Thermal analysis of double diffusive electrokinetic thermally radiated TiO₂-Ag/blood stream triggered by synthetic cilia under buoyancy forces and activation energy

Abstract

Second law analysis of double diffusive cilia endorsed transport of thermally radiated hybrid nanofluid through an electroosmotic pump is deliberated in this study. Joint effects of applied Lorentz force, activation energy and Joule heating on the proposed stream are also examined. Channel inner surface is shielded with artificial cilia carpet that ensures flow induction and micro-mixing activity in the fluid. After applying the lubrication and the Debye-Huckel estimations, numerical solutions of the envisioned problem are calculated. The analysis reveals that the elevated electric potential and prolonged cilia assist directional flow spreads over large distances. The augmentation in fluid stream is seen near the channel surface for higher electroosmotic parameter. Presence of activation energy input and thin electric double layer supports mass dispersion and control heat indulges. The present model provides an immediate understanding about the promising role of fabricated cilia in electroosmotic pumps for the future biomimetic micro and nanofluidic devices.

Microfluidic Applications of Artificial Cilia: Recent Progress, Demonstration, and Future Perspectives

“…The presence of the artificial cilia in the electroosmotic pumps needs to be noticed very well for future bioinspired thermal micro/nanofluidic technologies. Recently, Saleem et al [ 128 ] numerically analyzed the transportation of thermally radiated nanofluid in the microchannel in which the inside layer was settled with artificial cilia. In similar physical conditions, parameters such as electric potential, directional flow, velocity, pressure, temperature, and entropy generation were numerically analyzed by the same group [ 129 , 130 , 131 ].…”

“…The cartesian coordinate system is framed by taking the axis X along the wave transmission and the Y-axis in the upright direction. The cilia geometry is expressed by the following wave function [33,34]:…”

Thermal Case Study of Cilia Actuated Transport of Radiated Blood-Based Ternary Nanofluid under the Action of Tilted Magnetic Field

“…Based on this approach, different fabrication methods have been demonstrated to introduce artificial cilia capable of microfluidic pumping. In this regard, Saleem et al [16] reported that the artificial cilia inserted inside the channel surface facilitate micro-mixing and manipulate fluid flow. An MHD biomimetic blood pump model was suggested by Ramesh et al [17].…”

“…Some interesting studies of fabricated cilia in the perception of microfluidic processing, instantaneous mixing and pumping are mentioned [16][17][18][19]. In this regime, Javid et al [20] presented a mathematical model of pumping transport induced by cilia stimulated asymmetric metachronal waves and reported that prolonged cilia contribute to fluid flow enhancement.…”
