  • Patent number: 10929577
    Abstract: Techniques for autonomously modeling a two-phase cooling architecture are provided. In one example, a computer-implemented method can comprise generating, by a system operatively coupled to a processor, a reduced physics model based on a profile of a heat source and a parameter of a cooling structure. The reduced physics model can provide an output. Also, the computer-implemented method can comprise generating, by the system, a full physics model based on the output. The computer-implemented method can further comprise combining, by the system, the reduced physics model and the full physics model to define an architecture that achieves a flow distribution of a coolant.
