MODELLING AND SIMULATION OF HEAT AND MASS TRANSFER IN 3-D WATER FLOW OVER A STRETCHING SURFACE

Abstract

The fluid-flow model is evaluating by investigative the mass and energy transfer of the hybrid nanofluid over a stretching permeable sheet. The performance of the nanofluid can be enhanced, optimized, and stabilized by incorporating nanoparticles with distinct thermal and rheological characteristics. This study examines the flow dynamics, heat transfer, and mass transport characteristics of a hybrid nanofluid. It also takes into consider the effects of thermal radiation, chemical processes, slip effects, and MHD. The hybrid nanofluid is made by mixing water with copper and alumina nanoparticles. To reduce the complexity of the governing PDE that describe the flow and heat and mass transfer, the self-similar approach is employed. The system of ODE, after reduction, is typically non-linear and requires numerical methods for solution. The bvp4c solver is a boundary value problem solver in MATLAB, specifically designed for solving boundary value problems for ODE. The influence of different non-dimensional physical flow parameters on changed flow profiles, such as velocity, temperature, and concentration, is illustrate through graphs. The velocity profiles reduce suitable to the special effects of magnetic and slip parameters. Additionally, the slip parameters for temperature and concentration direct to a decrease in their particular profiles. An increase in the thermal slip parameter result in a thinner boundary-layer and make possible the transfer of heat from the surface to the fluid. although, the mass transfer velocity decreases as the solute slip parameter increases. An evaluation with active studies in the literature shows exceptional accord between the results.
