Implementation Code for Paper "Application of kernel POD pre-image recovery methods to nonintrusive nonlinear reduced order model of steady-state velocity magnitude field in the RPV lower plenum"

This dataset contains the implementation code for constructing non-intrusive nonlinear reduced order model (ROM) using kernel proper orthogonal decomposition (POD) combined with three different pre-image recovery methods proposed by Mika, Rathi, and Kwok. The code corresponds to the methodology proposed in paper and can be used to reproduce the kernel POD-based nonlinear ROM results.
