Study of flow around a sphere in a hydraulic test tunnel
Abstract
A three dimensional study of trajectory around a sphere is described. A special software program is developed to take into consideration the time and space parameters involved. A second study is carried out to establish a method of calculating, with flow corrections, the average flow around a sphere in the presence of side walls. Qualitative visualizations of the flow are provided. The instabilities within the wake are characterized. The need for improvements in three dimensional laser lighting is stressed. Light sources adapted to such purposes need to be developed.
