1 On Thermal Instabilities in a Viscoelastic Fluid Subject to Internal Heat Generation

Authors: Donna M. G. Comissiong, Tyrone D. Dass, Harold Ramkissoon, Alana R. Sankar

Abstract:

The B'enard-Marangoni thermal instability problem for a viscoelastic Jeffreys- fluid layer with internal heat generation is investigated. The fluid layer is bounded above by a realistic free deformable surface and by a plane surface below. Our analysis shows that while the internal heat generation and the relaxation time both destabilize the fluid layer, its stability may be enhanced by an increased retardation time.

Keywords: relaxation time, internal heat generation, Maxwell model, viscoelastic fluid, Jeffreys' model, retardation time
