Hard to find bubble rise paper/bubble shape determination

AI Thread Summary
A user is seeking a specific paper by O. M. Kiselev on gas-bubble shape in axisymmetric flow, but faces challenges since the journal didn't start publishing until 1965. They are also looking for literature on bubble shape evolution as a variational problem, noting that many existing papers make assumptions rather than deriving shapes from first principles. References to works by Frolov and Landau and Lifgarbagez are mentioned, but the user has difficulty locating specific pages. They have derived an equation that behaves correctly under certain conditions but struggle with perturbative solutions involving density gradients. The user expresses a desire for seminal papers that minimize free energy and provide approximate solutions for bubble shapes.

Hi all. I'm looking for a paper that I've seen referenced in a couple of articles I've been reading. The paper is

O. M. Kiselev, Determination of gas-bubble shape in axisymmetric flow of fluid, Zh. Prikl. Mekhan. Tekh. Fiz., No. 3 (1963).

The English name of the journal is Journal of Applied Mechanics and Technical Physics. The biggest obstacle to me getting this paper is the fact that the journal didn't begin publication until 1965!

More generally, does anyone know of any papers treating bubble shape evolution as a variational problem? All of the papers I've found make assumptions about bubble shape and then worry about the fluid dynamics.

I read one paper by Frolov that suggests that Landau and Lifgarbagez tackle this problem in their Fluid Mechanics book, but I can't seem to find the page for this.

Thanks.

Thanks for the references. I guess what I'm really looking for is a seminal paper in this field in which the free energy is minimized and an equation for the bubble is found, and solved approximately. I've already produced what I think is the correct equation. It has the correct behavior in the absence of a density gradient (i.e. assuming constant radius leads to Young-Laplace), but the perturbative solution for a small density gradient is not forthcoming.

It seems like this is the kind of calculation that someone would have done 50-100 years ago, but I just can't find it. I was hopeful that the 1963 paper I mentioned would be what I'm looking for, but as I say it's nowhere to be found.
 
Thanks. I've come across several interesting articles published in the Cambridge Journal of Fluid Dynamics, including these two. Unfortunately my school only has a subscription for 1997-present, so I haven't been able to view them. I'm currently figuring out how I can access them.
 
Thread ''splain this hydrostatic paradox in tiny words'
This is (ostensibly) not a trick shot or video*. The scale was balanced before any blue water was added. 550mL of blue water was added to the left side. only 60mL of water needed to be added to the right side to re-balance the scale. Apparently, the scale will balance when the height of the two columns is equal. The left side of the scale only feels the weight of the column above the lower "tail" of the funnel (i.e. 60mL). So where does the weight of the remaining (550-60=) 490mL go...
Consider an extremely long and perfectly calibrated scale. A car with a mass of 1000 kg is placed on it, and the scale registers this weight accurately. Now, suppose the car begins to move, reaching very high speeds. Neglecting air resistance and rolling friction, if the car attains, for example, a velocity of 500 km/h, will the scale still indicate a weight corresponding to 1000 kg, or will the measured value decrease as a result of the motion? In a second scenario, imagine a person with a...
Scalar and vector potentials in Coulomb gauge Assume Coulomb gauge so that $$\nabla \cdot \mathbf{A}=0.\tag{1}$$ The scalar potential ##\phi## is described by Poisson's equation $$\nabla^2 \phi = -\frac{\rho}{\varepsilon_0}\tag{2}$$ which has the instantaneous general solution given by $$\phi(\mathbf{r},t)=\frac{1}{4\pi\varepsilon_0}\int \frac{\rho(\mathbf{r}',t)}{|\mathbf{r}-\mathbf{r}'|}d^3r'.\tag{3}$$ In Coulomb gauge the vector potential ##\mathbf{A}## is given by...
