The cavity contains one heat source and one heat sink, and the cavity walls are adiabatic. The fluid is a water-based hybrid nanofluid. The temperature in the cavity is randomized using a random function. The main parameters, including volume fraction of nanoparticles, temperature type, and type of hybrid nanofluid, are varied and analyzed using the finite volume method. The numerical results are compared with previous studies, and good agreement is observed. The obtained results show that the addition of nanoparticles significantly enhanced the heat transfer in the cavity (φ=0.1%). In addition, the larger Rayleigh number, the more obvious the influence of temperature type. Also, the average Nusselt number increases as the volume fraction increases, and the best results are obtained from the (Ag-TiO2)/water hybrid nanofluid.","PeriodicalId":51672,"journal":{"name":"Nanoscience and Technology-An International Journal","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135596741","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nanotechnology has provided exciting new materials for enhancing engineering devices, including electromagnetic permeable nanofluids. The Darcy-Forchheimer model is employed to define the porous medium. The performance of both metallic and oxide nanoparticles is studied as they are dropped in water, which is a base fluid. The homogenous Tiwari-Das model is adopted. The governing conservation equations are solved using the MATLAB bvp4c shooting method. Verification of earlier solutions for the clear fluid without the porous matrix is conducted. Graphical visualization of the velocity is conferred for the impact of various parameters such as using different nanoparticles, solid volume fraction, Hartmann and Reynolds numbers, angle between the two plates, porous parameter, and inertial parameter. It is found that the silicon oxide nanoparticle produces the optimal velocity, and the silver nanoparticle gives the minimum velocity. Upon increasing the solid volume fraction, the flow is reduced, and the presence of porous matrix does not alter the flow remarkably.","PeriodicalId":51672,"journal":{"name":"Nanoscience and Technology-An International Journal","volume":"18 1","pages":""},"PeriodicalIF":1.3,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73327842","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
