Hydrodynamic Performance of the Large Cavitation Channel (LCC) (original) (raw)

High Reynolds number experimentation in the US Navy's William B Morgan Large Cavitation Channel

Measurement Science and Technology, 2005

The William B Morgan Large Cavitation Channel (LCC) is a large variable-pressure closed-loop water tunnel that has been operated by the US Navy in Memphis, TN, USA, since 1991. This facility is well designed for a wide variety of hydrodynamic and hydroacoustic tests. Its overall size and capabilities allow test-model Reynolds numbers to approach, or even achieve, those of full-scale air-or water-borne transportation systems. This paper describes the facility along with some novel implementations of measurement techniques that have been successfully utilized there. In addition, highlights are presented from past test programmes involving (i) cavitation, (ii) near-zero pressure-gradient turbulent boundary layers, (iii) the near-wake flow characteristics of a two-dimensional hydrofoil and (iv) a full-scale research torpedo.

CAVITATION AND ITS EFFECT IN FLUIDS A Technical Seminar Report Sarthak Das Roll # ME201518114

The effect of physical wear and losses in the case of fluid domain has been an effective criterion to have analysis. Cavitation in a certain way causes the formation of voids and surface fatigue on the surface of metals that are either exposed as a passage or as a part of fabrication of external body of submarines, turbines, pumps, pipes, underwater missiles etc. in cavitation process there is formation and accumulation of bubbles around the walls of the parts and as these bubbles collapses it creates a high energy which creates high energy shock waves inside the liquids causing the erosion of material. In cases of fluidic means of transportation or passages the wear in materials in engineering context can cause high cost and difficult serviceability of the parts therefore it is very important to analyse and have a proper design of the dynamic parts to avoid this undesirable phenomenon. Generally, the major losses through cavitation only takes place when it is inertial, that is where continuous formation and collapse of bubbles takes place. However, this can even be controlled by considering the following steps such as  Reducing the temperature of fluid.
