Abstract This research work investigates the semi‐numerical analysis and heat transfer of MHD 2D, Copper Oxide, Magnesium oxide engine oil base nanofluid with consider effect dynamic viscosity convective boundary conditions (BCs). The BCs on an extensible surface are considered by flow system. We converted a set PDEs into NODEs applying appropriate transformations. Using HAM, we solve this dimensionless coupled equation one for temperature other velocity. impact various parameters both velocity demonstrated, such as slip parameter, magnetic parameter (MP), Eckert number (EN), PN, viscosity. In response to changes in developing factors, features, profiles (TPs) (VPs), analyzed simulated using physical description. results study add our knowledge how oil‐based nanofluids promote transmission offer practical advice thermal management engineering applications.
