Cavitation is the structure of water foam in a liquid molecules and consecutive partition in its flow. When the vapour pressure at certain temperature is less than the absolute pressure the air molecules are formed. Cavitation processes have lots of troublesome in turbo machinery reducing capability and generating noise. The process of control measures is considered when the negative approaches are done to control it. The simulations are done by varying the diameter of the circular disk by choosing some fixed cavitation numbers and by varying flow pressures. The tendency of the cavity such as diameter, length, and drag coefficient are to be studied and compared with the laboratory information or data and diagnosticsimilarity. The analysis which is done is based on the pressure and velocity as we observe from the graphs pressure contours where the fluid is entering the step part in the nozzle there is an increase in pressure at one phase, but as we observe it clearly there in a low pressure area that is created in between the flow where there is a gradual pressure drop. This low pressure area is the region where the bubbles are going to form and when these bubbles meet the high pressure region, due to the pressure difference these bubbles are going to explode and damage the internal surfaces. Plot the velocity contours and static pressure contours at different pressures (2 bar, 3 bar and 5 bar), increase in pressure and velocity the value of cavitation increases. [ABSTRACT FROM AUTHOR] |
