Release 12 - What's New in Depth: Leak Detection

21 March, 2018


From aerospace & defense to gaming PC’s, liquid cooling has applications across numerous industries. The theory behind it is simple, by taking advantage of a liquids higher specific heat, density and thermal conductivity when compared to air you can remove more heat from a system for a given volumetric flow rate.

Whilst 6SigmaET makes setting up a liquid cooling case as simple as possible from a user perspective, there is an ever-present threat of leaks. This can be caused by several factors, but usually, the main suspect is ill-fitting geometry. 

In a previous blog, we discussed how it is good practice to plot density to determine whether a liquid cooling model is leaking. However, knowing a model is leaking is just the tip of the iceberg. Determining where it is leaking from is the main question and something that, in the past, a user had to answer for themselves through a process of inspection, trial and error and sometimes even luck. But not anymore, as of Release 12 we have introduced leak detection.

So, how does it work? First, you solve an iteration and plot density to determine if a leak is present. Next, right click on the ‘Pumped Supply’ object and add a new ‘Flow Solution Region’. 

Then, you can incrementally increase the ‘Propagation Distance’ until the location of the leak becomes visible.

Having identified the location of the leak you can then take corrective action such as making sure objects overlap to form a good seal, adding solid obstructions to plug holes or adding extra grid around particularly complex CAD pipework.
