Numerical solution of radiation and viscous dissipation effects on flow past an oscillating plate with chemical reaction

Abstract

The objective of this research is to investigate the unsteady natural newlineconvection flow in an incompressible, viscous fluid as it moves over an newlineoscillating semi-infinite vertical plate by using finite-difference method. The newlinestudy considers the impact of thermal radiation, viscous dissipation, and newlinechemical reactions, along with the presence or absence of magnetic field newlineeffects. The plate possesses consistent surface temperature and mass diffusion newlineproperties. Initially, both the plate and the adjacent fluid exist at ambient newlinetemperature and concentration levels. However, once the plate starts oscillating newlinevertically with a uniform velocity against the force of gravity, the temperature newlineand concentration in the vicinity of the plate are perturbed, leading to natural newlineconvection induced by the temperature and concentration gradients. newlineChapter 1 is a general introduction, and it explains the proper newlineunderstanding of the concepts of boundary layer theory, heat transfer, modes newlineof heat transfer, natural convection flow, mass transfer, types of mass transfer, newlineheat and mass transfer effects, MHD (Magneto Hydro Dynamics) effects, newlineradiation effects, viscous dissipation effects, chemical reaction effects, the newlinegoverning equation of the flow, dimensionless parameters, and the finite newlinedifference method. newlineChapter 2 emphasizes the utilization of numerical methods for newlinesolving the problem of unsteady natural convection flow of a viscous, newlineincompressible fluid along an oscillating semi-boundless vertical plate with newlineuniform mass diffusion and temperature. The study also considered the factors newlinesuch as thermal radiation and viscous dissipation. In this context, the fluid is newlinecharacterized as optically thin, gray, and exhibiting absorbing-emitting newlineradiation, but it is considered to be a non-dispersing medium. newline
