A photogrammetric flow visualisation technique used during a field experiment to study air motions around a ridge of high ground

Research output: Book/ReportOther report

Abstract

A photogrammetric flow visualisation technique used in a field experiment to study air motions around a ridge of high ground is described. Smoke generators fixed to helium filled balloons leave a smoke trail as the balloon rises. The smoke elements are photographed with two cine cameras. The analysis of the trajectories of smoke elements is described for general orientations of camera axis, thus allowing the three dimensional picture of the flow behaviour to be determined.
