This research aims to examine the tri-hybrid nanofluid flow in a convectively heated permeable channel with the effect of heat generation/absorption. Tri-hybrid nanofluid is formed by suspending three different nanoparticles namely, aluminium oxide (Al2O3), copper (Cu) and nickel (Ni) in the base fluid water (H2O). For stability of the fluid transverse magnetic and electric fields are considered in the fluid model. The aim of this work is to carry out a comparative study for the heat transfer enhancement of base fluid with mono (Al2O3), hybrid (Al2O3+Cu) and ternary (Al2O3+Cu+Ni) nanofluids. This study is implicated in those fields which are dealing with extreme heat or cold conditions, aerospace technology, biosensors, nano-drugs and metal coatings. The boundary layer equations that govern the flow are transformed to dimension-free form by appropriate transformable variables and then solved by using bvp4c program in MATLAB software. It is found that the fluid flow resist by magnetic parameter and assist by electric field, while the thermal profiles rise by enhancing the value of these parameters. Furthermore, numerical outcomes for skinfriction coefficient and Nusselt number are deliberated in graphical form. Thus, it is concluded that, ternary hybrid nanofluid enhances the thermal conductivity of the base fluid more than to traditional or hybrid nanofluid.

This work aims to study the different characteristics of Newtonian fluid flow and heat transfer througha 1:3 sudden expansion channel with or without plane baffles using the finite volume method. The flowis assumed viscous, incompressible, steady, and laminar. The different characteristics of hydro-thermalfluid flow phenomena have been studied for 𝑅𝑒 ∈ [0.1 − 200] to demonstrate the influence of thepresence of baffles. The profiles of velocity, pressure, skin friction coefficient, friction factor, averageNusselt number, and pumping power have been examined for both the cases of the presence and absenceof baffles. It has been observed that the hydro-thermal characteristics become more pronounced withthe increase in the number of baffles. In the case of three baffles of equal length, at 𝑅𝑒 = 200 it iscalculated that if the thickness of the baffles is same and equal to 10% of the length, then the value of Nu becomes approximately 1.2 times of that in the absence of baffle. For the same value of Re, ithas been found that for the presence of one baffle of length equal to the width of the inlet section of thechannel and of thickness 10% of the same, the value of 𝑁𝑢􀯔􀯩 becomes 1.11 times of that in the absenceof baffle, while in the case of three baffles of equal length and of equal thickness like the abovementioned case of one baffle, the value of 𝑁𝑢􀯔􀯩 becomes 1.25 times of that in absence of baffle. It hasalso been revealed that the enhancement of thermal phenomena increases with the increase inthe baffle’s height.
