazil? Congratulation for your videos!
If only more schools and teachers were like this!
Not just luck and America, also work and genius.
I feel like I haven't cited related works by Dr. Bejan enough. In part there are different incentives facing each person or institution, also we have some irrationality and uncertainty.
Thank you for another amazing video. Explains a ton that the rest of us should try to understand and use. Would make the world a better place!
Exploring the physical constructal law within social systems may help expedite the evolution of global civility.

Thanks for sharing all the content in your channel Professor Bejan.
Very interesting and already based on the "facility to flow" - Adrian BEJAN Professor's constructal law formulation.
Prof. Adrian Bejan, he is the greatest person in my research field. I hope he is always healthy and in a good shape. Miss you soooo much, my dear professor.
Enlightening !!
Professor Bejan is always inspirational, I recall the times I spent in his laboratory and one message change the career of many as mine is I am quoting from him was "Walk with open eyes!". Yes, we should observe the phenomena to understand the physics behind it, and then we can improve the current state of art. Random solutions may work for awhile but they are not the best! I totally agree university should teach how to think independently and question even the concepts taken granted. Otherwise there would be no progress. We need more people like Prof Bejan for students to begin thinking freely without any obstacle. Freedom and discussions are good to improve state of art.
Dear Professor Bejan, I agree with everything you have presented. In particular, I found it interesting that you highlight the fact that we need to have the audacity to do something different and better. I am a professor here at the Federal University of Paraná and I have the pleasure of working side by side with Professor José Viriato Coelho Vargas, your former doctoral student. Thanks to Professor Vargas, I got to know about your work and constructstal theory. Today, the focus of my professional practice is to integrate research and teaching with innovation. We created a methodology called 'Startup Experience' to encourage our students to create innovative solutions for society. I hope that soon some student will apply constructal theory in one of these initiatives. Greetings from Curitiba - Brazil.
Students under Bejan’s tutelage, in our postmodern time, may find their way in other universities throughout the world exploring the Constructal paradigm relative to reason and ethics in the evolution of global civility. My UA-cam channel gives a constructal social example, inviting students and scholars across the social and philosophical spectrum, possibly opening new doors in research.
