I was interested in a model to evaluate the temperature change of water flowing through a tube immersed in a tank of water.  I modeled 5 turns of a helix with a radius of 30 mm, pitch of 23 mm, aluminum tube OD of 10 mm with a 1 mm wall thickness. <\/span>I used Excel to create a file of points on the helix and imported that file into DesignModeler as a 3D curve. <\/span> <\/span>A line body represents the water flowing in the tube. The flow rate is 1 kg\/s and the input temperature is 100 C. A solid body represents the tube. A convection BC represents the outside of the tube losing heat to the outside water at a temperature of 25 C. A second convection BC represents the inside of the tube taking heat from the fluid inside the tube.<\/span><\/p>\n

After I solved this system, I plotted the temperature of the water in the tube.<\/span><\/p>\n

I was interested to learn that I could obtain results from the Steady State Thermal system block that I initially thought I would have to build a much more complicated CFD model to get similar results.<\/span><\/p>\n
