hi every body
please I have reearch about the natural convection heat transfer from helically coiled tubes under constant wall heat flux density, with vertical axis in water was carried out. The effect of helix diameter and helix pitch on the local and average Nusselt number have assessed. A complex influence of the two parameters on Nusselt number must be found. The heat transfer device was immersed in a cylindrical enclosure with vertical axis. The proximity of the wall enclosure must be found to influence the buoyancy induced flow profile and as a consequence, Nusselt number value. d of pipe =0.02m D of coil=0.16 m Pitch=0.05 m Diameter of tank =0.6 m No. of turn=9.5 coil inside tank My question how Can I solve the model because I solved it in Fluent , CFX, and comsol but I didnt have any result I need to advice me what should I do Thanks |
