Abstract
The present article about the high speed water tunnel facility at the Indian Institute of Science, Bangalore, provides a general description of the tunnel circuit, and brief reports on the performance of the facility and some typical results from investigations carried out in it. A unique aspect of the facility is that it has a horizontal resorber in the form of a large cylindrical tank located in the lower leg of the circuit. The facility has been used, among other things, for flow visualization studies, and investigations on marine propeller hydrodynamics and “synthetic cavitation”. The last topic has been primarily developed at the Indian Institute of Science and shows considerable promise for basic work in cavitation inception and noise.

Additional information
The Indian Institute of Science High Speed Water Tunnel owes its existence to the vision of Professor N S Govinda Rao. The facility was designed by the late Mr Nanjundaswamy under the supervision of Professor K Seetharamaiah who was instrumental in its fabrication and installation. All the tunnel components except for the main motor and pump were fabricated by M/s Tungabhadra Steel Products Ltd., Hospet, Karnataka. The financial support for the design, fabrication and installation of the high speed water tunnel facility was given by the Central Board of Irrigation and Power, Government of India. The financial grant for the construction of the building to house the facility has been provided by the University Grants Commission, New Delhi. Financial support for the addition of the open-jet test section and procurement of all the instruments listed has been given by the Department of Electronics/Electronics Commission under its technology development projects.
