Abstract
A methodology for local solution-adaptive mesh refinement in computational fluid dynamics (CFD) using cell-level and global kinetic energy balances is formulated and tested. Results are presented for a two-dimensional steady incompressible laminar lid-driven cavity at a Reynolds number Re = 1000. It is demonstrated that local kinetic energy imbalance correlates with local solution accuracy, that normalized global imbalance is an appropriate criterion for halting mesh refinement, and that a specified level of accuracy is realized at lower computational effort using local refinement compared to a uniform finer mesh.
