摘要： PROBLEM TO BE SOLVED: To provide a novel method for detecting a leakage position using an AE when a fluid is leaked from a bottom plate.
SOLUTION: Oil 3 under storage is removed or discharged as gas from a gas discharge pipe 6 so as to lower a liquid level of the oil 3, at first. Then, a discharge amount from the discharge pipe 6 is increased to reduce internal pressure in a tank 1. The AE is monitored by respective AE sensors 7A, 7B, 7C, and the discharge of the gas from the discharge pipe 6 is stopped at the time point when the AE is not detected accompanied to the leakage. The gas is filled thereafter through the discharge pipe 6. The internal pressure is thereby increased again to start generation of the AE accompanied to the leakage, at the time point when reaching to a prescribed pressure. The start of the generation of the AE is monitored by the each AE sensor, and a generation position of the leakage is specified based on a difference in a generation start time of the AE.

摘要： PROBLEM TO BE SOLVED: To optimize the form of a beat exchanging member such as a finned tube capable of improving a heat exchanging efficiency by analyzing the configuration of ice coating to the heat exchanging member such as the finned tube in an LNG vaporizer as well as an open rack type vaporizer, and analyzing the correlation between the configuration of the finned tube and the configuration of the ice coating. SOLUTION: A prescribed horizontal sectional form at the prescribed height position of the finned tube is used as a model to preset joint groups and element point groups representing the configuration of the ice coating to the form. Temperature on the ice coating surface is obtained by a limited element method, a limited difference method or a boundary element method by employing heat flux on the ice coating surface or the like as input conditions. The configuration of the ice coating is repeatedly converged while it is corrected so that the temperature on the ice coating surface becomes ice coating temperature to analyze the configuration of the ice coating on the finned tube, and to examine the form of the model and the configuration of the ice coating on its surface.
