In order to examine the pressure distribution at bodies under incident flow, simple models such as semi-spherical shells, streamlined bodies or cylinders are used in fundamental experiments. Incident flow of ‘blunt’ models may lead to flow separation.
Used in conjunction with it, the accessory makes it possible to record the pressure distribution around a cylinder under transverse incident flow. The cylinder is attached inside the intake pipe of it. The cylinder is fitted with a radial hole for pressure measurement and can be rotated around its axis. This means the pressure on the cylinder can be measured depending on the angle adjustment. The angle adjustment is detected electronically. The measured values are analysed using the software.
