Descrição Geral

The Computer Controlled Closed Hydrodynamic Tunnel for High Speed, 150 x 150 mm, "HTHS150/150C", is a closed circuit cavitation tunnel with water flowing in the vertical plane. The water is circulated by a computer controlled variable speed axial propeller pump located at the bottom of the tunnel.

The unit includes several tunnel sections to reduce flow interference. A contraction upstream of the working area with a perfectly studied contraction curve contour ensures a well-developed water flow in the working area.

A honeycomb flow stabilizer is located in the section upstream of the shrinkage for greater flow uniformity in the working area.

The working area is located downstream of the shrinkage. It consists of a constant section section, where the models for testing are mounted. It is made with fused silica (quartz) windows on the front, back and top face for optical testing. This section includes a Pitot tube in its upper part to study static pressure, dynamic pressure and total pressure. It also includes a removable screen at the inlet to increase the turbulence of the flow.

A diffuser is included at the tunnel outlet to avoid the generation of turbulence that can damage the quality of the flow in the working area.

This Computer Controlled Unit is supplied with the EDIBON Computer Control System (SCADA), and includes: The unit itself + a Control Interface Box + a Data Acquisition Board + Computer Control, Data Acquisition and Data Management Software Packages, for controlling the process and all parameters involved in the process.
