斜航船体まわりの流場計測

抄録

In this research, the flow field measurement around ship hull at incidence was made by using five hole Pitot Tube which was operated by automatic flow measuring system. At first, the paper describes the developed system for flow measurements in circulating water channel. The system is consist of two parts: the sensor controlling system, a kind of a robot manupulator, and the data acquisition system. The system enables measuring of flow velocity vector around ship model automatically using several microcomputers which are cominucated through RS232C channel. The results of flow field measurment around ship hull at incidence are shown, at whole of the back side region from fore to aft peak. The vortex separeted at fore part travels with the outer potntial flow. Therefore, the path line of the vortex is different from that of full ship as a tanker model.
