Abstract | The cavitation flow of the cartridge pilot-operated relief valve’s main valve port was numerically simulated and studied using Computational Fluid Dynamics (CFD) in our research, and the relief valve structure was modified to decrease cavitation noise. These findings indicate that cavitation in the relief valve occurs primarily downstream of the main valve port and is linked to the wall. The cavitation generation is influenced by the jet at the valve port. The closer the high-speed jet at the valve port is to the valve’s inner wall, the more readily cavitation occurs. Conversely, less cavitation is observed. This paper reports the effects of the forms and parameters of the main port structure on the jet angle and morphology of cavitation. The annular groove structure of the spool has a considerable influence on the cavitation attached to the spool and the valve sleeve wall, whereas the outlet position of the relief valve mostly affects the intensity of cavitation near the valve sleeve wall. Based on this, an optimized structure of the relief valve was designed, with which the maximum vapor volume fraction and total vapor volume of the cavitation flow were considerably decreased for various inlet pressures and spool openings. The experimental results show that, following optimization, the noise of the relief valve drops dramatically, confirming that optimizing the structure has a beneficial impact on decreasing cavitation noise. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
