“…Raju and Reddy [8] who investigated the non-Newtonian Casson fluid on permeable stretching sheet discovered that the heat transfer flow was affected by irregular heat source and sink. Ragupathi et al, [9] studied the 3D flow of hybrid nanofluid on a Riga plate with irregular heat source/sink. The study found that the non-uniform heat source/sink increases the thermal boundary layer.…”

This research studies the behaviour of hybrid nanofluid on mixed convection flow over a stretching sheet by considering the effect of non-uniform heat source/sink. The chosen base fluid is water with two different nanoparticles which are copper and aluminium oxide. The governing partial differential equations are reduced into ordinary differential equations using a similarity transformation technique. The resulting governing system then solved numerically using Keller-box method. The influence of space- and temperature-dependents of non-uniform heat source and sink parameters as well as the unsteadiness parameter is presented graphically. The current study shows that, the space- and temperature dependents of non-uniform heat source and sink significantly raises the fluid’s temperature. Comparative study also shows that hybrid nanofluid has higher temperature and heat transfer coefficient than single nanofluid and conventional fluid. It can also be concluded that, the enhancement of heat transfer rate can be achieved by reducing the parameter of space- and temperature dependents of non-uniform heat source and sink.

“…Heat transfer characteristics along with Joule and viscous dissipation were analyzed by considering the effect of nonuniform heat source/sink and it was found that the inclination angle parameter increases the thickness of the thermal boundary layer.

Over the past few decades, several researchers have produced a variety of nanofluids that are used as heat transfer fluids in many engineering and technological processes. A nanofluid is a kind of heat transfer fluid, containing nanoparticles (1-100 nm) that are uniformly and stably distributed in a base fluid. Nanoparticles can be metallic/intermetallic compounds, such as Ag, Cu, Ni, Au, Fe, and ceramic compounds such as oxides, sulfides and carbides. Liquids such as water, ethylene glycol, a mixture of water and ethylene glycol, diethylene glycol, polyethylene glycol, engine oil, vegetable oil, paraffin, coconut oil, gear oil, kerosene, and pump oil are used as base fluids. A wide range of applications for nanofluids in different areas have been reported in the literature. These include biomedical applications, lubrication, surface coating, petroleum processing, environmental remediation, and cooling systems for electronics.

“…They obtained that the heat transfer gradient aggravates for a higher magnitude of the heat sink parameter, whereas it subsides when improving the heat source parameter. The impact of inconsistent heat source/sink of the 3D flow of F e 3 O 4 /Al 2 O 3 nanoparticles past a Riga plate was studied by Ragupathi et al [31]. They have seen that the heat source parameter develops the thermal boundary layer thickness.…”

This research communication explains the flow of water/kerosene-based CNTs (carbon nanotubes) over a Riga sheet. The energy analysis is debated with the availability of radiation, viscous dissipation, and convective heating conditions. Two divisions of CNTs, like, SWCNTs (single-wall carbon nanotubes) and MWCNTs (multiwall carbon nanotubes), are considered. The pertinent variables are applied to overhaul the governing mathematical models into ODE expressions. The overhaul expressions are analytically solved by HAM (homotopy analysis method) and numerically solved by MATLAB bvp4c scheme. The repercussions of relevant parameters on nanoliquid velocity, nanoliquid temperature, skin friction coefficient, and local Nusselt number are inspected via graphs, tables, and charts. Our computational results are compared with the previous researcher results and have the most acceptable agreement. Our outcomes are used to understand the flow attributes, behavior, and how to predict it for those working in the design of thermal equipment in thermal industry. It is noticed that the nanoliquid velocity decayed in counter to the unsteady parameter, and it enhances for larger values of Hartmann number. The nanoliquid temperature enriches when raising the Biot number and radiation parameter. The change in unsteady parameter decays the surface shear stress, while reverse results are found in the local Nusselt number.
