Kavitace v armatuře

Abstract

Thesis is focused on measuring cavitation in the control armature which is developed by company ARMATURY Group a.s. There is research about cavitation in control valves based on large amount resources. Hydraulic circuit for measuring flowing in control armature was put together and rated pressure recovery factor FL was computed. After this were measured p-Q characteristics during small openings of armature for numerical simulation in FLUENT. During this step just inception cavitation was reached. At the end of thesis are simulation-measuring comparisons and computed cavitation index too.
