Mr. Curtis Boodoo's PhD. Seminar

Event Date(s): 26/11/2009

Location: Room FSA 313, 3rd floor Natural Science Building


Mr. Curtis Boodoo will present his PhD. seminar, titled "Steady creeping motion, under gravity, of a single large micropolar liquid bubble in an immiscible viscous Newtonian fluid bounded by a vertical porous tube," on Thursday 26th November, 2009, from 3 pm-4 pm. It will be held in Room FSA 313, 3rd floor Natural Science Building.

 

Abstract:

The steady creeping motion under gravity of a single large liquid bubble in a Newtonian fluid bounded by a vertical porous tube is studied. The fluid inside the bubble is modeled as a micropolar fluid and the bubble is covered in a thin film of Newtonian fluid.

Where the Newtonian film enters the porous region a Brinkmann model is used, the remainder of the porous tube is modeled as a Darcy region. At the interface of the Newtonian film and the porous region a stress jump boundary condition for tangential stresses is used.

Velocity and Pressure gradient plots for the different fluid and porous regions is presented and a comparison among the Brinkmann – Darcy model used in this paper and a Darcy model and Brinkmann model used in previous papers is also presented.
