“How to Stir your Coffee Perfectly?”

THE CHALLENGE

We are CAE engineers. But we are also coffee lovers. Combine these two and what happens? A simulation based answer to your everyday question: "How to perfectly stir my coffee?" A very simple question, but yet the answer requires complex modelling. The problem has two main difficulties:
  • There is a moving part
  • The problem involves the mixing of two fluids

     

OUR SOLUTION

Infinity is the way to go! In the video the final result of the work can be seen. The centrifugal force will push the milk upwards, where it can better interact with the spoon. The back and forth motion and the infinity movement causes mixing by causing complex turbulence flow. Off all three cases it is seen that the infinity technique is most effective.
