چکیده
Recently, the vacuum technology has gained a significant relevance in many areas of basic research and applied science. Low-pressure environment of various quality is in common use in the top technology industrial applications. In the most cases, the leaks are the most common sources of deterioration in quality of vacuum. Therefore, the leak detection and consequential leak localization become as a joint part of researcher’s and engineer’s work. A new method suitable for low vacuum region and large vacuum leaks was developed. The method focuses on detection of leaks from vacuum flanges. A special flexible reservoir is put on the flange with a possible leak and its volume is pumped through the leak. By the atmospheric pressure, the reservoir is deformed and through this fact, the leak presence is confirmed. An advantage of this method is a low cost and easy to use.

INVERSE FREQUENCY RESPONSE ANALYSIS FOR PIPELINES LEAK DETECTION USING THE PARTICLE SWARM OPTIMIZATION
Inverse Transient Analysis (ITA) is a powerful approach for leak detection of pipelines. When the pipe transient flow is analyzed in frequency domain the ITA is called Inverse Frequency Response Analysis (IFRA). To implement an IFRA for leak detection, a transient state is initiated in the pipe by fast closure of the downstream end valve. Then, the pressure time history at the valve location is...
