Their unique properties make them suitable for diverse applications, ranging from heat exchangers to advanced industrial and medical treatments. Due to the practical applications and innovative features of THNFs, this paper aims to analyze the performance of these fluids to improve the efficiency of modern devices. The THNF is formulated by adding nanoparticles of three different kinds of aluminum oxide (Al<sub>2</sub>O<sub>3</sub>), silicon dioxide (SiO<sub>2</sub>), and copper (Cu) into water (H<sub>2</sub>O) based ethylene glycol (C<sub>2</sub>H<sub>6</sub>O<sub>2</sub>). The momentum equation is formulated considering the influences of Darcy Forchheimer, permeability, and magnetic field. Thermal radiation, intermolecular friction force, and Joule heating effects are accounted in the thermal field equation. Mass concentration relation is acquired considering binary chemical reaction and activation energy (AE). Additionally, the influence of stratifications (thermal and solutal) at the boundary of the cylinder is considered. The physical phenomenon representing partial differential equations is reduced into ordinary ones utilizing the transformations and then solved via Runge–Kutta Fehlberg (RKF-45) numerical scheme in Mathematics. Influence of involved sundry variables on HNF and THNF velocity, thermal field, mass concentration, surface drag force (skin friction coefficient), mass, and heat transfer rates were examined. The results showed that the velocity fields of THNF and HNF decay through variables Darcy Forchheimer, porosity, and Hartman number. Thermal field of THNF and HNF improves via radiation parameter, Eckert number, and Hartman number.

This research utilizes the reheat GT cycle (RGTC) as the top cycle and constructs four RGTC-supercritical/transcritical carbon dioxide (s/tCO<sub>2</sub>) combined cycle systems with progressively enhanced configurations of the CO<sub>2</sub> bottom cycle. Modeling and thermodynamic analysis are conducted using next-generation GT parameters. When the supercritical CO<sub>2</sub> (sCO<sub>2</sub>) dual recuperated bottom cycle (sCO<sub>2</sub>DRBC) is used as the bottom cycle, the high temperature at the CO<sub>2</sub> compressor outlet results in gas exhaust temperatures exceeding 100°C, indicating insufficient waste heat utilization. Consequently, the operating condition of the CO<sub>2</sub> bottom cycle is changed from supercritical to transcritical, utilizing the low-temperature CO<sub>2</sub> fluid at the pump outlet to further absorb waste heat from the gas. This modification results in a final gas exhaust temperature of ~70°C and a 2.84% increase in combined cycle energy efficiency. Additionally, considering the substantial latent heat of vaporization in the water within the gas, its effective utilization can further enhance cycle energy efficiency. Therefore, the transcritical CO<sub>2</sub> (tCO<sub>2</sub>)DRBC is further refined by incorporating a medium-temperature turbine (MT), medium-temperature recuperator (MTR), and phase change heater (PH) to form the modified tCO<sub>2</sub> bottom cycle I (tCO<sub>2</sub>MBC-I). The RGTC-tCO<sub>2</sub>MBC-I combined cycle achieves a 69.56% combined cycle energy efficiency with the absorption of some gas latent heat, demonstrating a significant improvement in energy efficiency. Further analysis reveals that the flow rate of the bottom CO<sub>2</sub> cycle is increased by the enhanced design due to the need to absorb additional gas latent heat, exacerbating losses at the bottom cycle precooler. Consequently, an expander (positioned before the precooler) is integrated into the tCO<sub>2</sub>MBC-I to form the modified tCO<sub>2</sub> bottom cycle II (tCO<sub>2</sub>MBC-II). Calculated results indicate an energy efficiency of 69.91% for the RGTC-tCO<sub>2</sub>MBC-II combined cycle. This paper presents three modifications to the previously studied sCO<sub>2</sub>DRBC, with the final RGTC-tCO<sub>2</sub>MBC-II combined cycle demonstrating considerable energy efficiency advantages.

Experiments were conducted across seven preset orientation angles ranging from 0° to 180°. The experimental results indicated that these conditions had a notable effect on heat transfer performance, with the highest CHF observed at a 60° orientation for both types of surfaces.

The present research work investigates the performance, combustion, and emission behavior of rubber seed biodiesel (RSB)/diesel blends (B20, B30, B40) and B20 + ethyl hexyl nitrate (EHN) at four injection timings (19°, 21°, 25°, and 27° before top dead center [BTDC]) in a single-cylinder DI diesel engine.

The addition of EHN reduced hydrocarbon (HC) emissions but negatively impacted brake-specific fuel consumption (BSFC) and brake thermal efficiency (BTE). However, advanced injection timing not only restored the combustion parameters to the B20 level but also brought them closer to those of the diesel engine. Advancing the injection timing to 27° BTDC improved BSFC and BTE by 3% and 4% compared to B20, respectively. Additionally, the HC emission decreased strongly by 80% and 73%, and smoke emission decreased by 15% and 16%, respectively, compared to B20 and diesel fuel values. A slight improvement in NO<sub>x</sub> emissions (by 2%) was also observed compared to B20. An increase in cylinder pressure from 66.2 to 67.4 bar was observed with advanced injection timing, contributing to improved engine performance.
