Stellar property statistics of massive haloes from cosmological hydrodynamics simulations: common kernel shapes

“…While such tensions exist for many of the derived LLR parameter values, we also find areas of congruence, particularly in the fundamental forms of mass-conditioned property kernels. Congruent results offer a necessary step of verification (e.g., Salvadori 2019), meaning that halo populations with consistent stellar MPRs emerge from independent solutions of the equations governing the complex, non-linear system of large-scale structure. A validation step using observational data must be done using observable proxies for the intrinsic true properties we use here.…”

Design and Optimization of a Low TSR H-Darrieus Turbine Based on Geometry Parameterization Through Joukowsky Transformation

“…The NACA 0021 airfoil was evaluated with three mesh types: refined, medium, and coarse. Using the Grid Convergence Index (GCI) approach by Celik, the discretization error was assessed [21]. Simulations were conducted, and the average power coefficient values were found for each mesh.…”
