Taylor dispersion in variable-density, variable-viscosity pulsatile flows
Prabakaran Rajamanickam, Adam D. Weiss
The phenomenon of Taylor or shear-induced dispersion of a non-passive scalar field in a pulsatile pipe flow is investigated, accounting for the scalar field's influence on fluid de…
A note on viscous flow induced by half-line sources bounded by conical surfaces
Prabakaran Rajamanickam, Adam D. Weiss
In this paper axisymmetric solutions of the Navier-Stokes equations governing the flow induced by a half-line source when the fluid domain is bounded by a conical wall are discusse…
Steady axisymmetric vortices in radial stagnation flows
Prabakaran Rajamanickam, Adam D. Weiss
A class of axisymmetric vortex solutions superposed upon radial stagnation flows is described. The new vortex solutions generalize the classical Burgers' vortex and Sullivan's vort…
Effects of thermal expansion on Taylor dispersion-controlled diffusion flames
Prabakaran Rajamanickam, Adam D. Weiss
A theoretical analysis is developed to investigate the effects of gas expansion due to heat release on unsteady diffusion flames evolving in a pipe flow in which the mixing of reac…
A model for the constant-density boundary layer surrounding fire whirls
Adam D. Weiss, Prabakaran Rajamanickam, Wilfried Coenen +2
This paper investigates the steady axisymmetric structure of the cold boundary-layer flow surrounding fire whirls developing over localized fuel sources lying on a horizontal surfa…
