Показать описание
MEC516/BME516 Fluid Mechanics I: A Fluid Mechanics Final Exam question on solving the Navier-Stokes equations (Chapter 4). The velocity and pressure fields are calculated for a gravity-driven liquid film on an inclined plate. This unique aspect of this problem is the no shear stress boundary condition at the top of the liquid film.

I wish your channel had been available in the early 2000's, when I took Transport Phenomena in college (not even YouTube was available).

Hi prof, I find your videos extremely helpful. Right now I'm struggling with Fluid Mechanics especially on Navier Stokes and Boundary Layer Theory. May I ask your kindness to upload more videos solving problems of Boundary Layer Theory and Navier Stokes?

Is this something from an engineering course? Seems too applicable to be physics. If it is engineering, which year of study is it?

i have a question, does the order of integrating and applying boundary conditions matter? I mean if I integrate two times right away and then solve the constants I seem to get a different result than when I integrate, boundary, integrate and boundary do...

These videos are great. Your website is even better. Thank yout for this content.

Do you plan to add more topics to the website in the future? Pipe flow, sinks and sources, etc.?
