Impact of electroosmotic flow on a Casson fluid driven by chemical reaction and convective boundary conditions

Abstract

AbstractA numerical and theoretical review of the electroosmosis flow effect on a transient state Casson fluid by natural convection stream past an exponentially accelerated plate is provided in this report. Additionally, porous medium, thermal radiation, magnetic field, electric field, ramped wall temperature and isothermal concentration are taken into consideration. The equation of Poisson–Boltzmann is used to depict the electrical potential profile within the fluid medium linearized by the Debye–Hückel implementation. Using the Laplace transform technique, the analytical solutions of momentum, energy, and concentration equations are determined. The obtained solutions of axial velocity, fluid temperature, and concentration expressions are diagrammatically revealed, and numerical results for the number of Nusselt are also obtained for critical related flow parameters. The natural convection of ramped wall temperature was also compared to the isothermal system. With the increase in Joule heating parameter, mass Grashof number, Prandtl number, and chemical reaction parameter, the velocity has been reduced for both the case of ramped and isothermal wall temperatures (RIWT). The uses of the RIWT are applicable to clean nuclear plant wastewater, food manufacturing, drilling operations, and bioengineering operations.
