Quantifying acceptable mesh dependencies for computational investigations of airflows within rooms

摘要

Ignorance of mesh dependency can sometime be an embarrassment in numerical calculations. Mesh structures need to be developed to eradicate mesh dependency without compromising the finite computing resource and/or incurring large computational expense. For the inexperienced, mesh deployment often degenerated into a time-consuming iterative Procedure. To understand mesh influences, different mesh-structures have been applied to two Simple, yet typical, room-air-ventilation configuration. The predictions, using various mesh Regimes, have been compared with a datum result set: marks have been awarded according to The closeness of comparison to mesh-independent predictions.
