Abstract Automotive radiators are primarily utilized in vehicles to dissipate the heat generated by engine block into surrounding. Utilizing coolants with superior thermophysical properties reduces power consumption and improves cooling performance. Comprehending correlation between coolant characteristics its thermohydraulic behavior is essential for advancing this innovative technology. This investigation introduces a detailed parametric study of an automotive radiator using diversified mixtures. Ethylene glycol (EG)/water mixtures, namely, (40:60), (50:50), (60:40) as coolant. The influences operational mechanism parameters, that is, inlet temperature, intake air airflow rate, flowrate, mixture ratio on effectiveness, transfer, fluid flow investigated. A coupled model, based effectiveness‐NTU thermal resistance theories, developed simulation investigated radiator. outcomes revealed transfer rate more significantly influenced temperatures than flowrate. Findings reveal optimal conditions design be (40 EG:60 Water), Reynolds number 1087.5, 2175, 11°C air‐intake 94.25°C temperature maximization. findings also indicated optimum yielded maximum advantage (AR) lowest pumping power, which achieved 7.94% 19.30% higher AR compared (50:50) solutions, respectively. From energy reduction prospective, EG/water results 25.11% 49.77%, respectively, under same operating conditions. Conclusively, optimized explored offers promising approach improving vehicle technology increasing efficiency internal combustion engines.

This work presents a numerical investigation of laminar flow [Formula: see text] tetra-hybrid nanoliquid in microtube subjected to constant wall heat flux. A model was developed and validated using available experimental analytical data. The combined effects volume fraction, viscous dissipation, slip velocity, external magnetic field on transfer irreversibility parameters are investigated. results revealed that enhances the microflow comparison with base liquid, mono, di, ternary hybrid nanoliquids, an increase all components reduction Bejan number. higher velocity improves reduces total entropy production, while Brinkman number increases production. nanoparticle or intensity field, leads evolutions discussed this paper.
