LAMINAR FLOW COMPUTATION AROUND WING-BODY JUNCTIONS - FLOW VISUALISATION BY USE OF COMPUTATIONAL RESULTS

The laminar shear flow at the junction of a wing with a flat plate is considered. The simplest case, the flow past a symmetric foil on a flat surface at zero incidence to a uniform flow, is selected. A numerical method for the solution of the Navier-Stokes equations has been employed to calculate the flow around this simple model geometry with the objective of studying flow phenomena associated with junctions in practical configurations. The computed results for two foils are presented. Computed streaklines and limiting streamlines are shown as well as pressure and velocity distributions to visualise the flow fields.
