This work describes an inviscid solution for a cyclonic flowfield evolving in a hemispherical chamber configuration. In this context, a vigorously swirling motion is triggered by a gaseous …
This study focuses on the development of an internal potential flow solution in the context of a hemispherically bounded cyclonic chamber. The analysis proceeds from the Bragg …
SWIRLING motions have attracted much attention in recent years due to the rich structures that they engender. At one end of the spectrum, one is concerned with understanding …
