M. Obrien et Ae. Holdo, VISUALIZATION OF THE FLOW PATTERN GENERATED BY THE INTERACTION OF A CIRCULAR CROSS-SECTION INLET AND A CROSS-FLOW, Journal of wind engineering and industrial aerodynamics, 59(1), 1996, pp. 95-102
A series of flow visualisation experiments of the surface flow pattern
produced by a circular cross-section inlet mounted in a flat plate in
a cross-stream have been conducted. The results show a distinct and r
epeatable surface flow pattern characterised by a nodal stagnation poi
nt behind the inlet with adjacent saddle points lying symmetrically ei
ther side of the node. These general features of the flow pattern are
found over the range of inlet to free stream velocity ratios studied.
However, the relative location and extent of the flow domains are affe
cted by the change in the velocity ratio.
