Numerical analysis of heat transfer and nanofluid flow in a triangular duct with vortex generator: two-phase model

Laminar forced convection heat transfer and nano-fluids flow in an equilateral triangular channel using a delta-winglet pair of vortex generators is numerically studied. Three nanofluids, namely; Al2O3, CuO, and SiO2 nano-particles suspended in an ethylene glycol base fluid are examined. A two-phas...
