Modeling and Computation

Reduced-order modeling, CFD, inverse methods, and data analysis.

Methods

• Quasi-one-dimensional conservation models incorporating area change, heat addition, wall friction, flow separation, and nonuniform mass and momentum fluxes.
• Iterative inverse formulations that combine measured wall pressure with conservation laws to infer exit Mach number and total-pressure loss.
• RANS and URANS simulations for multidimensional shock systems, boundary-layer interactions, nozzle flows, and exit-plane nonuniformity.
• Reduced-order modeling, system identification, POD, and CST-POD for compact representations suitable for prediction and control.
• Model validation against synchronized pressure, imaging, and computed flow-field data, with sensitivity analysis used to identify influential closure parameters.
