In this paper, we discuss the merits of two models for the swirl velocity in the core of a
confined bidirectional vortex. The first is piecewise, Rankine-like, based on a combined …

A two-cell vortex solution to the Navier–Stokes equations is derived in this article. The
theoretical analysis provides expressions for the velocity components, vorticity, and pressure …

Expanding our previous work on turbulent whirls [1] we have uncovered a similarity within
the similarity shared by intense vortices. Using the new information we compress the …

A theoretical investigation from the view point of gas-dynamics and thermodynamics was
carried out, in order to clarify the energy separation mechanism in an unconfined laminar …

A new analytical solution for self-similar compressible vortices is derived in this paper.
Based on the previous incompressible formulation of intense vortices, we derived a …

Two celled incompressible vortices are known from the work of Sullivan (1959). This
dissertation first extends the previously derived wider latitude, incompressible, steady two …

In this dissertation, a number of models are derived to describe swirling flows. Both
generalized compressible Bragg-Hawthorne and vorticity-stream function frameworks are …
