Simulation of a Non-Newtonian drop impact on a rigid surface: A mess-free approach
Abstract
The present study explores the impact of a non-Newtonian fluid drop on a rigid surface using a mesh-free approach, Smoothed Particle Hydrodynam-ics. The complex interaction between viscous and elastic forces during drop impact may be reproduced by integrating the Oldroyd-B model, which de-scribes viscoelastic fluids, into the developed computational framework. A suit-able boundary condition is assumed for interaction between fluid and solid sur-faces. The ongoing study examines how a droplet deforms, spreads, and recoils after an impact due to its viscoelasticity. The developed computational frame-work is validated by comparing results from existing literature, providing an understanding of how viscoelasticity influences drop-impact behaviour and opening up new avenues for subsequent research in fluid dynamic problems.
