NUMERICAL SIMULATIONS OF LAMINAR BACKWARD-FACING STEP FLOW WITH FEMLAB 3.1

摘要

The paper presents 2-D numerical simulations of laminar backward-facing step flow using the FemLab 3.1 modeling package. Results demonstrated that primary reattachment lengths predicted by FemLab were in close agreement with experimental data up to step Reynolds number Re_h =300. Also, dimensionless velocity profiles along the channel height calculated by FemLab were successfully compared with the experimental data.
