| Research Abstract |
The liquid sloshing phenomenon of oil storage tank was excited by the 2003 Tokachi-oki Earthquake. This phenomenon caused severe damage to oil storage tanks at Tomakomai igniting fire and sinking floating roofs. After this accident, verification of various, dynamic behavior of a floating roof due to liquid sloshing have been begun and it has been desired to verify it with the tank at the real scale level. Then, we propose the experiment method of generating the sloshing phenomenon in the floating roof tank using a real tank. This method uses the excitation equipment of the liquid sloshing phenomenon by the Wave Generator with air cylinders which is set up and moves the fluid in the tank. As a result, we succeeded in the generation of the liquid sloshing in a real tank and obtained appropriate damping factor of the liquid sloshing.
