We investigate theoretically the steady incompressible viscoelastic flow in a hyperbolic
contracting channel. The fluid viscoelasticity is modeled using the upper convected Maxwell …

Lubricating oils are used to minimize the friction and wear of mechanical components by
virtue of a thin lubricant film separating the sliding surfaces. The film's characteristics, under …

We analyse the pressure-driven flow of the Oldroyd-B fluid in slowly varying arbitrarily
shaped, narrow channels and present a theoretical framework for calculating the …

We investigate theoretically the steady incompressible viscoelastic flow in a rigid
axisymmetric cylindrical pipe with varying cross-section. We use the Oldroyd-B viscoelastic …

In this work we study the influence of fluid viscoelasticity on the performance of lubricated
contacts in the presence of cavitation. Several studies of viscoelastic lubricants have been …

We analyze the steady non-Newtonian fluid–structure interaction between the flow of an
Oldroyd-B fluid and a deformable channel. Specifically, we provide a theoretical framework …

We study the mechanically driven flows of non-Newtonian fluids in narrow and confined
configurations. Using the Lorentz reciprocal theorem, we derive a closed-form expression for …

Lubrication is essential to minimize wear and friction between contacting surfaces in relative
motion. Oil based lubricants are often enhanced via polymer additives to minimize self …

We present new theoretical developments on the incompressible viscoelastic flow of an
Oldroyd-B fluid in a hyperbolic contracting symmetric channel. We show uniformity of the …

In the quest for sustainable lubrication, this study explores the potential of water-based
lubricants (WBLs) with amino acid ionic liquid (AAIL) additives. The research combines …
