An Experimental Study on Hydro-Elasticity in Sloshing

Abstract

This research presents an experimental investigation on hydro-elasticity in sloshing experiment. Two models were tested. One of the models is ordinary, which is considered to be rigid wall made of plexi-glass. The other model has a flexible wall made of stainless steel. The two models were operated with identical excitation so that the influence of the elasticity can be detected. Four different filling levels were tested. The magnitude of excitation was 10% of the model longitudinal length. The models were operated only in surge motion. The models were tested with several excitation frequencies. The pressures were measured at 12 locations. It was shown that the effect of hydro-elasticity increases the magnitude of impact pressures.

Experimental investigation of dynamic pressure loads during dam break

“…3). With regards to the tank dimensions and PMMA mechanical properties, the tank walls were made of 20 mm thick PMMA sheets so that the walls could be considered rigid enough to avoid hydroelastic effects (Choi et al, 2012) (Abrahamsen and Faltinsen, 2011) while keeping a reasonable overall weight of the tank. The PMMA walls were transparent and the tank was assembled with a precision of 0.1 mm.…”

A set of canonical problems in sloshing. Part 2: Influence of tank width on impact pressure statistics in regular forced angular motion

“…They looked at the influence of minor variations in the mounting (flushness) of the sensors. According to Choi et al (2010Choi et al ( , 2012, mounting differences as small as 1 mm could induce a large influence on the pressure registers; Pistani and Thiagarajan did not, on the other hand, find such a strong dependence.…”

“…Interesting sensitivity analyses have also been conducted by Choi et al (2010Choi et al ( , 2012 and by Pistani and Thiagarajan (2012). They looked at the influence of minor variations in the mounting (flushness) of the sensors.…”
