摘要

An hp-adaptive predictor-corrector split (PCS) finite-element model (FEM) is used to simulate subsonic, transonic turbulent compressible flow. The hp-adaptive algorithm is based on mesh refinement and increasing spectral order to generate accurate simulation results with an exponential converge rate; the PCS projection method employs a fractional step FEM, and it has been shown to produce accurate results over a wide range of flow speeds. A k-ω turbulent closure scheme is used in conjunction with the turbulent form of the Navier-Stokes equations. The hp-FEM PCS system is currently being combined with Los Alamos National Laboratory's spray and chemistry models to advance the accuracy and range of applicability of the KIVA combustion model and software. Test cases results for subsonic flow and transonic flow around NACA0012 airfoil are presented, and good agreement with experimental data is observed. Simulations are conducted for full-scale and microscale airfoils under different thermal effects, and the aerodynamics performance under different conditions are compared.
