Marine Engineering: Water Tunnel ENV 007
Sci-tech Water Tunnel Model ENV 007 is an important facility used to study flow around submerged bodies.
Although it has wide applications, it is primarily used to measure drag on submerged bodies, flow visualization, and conduct tests on propellers and cavitations studies. Water Tunnel is an important facility for the marine, ocean, navel architecture, civil, hydraulic, and mechanical and aerospace engineering laboratories of educational institutions. Water Tunnel for Education and Research has been designed to cater the needs of testing requirements of students and research community.
Item Description
It is a horizontal type closed recirculation water tunnel having a working section of size 200mm X 200mm and 800mm long. Water flow velocities unto about 0.9m/s can be obtained. The tunnel is built using stainless steel and mild steel with suitable painting to prevent corrosion. Honey combs and contraction are provided in the upstream of the working section to reduce turbulence in the flow. Transparent windows are provided in the working section to enable flow visualization and use of optical diagnostic measurement techniques such as
Lased Doppler Anemometry and Particle Imaging Velocimetry. The drive system comsists of an impeller and a
variable speed DC motor. Model support with incidence system is provided. A model Propeller and dynamometer for drag and torque measurements are provided to carryout propeller tests. The dye injection system with an array of needles is provided to carryout flow visualization tests. Basic instrumentation is provided for pressure and velocity measurements. The tunnel components are mounted on rigid structure to avoid vibrations.
