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

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.
