Dispersion of passive & reactive solute in channel flows of a Kuvshiniski Viscoelastic fluid

Abstract

This abstract presents a brief survey with simulation & experimentations on the advanced research topic of “Dispersion of passive & reactive solute in channel flows of a Kuvshiniski Viscoelastic fluid”. The dispersion of solutes in fluid flows is a topic of significant importance in various scientific and engineering applications. Understanding the behavior of solute dispersion is crucial for optimizing transport processes, such as in chemical reactions, pollutant transport, and drug delivery systems. In this research, we investigate the dispersion characteristics of passive and reactive solutes in channel flows of Krushinski viscoelastic fluids. Krushinski fluids are a class of viscoelastic fluids that exhibit both viscous and elastic properties. They are commonly encountered in many industrial processes, such as polymer processing, coating flows, and biological systems. The viscoelastic nature of these fluids introduces complex flow behaviors, including flow instabilities, elasticity-induced turbulence, and non-Newtonian effects. The presence of solutes in such flows further complicates the system dynamics and requires a comprehensive understanding to optimize process performance.

In this study, we focus on the dispersion of passive and reactive solutes in channel flows of Krushinski viscoelastic fluids. Passive solutes are non-reactive and undergo dispersion primarily due to convective mixing and diffusion. Reactive solutes, on the other hand, participate in chemical reactions within the fluid flow, which adds an additional layer of complexity to their dispersion behavior. To investigate the dispersion characteristics, we employ both experimental and computational methods. In the experimental setup, we utilize a specially designed channel flow apparatus to measure solute concentration profiles along the flow direction. Various concentrations of passive and reactive solutes are introduced into the flow, and their dispersion is monitored using optical techniques such as laser-induced fluorescence. The experimental data provide valuable insights into the dispersion patterns and the effect of flow conditions, solute properties, and reaction kinetics
