HOW TO USE BOTH FLOW SIMULATION AND THERMAL ANALISIS IN A HEAT EXCHANGER

Tutorial by Dmitriy Babych
Small

Heat exchanger

  1. Step 1:

    Create simplify heat exchanger by this drawing

  2. Step 2:

    In SW you get model. Turn on “Flow Simulation” module

  3. Step 3:

    Create new flow project

  4. Step 4:

    On “type of task” page turn on “heat conduction in solids”

  5. Step 5:

    On page “fluid” and add “water”

  6. Step 6:

    On page “material” add material aluminum. All other parameters are default

  7. Step 7:

    Create plugs in holes of detail

  8. Step 8:

    Create boundary conditions on detail holes.
    Create a parameter of the mass flow 5kg/s at the entrance to casing. Temperature is 573K

  9. Step 9:

    At the out of casing, create a boundary condition "ambient pressure"

  10. Step 10:

    At the entrance to tube create a boundary condition "incoming speed" 1m/s and temperature is 278K

  11. Step 11:

    At the outlet of the pipe, set the boundary condition "coming out speed" 1m/s

  12. Step 12:

    start the calculation

  13. Step 13:

    After calculations add results "trajectory of the flow" – flow temperature, type – tubes, faces of the inner pipe (incoming, exiting), number of points - 100

  14. Step 14:

    add results "trajectory of the flow" – flow temperature, type – tubes, faces of the inner pipe (incoming, exiting), number of points – 20

  15. Step 15:

    You get result!!
    Temperature rises by approximately to 30 degrees.
    I do not know the parameters of your heat exchanger, so the results are approximate. This is just an example, based on it, you can make similar calculations.
