    Heat exchanger with helical baffles

    Michael Fidel

      I'm currently working on a project of heat exchanger with helical baffles with both water entering in the tube and the annulus side. Dimensions of the geometry is used attached here. I am just confused because only a little temperature change for both tube and annulus side are present. Is it just because the dimensions are too small, or did i miss to consider some of the parameters? I


      DPHE size:

      Material: Stainless Steel

      Inner Tube Internal Dia - 10 mm

      Inner Tube Thickness    - 1 mm

      Outer Tube External     - 16mm

      Outer Tube Thickness    - 1mm

      Annulus side baffles spacing - 100-25mm

      Heat exchanger length         - 100mm


      Pitch (40deg) - 10.908295205305
