...Santinath Bairagi; Ranendra Roy; Bijan Kumar Mandal In this study, an attempt has been made to carry out a numerical investigation using water-based Al 2 O 3 nanofluid, flowing through a circular tube under constant inlet temperature and constant heat flux conditions in the laminar flow regime...

... performance. So, gases, such as carbon dioxide, helium, nitrogen, oxygen, hydrogen, methane, neon, and air, are considered in the present study, which flow through a thick-wall stainless steel pipe under a laminar flow regime. The temperature-dependent thermo-physical properties of the gas are considered...

... helical tubes are used to investigate the coil side heat transfer rate and friction factor of non-Newtonian nanofluids under laminar flow conditions. For the numerical analysis, single-phase approach with commercial software ansys-fluent-19 has been utilized. Investigations encompass generalized Reynold...

... laminar flow. The ternary nanoparticles were synthesized using the sol–gel technique and characterized by X-ray diffraction (XRD), scanning electron microscope (SEM), and Fourier transform infrared spectroscopy (FTIR). The stable ethylene glycol-based ternary hybrid nanofluid was prepared and its...

... conclusions were presented. Erek et al. [ 5 ] used computational fluid dynamics (CFD) software to investigate the effects of geometrical parameters on the performance of the plain fin-and-tube heat exchangers with circular and elliptical tubes for steady, incompressible and laminar flow, and they suggested...
