Turbine engines, like other complex systems, are composed of many subsystems featuring a wide variety of physics and extreme behavior. From a simulation and analysis perspective, this means there are many input dimensions and the system suffers from the curse of dimensionality: i.e., it requires an exponential increase in sampling to cover the design space for the same level of resolution.
With existing tools, the Jet Engine OEM couldn’t scale up their engine performance exploration and characterization efforts without an exponential increase in simulation resources. Particularly challenging was high fidelity CFD simulation of transient thermal events.
By developing novel, faster and more efficient Design of Experiment and emulation tools, SmartUQ was able to help make sampling and simulation requirements manageable while maintaining or improving model accuracy.
