Abstract

The characteristics of a flow around a cubic model are experimentally studied by a wind tunnel test. The flow around the model was measured by PIV method. And simultaneous multi-pressure measurements on the model surface were also performed. By using this two method synchronously, simultaneous data set of the flow and the wind pressure on model were obtained. As a result of the measurements, instantaneous reattachment was observed on the roof surface of the cubic model.
