Multi-fidelity multidisciplinary whole engine thermo-mechanical design optimization
Multi-fidelity multidisciplinary whole engine thermo-mechanical design optimization
Traditionally the optimization of a turbomachinery engine casing for tip clearance has involved either 2D transient thermo-mechanical simulations or 3D mechanical simulations. The following paper illustrates that 3D transient whole engine thermo-mechanical simulations can be used within tip clearance optimizations and that the efficiency of such optimizations can be improved when a multi-fidelity surrogate modeling approach is employed. These simulations are employed in conjunction with a rotor sub-optimization utilizing surrogate models of rotordynamics performance, stress, mass and transient displacements and an engine parameterization.

Abstract
Traditionally the optimization of a turbomachinery engine casing for tip clearance has involved either 2D transient thermo-mechanical simulations or 3D mechanical simulations. The following paper illustrates that 3D transient whole engine thermo-mechanical simulations can be used within tip clearance optimizations and that the efficiency of such optimizations can be improved when a multi-fidelity surrogate modeling approach is employed. These simulations are employed in conjunction with a rotor sub-optimization utilizing surrogate models of rotordynamics performance, stress, mass and transient displacements and an engine parameterization.
