The hybrid base solvent water (HO) and ethylene glycol (CHO) are highly use in industrial applications due to excellent solvability. Addition of hybrid nanoparticles (GO-MoS) augments the thermal conductivity of these fluids which ultimately make them very productive. Hence, the current study aims to develop and investigate the novel hybrid nanofluid model (GO-MoS)/(CHO-HO) through MRW (moving riga wedge) and SRW (static riga wedge) cases. The traditional Falkner Skan Model (FSM) is modified using the novel effects of solar radiations, internal heating source and fixed magnets which is associated to the concept of Riga wedge. Further, the improved thermal-physical characteristics of hybrid nanofluids will use to enhance the thermal productivity. A mathematical model is developed for the flow situation of (GO-MoS)/(CHO-HO) and treated numerically. The results furnished through graphical way and comprehensive discussion provided. It is examined that the movement of (GO-MoS)/(CHO-HO) reduced for MRW and observed the rapid velocity near the surface. The heat generating source and solar radiations number enhanced the performance of (GO-MoS)/(CHO-HO) and better predicted ranges for these parameters are observed from [Formula: see text] and [Formula: see text]. Moreover, the boundary layer region becomes thin for heating source and it increased for stronger solar radiation effects. The nanoparticle amount of GO and MoS enhanced the model utilization while higher magnetic number and MRW number [Formula: see text] controlled the thermal boundary layer. The results for the model dynamics are noticed dominant for MRW case as compared to SRW case.
混合基溶剂水（HO）和乙二醇（CHO）因其出色的溶解性而在工业应用中得到广泛使用。添加混合纳米颗粒（GO-MoS）可提高这些流体的热导率，最终使其具有很高的生产效率。因此，当前的研究旨在通过移动里加楔（MRW）和静止里加楔（SRW）情况来开发和研究新型混合纳米流体模型（GO-MoS）/（CHO-HO）。传统的福克纳-斯坎模型（FSM）通过太阳辐射、内部热源和固定磁体的新效应进行了修正，这些效应与里加楔的概念相关。此外，混合纳米流体改善的热物理特性将用于提高热生产效率。针对（GO-MoS）/（CHO-HO）的流动情况建立了数学模型并进行了数值处理。通过图形方式给出了结果并进行了全面讨论。研究发现，对于MRW，（GO-MoS）/（CHO-HO）的流动减小，并观察到表面附近速度较快。发热源和太阳辐射数提高了（GO-MoS）/（CHO-HO）的性能，并且从[公式：见原文]和[公式：见原文]观察到这些参数的较好预测范围。此外，对于加热源，边界层区域变薄，而对于较强的太阳辐射效应，边界层区域变厚。GO和MoS的纳米颗粒量提高了模型的利用率，而较高的磁数和MRW数[公式：见原文]控制了热边界层。与SRW情况相比，模型动力学结果在MRW情况下更为显著。
