Abstract
It was shown above that vortexes cannot originate or disappear in an ideal (inviscid) fluid moving in the field of a potential force. Consequently, if the flow is potential initially (i.e., curl υ = 0 everywhere), it remains so indefinitely. Of course, one can constantly observe the creation and disappearance of the vortexes in a real fluid. Nevertheless, it is reasonable to first consider some problems of a potential flow since this very often appears to be a good approximation to real fluid flow; in addition, the equations describing this flow are much simpler.
