Summary

Laminar forced convection in a double-pipe heat exchanger is studied numerically. An isothermal tube with periodic enhancements (promoters) is placed concentrically inside an insulated circular tube. Pressure drop and heat transfer characteristics of promoters are obtained at various geometric and flow conditions. These are compared to an unenhanced (circular) tube annulus of identical length and heat transfer surface area while the mass flow rate and the Reynolds number are kept the same.
