Abstract

The present analysis investigates an unsteady conducting water-based nanofluid embedding with porous medium over an exponentially accelerated vertical plate. The plate is accelerated with moving ramped temperature. However, water is treated as the base fluid with Copper (Cu) and Titanium Oxide (TiO₂) as nanoparticles. Effects of thermal radiation, heat source, and radiation absorption are taken care of in the energy equation which may enhance the heat transfer properties of nanofluid. The crux of the investigation is to find the closed-form solution of nonlinear coupled partial differential equations. Laplace Transform technique is employed to solve these equations. The influence of the contributing parameters for the flow phenomena, in particular, thermal buoyancy parameter, thermal radiation, heat source/sink, and Prandtl number along with others are obtained and presented via graphs. Rate of shear stress and heat transfer coefficients for the significance of physical quantities of interest are also obtained and presented through graphs. Results and discussion section is devoted which elaborates on the behaviors of these, the emerging parameters. However, augmentation in the thermal profile is observed due to the heat sink as well as the thermal radiation parameters and nanoparticle volume fraction retards the velocity distribution due to the heavier density of the Cu nanoparticles.
