I am a CFD researcher focused on physically grounded models, robust numerics, and reproducible workflows for engineering applications.

My work combines turbulence modeling, solver development, and data-driven analysis. I build concise tooling around simulation workflows to keep results transparent and practical for decision making.

Publications

  • Application of Hybrid-Temporal LES to Shock-Induced Boundary Layer Separation in Hyperloop Flows

    Evaluates hybrid-temporal LES for shock-induced boundary layer separation in hyperloop-like flows and shows stable, computationally practical improvement over baseline RANS for drag and separation prediction near choking conditions.

  • Assessment of Under-Resolved Hybrid Scale-Resolving CFD Methods for Transonic Buffet over Blunt Bodies

    Assesses low-resolution hybrid RANS-LES approaches for blunt-body transonic buffet and reports improved transient/separation prediction versus RANS with manageable computational cost.
