I was wondering if it's possible to have a soap bubble with a varying pressure over its surface? That is, such a bubble would not have constant internal pressure at all points.
I am specifically interested in this for modelling a situation in which a soap bubble is placed in a stream of moving air, or a situation in which a soap bubble is heated, in both of which cases there may be significant variation in external pressure over the surface of the bubble.
If this is possible, does the Young-Laplace equation still hold in some form (eg. at each point on the surface of the bubble)?
Thanks for any responses.
