    3d Numerical Investigation of Flow and Heat Transfer Characteristics in Smooth Wavy Fin and Elliptical Tube Heat Exchangers Using ARW Vortex Generator
    (Department of Mechanical and Production Engineering (MPE),Islamic University of Technology(IUT), Board Bazar, Gazipur, Bangladesh, 2017-11-15) Sabbir, Shah Mohammad; Chowdhury, Sadat Hasan
    3D computational analysis was performed to investigate heat transfer and pressure drop characteristics of flow in SWFET (Smooth Wavy Fin-and-Elliptical Tube) heat exchanger with VGs (vortex generators). The numerical model was well validated with the available experimental results. Numerical results illustrate that adding vortex generators and changing the shape of tube can bring about further heat transfer enhancement. Through careful adjustment of the position with respect to the elliptical tube, type and attack angle of vortex generators. Numerical study shows that adding vortex generator and elliptical shape of tube enhances heat transfer characteristics.
