Orbits in hydro vs. DMO simulations

Advisor: Dr. Lan Wang (NAOC)

Built an end-to-end pipeline to match hosts/satellites and track orbits from infall to coalescence. We find baryons drive more radial trajectories and shift collision-angle distributions toward larger values for massive hosts—implications for stellar halos and streams.

Viscoelastic convection (FENE-P)

Advisor: Prof. Xinhui Si (USTB) • Physics of Fluids

Implemented/validated OpenFOAM solvers for coupled Navier–Stokes & polymer stress; mapped how elasticity reshapes boundary layers and heat transport; emphasized convergence, diagnostics, and artifact rejection.
