What's a Gentle Introduction to Fluid Dynamics?

AI Thread Summary
A gentle introduction to fluid dynamics emphasizes starting with Bernoulli's principle, which applies to inviscid flow. As viscosity becomes a factor, the complexity increases, necessitating the use of Navier-Stokes equations. Boundary layer analysis is suggested as a more advanced topic, but it may overwhelm beginners. Plane Couette flow is recommended as a simpler example to ease into the subject. Understanding these foundational concepts is crucial before tackling more complex fluid dynamics topics.

They are removed by moving to more complicated equations such as Navier-Stokes.

Hehe, I liked your response.
To the OP, what boneh3ad is saying is that the main constraint for bernoulli is the flow is inviscid. To account for viscosity things get more complicated such as using N/S equations to deal with what occurs in viscous flows. For an application of this, look for topics related to boundary layer analysis to get a sample.

You are going to scare the kid by direction him straight to boundary layers. Baby steps. Plane Couette flow may be a nice starting point.

Baaah, what's so scary about boundary layers?
*cough* *cough* Good point however!

Hi,
I have a vessel I 3D printed to investigate single bubble rise. The vessel has a 4 mm gap separated by acrylic panels. This is essentially my viewing chamber where I can record the bubble motion. The vessel is open to atmosphere.
The bubble generation mechanism is composed of a syringe pump and glass capillary tube (Internal Diameter of 0.45 mm). I connect a 1/4” air line hose from the syringe to the capillary
The bubble is formed at the tip...
Scenario 1 (figure 1)
A continuous loop of elastic material is stretched around two metal bars. The top bar is attached to a load cell that reads force. The lower bar can be moved downwards to stretch the elastic material.
The lower bar is moved downwards until the two bars are 1190mm apart, stretching the elastic material. The bars are 5mm thick, so the total internal loop length is 1200mm (1190mm + 5mm + 5mm).
At this level of stretch, the load cell reads 45N tensile force.
Key numbers...
I'd like to create a thread with links to 3-D Printer resources, including printers and software package suggestions. My motivations are selfish, as I have a 3-D printed project that I'm working on, and I'd like to buy a simple printer and use low cost software to make the first prototype.
There are some previous threads about 3-D printing like this: https://www.physicsforums.com/threads/are-3d-printers-easy-to-use-yet.917489/
but none that address the overall topic (unless I've missed...
