    EFFECT OF NANOPARTICLE SHAPE ON NANOFLUID FLOW IN CONICAL HELICAL TUBE
    (2024) Altunay, F.M.; Ali, M.A.M.; Gurdal, M.; Pazarlioglu, H.K.; Arslan, K.; Gedik, E.
    The nanofluid flow in a conical helical tube was numerically investigated. The study has been carried out in three-dimensional laminar flow (85.73 <= De <= 175.55) condition. Al2O3-water nanofluid with different nanoparticle volume fractions (1.0%, 2.0%, 3.0%) has been used as the working fluid in the numerical analyzes. In addition, studies were carried out for blade, platelet, and cylindrical nanoparticle shapes. The average Nusselt numbers and the average Darcy friction factors have been used to estimate the flow and heat transfer performance of nanofluid flow in the conical helical tubes. Numerical results of the study have been presented as the variation of average Nusselt number and average Darcy friction factor with Dean number, nanoparticle shape, and nanoparticle volume fraction. As a result, the highest convective heat transfer performance has been obtained for the cylindrical nanoparticle shape of the %3.0 Al2O3-water nanofluid.
