Fluids in Motion: Crash Course Physics #15
Today, we continue our exploration of fluids and fluid dynamics. How do fluids act when they're in motion? How does pressure in different places change water flow? And what is one of the motion annoying things about filming outside on a nice day? I'll give you a hint on that last one... it's lawnmowers.
In this episode of Crash Course Physics, Shini talks to us about how fluids in motion are really, really, REALLY powerful things.

Understanding Bernoulli's Equation
The Curiosity Stream and Nebula bundle is no longer available, but you can still sign up for Nebula and get acess to my bonus videos - use this link for 40% off! https://go.nebula.tv/the-efficient-engineer.
Bernoulli's equation is a simple but incredibly important equation in physics and engineering that can help us understand a lot about the flow of fluids in the world around us. It essentially describes the relationship between the pressure, velocity and elevation of a flowing fluid.
In this video we'll look at how the equation can be used, and we'll explore a range of different applications.

Fluid dynamics feels natural once you start with quantum mechanics
This is the first part in a series about Computational Fluid Dynamics where we build a Fluid Simulator from scratch.
We highlight the Microscopic Perspective on Quantum Mechanics, Molecular Dynamics, and the Kinetic Theory of Gases that underlies and justifies Fluid Simulation Formulations in the first place.
The Microscopic Perspective provides the ground for the next part where we focus on the Macroscopic Perspective with concepts such as Pressure, Viscosity, Temperature, and Flow Velocity as well as its evolution with time.

Bernoulli's principle
The narrower the pipe section, the lower the pressure in the liquid or gas flowing through this section. This paradoxical fact, following from the law of conservation of energy, is called the Bernoulli principle or law.

Why Does Fluid Pressure Decrease and Velocity Increase in a Tapering Pipe?
Bernoulli's Equation vs Newton's Laws in a Venturi
Often people (incorrectly) think that the decreasing diameter of a pipe correlates to a smaller volume and thus higher pressure. But the ideal gas law has no place in INCOMPRESSIBLE fluid flow.
Others try to explain the decrease in static pressure using Bernoulli's Principle, however, unless you have a VERY good handle on Bernoulli's, that is mostly a self supporting argument.
Back all the way up to Newton's 2nd Law to understand why there is a decrease in pressure in a pipe taper.

FluidX3D - A New Era of Computational Fluid Dynamics
With slow commercial #CFD software, compute time for my PhD studies would have exceeded decades. The only way to success was to master #GPU programming, write my own CFD solver from the ground up and turn runtime to days. Now a 10 billion cell simulation (like in the video) runs over night on an 8-GPU server, visualizing hundreds of TeraByte with my #OpenCL graphics engine.
I have since published my source code to make this powerful tool freely available to other researchers/students/hobbyists. Today #FluidX3D the most popular CFD code on GitHub with 1.6k Stargazers: https://github.com/ProjectPhysX/FluidX3D
Thanks to the people at Jülich Supercomputing Centre for letting me test their hardware!

Pavol Dobryakov turbulent simulations: https://paveldogreat.github.io/WebGL-Fluid-Simulation/
I got into turbulent flow via chaos. The transition to turbulence sometimes involves a period doubling. Turbulence itself is chaotic motion, it is unpredictable and sensitively dependent on initial conditions. What surprised me is all the ways turbulent flow is useful to us. It is diffusive, meaning it causes mixing. This is useful in jet engines or rocket nozzles (which Destin studies) and is important to achieve in microfluidic devices, which are so small that turbulent flow is actually difficult to achieve. Turbulent flow can energize a boundary layer, which is important to maintain flow attachment over a wing, maintaining lift and delaying stall. Similarly a turbulent boundary layer over a golf ball reduces pressure drag allowing golf balls to fly further. This is the reason for the dimples on golf balls. Flow transitioning to turbulence in the wake of a bluff body can create periodic vortex shedding. This beautiful phenomenon can be seen in the von Kàrmàn vortex street in clouds viewed from space. Turbulence is everywhere, in the air currents in a room, in your aorta, in the breaths you exhale, in oil pipelines and water pipes, in the flow over cars and ships and planes. Animals have evolved for it (like dead fish swimming up stream) and we have engineered our environment, our planes and golf balls for it. Laminar flow may be nice to look at (which is why we use it in decorative fountains) but turbulent flow does the real lifting.

The focus of the lecture is on fluid dynamics and statics. Different properties are discussed, such as density and pressure. Archimedes' Principle is introduced and demonstrated through a number of problems. The final topic of the lecture is Bernoulli's Equation.
00:00 - Chapter 1. Introduction to Fluid Dynamics and Statics — The Notion of Pressure
04:14 - Chapter 2. Fluid Pressure as a Function of Height
20:49 - Chapter 3. The Hydraulic Press
26:32 - Chapter 4. Archimedes' Principle
36:36 - Chapter 5. Bernoulli's Equation
39:12 - Chapter 6. The Equation of Continuity
53:41 - Chapter 7. Applications of Bernoulli's Equation

With slow commercial #CFD software, compute time for my PhD studies would have exceeded decades. The only way to success was to master #GPU programming, write my own CFD solver from the ground up and turn runtime to days. Now a 10 billion cell simulation (like in the video) runs over night on an 8-GPU server, visualizing hundreds of TeraByte with my #OpenCL graphics engine.
I have since published my source code to make this powerful tool freely available to other researchers/students/hobbyists. Today #FluidX3D the most popular CFD code on GitHub with 1.6k Stargazers: https://github.com/ProjectPhysX/FluidX3D
Thanks to the people at Jülich Supercomputing Centre for letting me test their hardware!

Special thanks to these supporters: http://3b1b.co/divcurl-thanks
My work on this topic at Khan Academy: https://www.khanacademy.org/math/multivariable-calculus/multivariable-derivatives
Timestamps
0:00 - Vector fields
2:15 - What is divergence
4:31 - What is curl
5:47 - Maxwell's equations
7:36 - Dynamic systems
10:37 - Explaining the notation
13:28 - No more sponsor messages
Correction at 4:55, the narration should say "counterclockwise rotation gives positive curl, clockwise rotation gives negative curl". The diagram is correct, though.
For more fun fluid-flow illustrations, which heavily influenced how I animated this video, I think you'll really enjoy this site:
