Transition Prediction for Hybrid Laminar Flow Control Flight Test Considering Geometric Uncertainties
Publisher: ASCE
Abstract: Due to its significant capability for energy and environmental sustainability, the hybrid laminar flow control (HLFC) shows excellent technical appeal for civil aircraft. To use computational tools to speed up the HLFC ...
Surface Roughness Effects on Unsteady Transition Property over a Pitching Airfoil
Publisher: ASCE
Abstract: The characteristics of unsteady boundary-layer transition on a small-amplitude pitching NACA0012 airfoil are investigated using the γ−Reθt¯−Ar transition model, which consists of the γ−Reθt¯ transition model and the roughness ...
A Galilean Invariant Variable–Based RANS Closure Model for Bypass and Laminar Separation Bubble–Induced Transition
Publisher: ASCE
Abstract: A one-equation Reynolds-averaged Navier-Stokes (RANS) closure model has been established for bypass transition and laminar separation bubble (LSB)–induced transition. A new local indicator is proposed to describe the ...
