On a methodology to determine whether the fluid slips adjacent to a solid surface

TL;DR

This paper proposes a practical methodology using measurable experimental data to determine whether the classical no-slip boundary condition applies to fluid flow near solid surfaces.

Contribution

It introduces a new approach to experimentally verify the validity of the no-slip boundary condition in fluid dynamics.

Findings

Method enables easy experimental verification of slip conditions.

Provides criteria to distinguish slip from no-slip regimes.

Applicable to various fluid-solid interface studies.

Abstract

We discuss a methodology that could be gainfully exploited using easily measurable experimental quantities to ascertain if the ``no-slip" boundary condition is appropriate for the flows of fluids past a solid boundary.
