Wall slip effects on the fiber orientation of a short-fiber suspension in hyperbolic channel flow
Kostas D. Housiadas, Antony N. Beris, Suresh G. Advani
We investigate the effect of wall fluid slip on the orientation of non-Brownian, short, rigid, and high aspect ratio cylindrical fibers suspended in a Newtonian fluid in flow throu…

Fundamental evaluation of the pressure gradient for lubrication flows in varying channels: Application to inertial Newtonian flow in a linear channel
Panagiotis Sialmas, Kostas Housiadas
We derive general analytical expressions for the pressure gradient of a viscoelastic Oldroyd-B fluid in a symmetric channel with slowly varying geometry. Using classic lubrication…

An exact solution of the lubrication equations for the Oldroyd-B model in a hyperbolic channel
Kostas D. Housiadas
An exact similarity solution of the lubrication equations for the steady flow of a viscoelastic Oldroyd-B fluid in a contracting and symmetric hyperbolic channel is derived. The so…
