### Flow Past a Spherical Obstacle: azimuthal symmetry

For a flow passing a spherical obstacle, I don't really understand why the azimuthal term $\frac{1}{r^2 sin^2 \theta} \frac{\partial^2 \phi}{\partial \varphi^2}$ of $\vec{v} = - \nabla \phi$ is 0. ...

### Low Reynolds number flow and Potential flow

In an experiment conducted in my lab, we observed a low Reynolds number flow between two parallel plates with narrow gap between them resemble Potential Flow which is quite counter-intuitive as low ...

### By what mechanism is lift produced on a rotating cylinder in an inviscid flow?

I am taking some introductory fluid dynamic classes, and have become very confused by the Kutta-Joukowski theorem. One of the conclusions that can be derived by applying Kutta-Joukowski is that a ...

### What is "full clutching flow" in fluid-dynamics with regards venturi design?

As the title says, what is "full clutching flow" in fluid-dynamics with regards venturi design? I came across this reference a few times and can not find any further info on it, I'm currently ...

### What is a Physically Accurate Explanation for the Kutta Condition?

Countless arguments between highly intelligent people have been waged (on this very site in fact) as to exactly how lift can be explained in an experimentally and mathematically rigorous way. Taking ...

### Why does (potential) fluid flow bend around a solid surface in the flow?

Potential flow obeys Laplace's equation with certain boundary conditions (i.e. no fluid penetrates the solid body in flow, and far away from the body, the flow is uniform with a given velocity and ...
