Thermophoretic particle deposition in Carreau-Yasuda fluid over chemical reactive Riga plate

Abstract

Marangoni convection is very useful in coating flow technology, surfactant replacement therapy for neonatal children, microfluidics, drying of semi-conductor vapors in microelectronics, foams, and film drainage in emulsions. The behavior of gyrotactic microorganisms and chemical reaction on the Marangoni convected Carreau-Yasuda liquid flowing over Riga plate with thermophoretic particle deposition is reported in this research. The Riga plate is self-possessed of magnets and electrodes. The fluid conducted electricity and the vertical Lorentz force has been exponentially increased. Thermal and mass species phenomena are investigated within the context of Dufour and Soret impacts. The PDEs are transformed into ODEs by the implication of suitable transformations. The resulting system of equations is solved by using homotopy analysis method (HAM). Using tables and graphs, the effects of dimensionless parameters on flow fields are described. The wall drag coefficient and pertinent flow rates are organized and stated. The results revealed that the temperature, concentration, and microorganisms profiles decay but the velocity profile augmented as the Marangoni ratio parameter increases.

Numerically analysis of Marangoni convective flow of hybrid nanofluid over an infinite disk with thermophoresis particle deposition

“…Due to their extensive usage in the disciplines of space processing, microgravity science and industrial manufacturing procedures, governing equations have drawn the attention of the majority of researchers who are interested in modeling these external forces. The importance of thermo-solutal Marangoni convection flows in the procedure of mass and heat transfer into various schemes has been carefully examined in 1 – 5 Chemical reaction in the thermo-solutal Marangoni convective flow across the Riga plate was studied by Shafiq et al 6 . The encouragements of heat radiation on Marangoni convective flow were examined by Hayat et al 7 Microorganisms that are typically 5–10% denser than water swim upward in fluid flow known as bio-convection.…”

Numerical study for bioconvection in Marangoni convective flow of Cross nanofluid with convective boundary conditions

“…Numerous manufacturing and micro-engineering applications, such as safeguarding nuclear reactors, contamination, cleaning gas, avoiding micro- and avoiding heat exchanger corrosion, all benefit from the thermophoresis phenomena. In a Carreau-Yasuda fluid over a chemically reactive Riga plate, Abbas et al 27 investigation concentrated on the thermophoretic particle deposition. A thin moving needle was the subject of an investigation by Kumar et al 28 into the effects of thermophoresis on mass and heat transport of Casson fluid flow.…”

Numerical analysis of Marangoni convected dusty second-grade nanofluid flow in a suspension of chemically reactive microorganisms

“…The study of mass and heat convection in this phenomena sparked widespread interest because of its numerous applications in daily life such as thin liquid layer scattering, crystal growth, atomic reactor, dynamic use in the varnish, freezing agents, non-lubricating agents, welding process, material science, the processing of semiconductor, and silicon melt. As a result, many researchers [21][22][23][24][25][26][27][28][29][30] contributed to this topic after Marangoni.…”
