In this paper, we delve into the behavior of binary micropolar nanofluids, specifically micropolar‐Jeffrey, micropolar‐Oldroyd‐B, and micropolar‐Second grade, within the parabolic trough solar collector (PTSC) configurations. The primary objective is to enhance the collective efficiency of this device by means of a comprehensive comparison amongst the three aforementioned nanofluids. The governing equations, including continuity, linear momentum, angular momentum, and energy equations, were systematically formulated. Subsequently, the introduction of suitable similarity variables facilitated the transformation of the intricate partial differential equations into manageable ordinary differential equations. These resultant equations were then tackled utilizing the shooting method via the bvp4c numerical package in MATLAB. The study critically examines the influence of diverse parameters that dictate the flow dynamics of the nanofluids. This encompasses nanofluid velocity, angular velocity, temperature distribution, entropy generation, skin friction coefficient, and local Nusselt number. Remarkably, the research uncovers that the maximum temperature levels experienced enhancements of 12.1134%, 12.0616%, and 11.0645% for the micropolar‐Jeffrey, micropolar‐Oldroyd‐B, and micropolar‐Second grade nanofluids, respectively. These results imply that the introduction of these binary micropolar nanofluids leads to notable thermal enhancements in the PTSCs settings.

A novel notion in the realm of research is that ternary nanofluid presents itself as a cutting-edge concept showcasing enhanced heat transfer capabilities when pitted against hybrid nanofluids as well as traditional nanofluids. These ternary nanofluids are employed for boosting thermal conductivity in cooling systems, thereby enhancing energy efficiency in electronics and industrial operations. This research aims to investigate the dynamic viscosity variations within a three-component nanofluid comprising Ag, Gr, and GO nanoparticles suspended in water enclosed between dual parallel plates with entropy generation. The examination encompasses the impact of viscous dissipation, thermophoresis, and Brownian motion occurrences within the energy equation, alongside considering chemical reactions in the concentration equation. Techniques of similarity are utilized to transform the complex nonlinear partial differential equations into a collection of ordinary differential equations. The necessary equations that arise are attempted through the utilization of the Runge-Kutta-Fehlberg technique in combination with a shooting method. The research examines graphs and tables to study the effects of new factors on velocity, temperature, concentration, and engineering measures. The outcome of the finding shows that the magnetic field and suction cause a greater decrease in [Ag/H2O]n nanofluid velocity while increased squeezing limit elevate [Ag+Gr+GO/H2O]t ternary nanofluid velocity. Increasing thermophoresis and Brownian motion enhances temperature in ternary nanofluid but [Ag/H2O]n nanofluid concentration diminishes with chemical reaction. Entropy production intensifies in ternary nanofluids due to higher radiation and Brinkman number. The magnetic field increases skin friction of ternary nanofluids by 3.4% at both plates but it decreases by 4.12 more in nanofluids because of alterations in viscosity factor. Heat transfer decreases by 3.05% at the lower plate but increases by 6.01% at the upper plate in ternary nanofluids due to heat production, and thermophoresis. An increase of 3.95% in mass transfer rate is observed in the ternary nanofluid at the lower plate but a decrease of 2.06% is noted at the upper plate due to thermophoresis and Brownian motion. The discoveries illuminate the possibilities of ternary nanofluids to boost thermal conductivity and maximize energy efficiency across a range of industrial applications.
