RISPoppet Valve Stability
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The analysis presented in this paper shows that poppet valve instability can be caused by interaction of the fluid delivery line dynamics with those of the spring-mass of the valve. The ...
Intrusion within a Simulated Water Distribution System due to Hydraulic Transients. II: Volumetric Method and Comparison of Results
Publisher: American Society of Civil Engineers
Abstract: A pilot-scale test rig was used to simulate intrusion behavior associated with hydraulic transient initiated by rapid valve closure in a water distribution system. In Part I, the test rig apparatus and operating conditions ...
Intrusion within a Simulated Water Distribution System due to Hydraulic Transients. I: Description of Test Rig and Chemical Tracer Method
Publisher: American Society of Civil Engineers
Abstract: A pilot-scale test rig was designed and constructed to simulate intrusion behavior associated with hydraulic transients initiated by sudden events such as rapid valve closure or uncontrolled change in on/off pump status ...
