The utilization of nanofluids has found numerous applications in various industries, including transportation, electronics, and energy. By substituting conventional fluids with nanofluids, heat transfer rates can increase. This not only enhances engine efficiency, leading to decreased fuel consumption but also enables the design of more powerful engines adaptable to various climates. This study focuses on a hybrid nanofluid composed of graphene oxide and silicon oxide nanoparticles in a water-ethylene glycol base fluid, which can have an application in car radiators. Experiments, validated with distilled water, explored various volume fractions (0.1 % to 1.0 %) and coolant flow rates (3 to 7 l/min). Results showed that increasing flow rates improved heat transfer, displacement heat transfer coefficient (HTC), and Nusselt number. Similarly, higher nanoparticle fractions enhanced heat transfer and HTC with minimal pressure drop. The radiator's thermal performance significantly improved with nanofluid use, but a reduction in HTC relative to pumping power was noted.

纳米流体的利用已在各个行业中得到广泛应用，包括交通、电子和能源。通过用纳米流体替代传统流体，可以提高传热速率。这不仅提高了发动机效率，降低了油耗，而且还可以设计出适应各种气候的更强大的发动机。这项研究的重点是在水-乙二醇基液中由氧化石墨烯和氧化硅纳米粒子组成的混合纳米流体，可应用于汽车散热器。使用蒸馏水进行验证的实验探索了各种体积分数（0.1% 至 1.0%）和冷却液流速（3 至 7 升/分钟）。结果表明，增加流量可改善传热、置换传热系数 (HTC) 和努塞尔数。同样，更高的纳米粒子分数增强了传热和 HTC，同时压降最小。使用纳米流体后，散热器的热性能显着提高，但 HTC 相对于泵浦功率有所降低。
