摘要：
A numerical study was conducted in order to establish a set of preliminary design guidelines and performance criteria for three-dimensional subsonic wind tunnel contraction sections. Inlet geometries for both square and rectangular cross-sectional inlets were considered for a range of contraction ratios of 10-40. Wall geometries were defined using a single-parameter, matched cubic profile. Finite difference field solutions were developed for a potential flow model and the inlet performance quantitied in terms of mean flowfield distortion and adverse wall pressure gradients. A turbulent boundary-layer separation prediction is included based on Stratford's criteria.
