Ahmed M.I. 54789424300 7003976733 7005372503 15922129900 Delta wing aircraft; Ducts; Ethylene; Ethylene glycol; Finite volume method; Heat convection; Heat transfer; Nanoparticles; Reynolds number; Shear stress; Vortex flow; Vorticity; Enhancement of heat transfer; Heat Transfer enhancement; Laminar forced convections; Nanofluids; Nanoparticle concentrations; Temperature-dependent properties; Two phase; Vortex generators; Nanofluidics Laminar forced convection heat transfer and nanofluids flow in an equilateral triangular channel using a delta-winglet pair of vortex generators is numerically studied. Three nanofluids, namely; Al2O3, CuO, and SiO2 nanoparticles suspended in an ethylene glycol base fluid are examined. A two-phase mixture model is considered to simulate the governing equations of mass, momentum and energy for both phases and solved using the finite volume method (FVM). Constant and temperature dependent properties methods are assumed. The single-phase model is considered here for comparison. The nanoparticle concentration is assumed to be 1% and 4% and Reynolds number is ranged from 100 to 800. The results show that the heat transfer enhancement by a using vortex generator and nanofluids is greater than the case of vortex generator and base fluid only, and the latest case provided higher enhancement of heat transfer compared to the case of a base fluid flowing in a plain duct. Considering the nanofluid as two separated phases is more reasonable than assuming the nanofluid as a homogeneous single phase. Temperature dependent properties model provided higher heat transfer and lower shear stress than the constant properties model. � 2014 Wiley Periodicals, Inc.
