High-fidelity simulations of mixing and combustion processes are computationally demanding time-consuming, hindering their wide application in industrial design optimization. This study proposes projection-based reduced order models (ROMs) to predict spatial distributions physical fields for multi-species problems a fast accurate manner. The developed ROMs explore the suitability various regression methods, including kriging, multivariate polynomial (MPR), k-nearest neighbors (KNN), deep...
In advanced aero-engines, kerosene is often transversely injected into the combustor at supercritical pressure, where shorter jet penetration depth may result in poor mixing and local hot spots near wall. Elevating nozzle proposed to remedy these issues, flowfield complexity increases as a of intricate interactions among jet, crossflow, stack wake. The distinct flow dynamics elevated dodecane jets crossflow (EJICF) pressure are numerically investigated using large eddy simulation. effects...
