| Summary: | A fluid-structure interaction phenomenon is an important consideration in several engineering fields.
When a tank truck is braking, turning or in collision, the liquid in the partially-filled tank will slosh or
even splash due to the oscillating of the unrestrained free surface of the liquid. The study of the
pressure impulse on the baffles and walls can provide data on the impacts acting on the tank and
baffles which can be used for simulating handling stability, especially for planes, rockets and
spacecraft. We consider the wave impact against a vertical baffle in four cases: (i) A vertical baffle at
free surface; (ii) A vertical baffle in front of a wall; (iii) A vertical baffle at a deck in front of a
seawall; (iv) A vertical baffle on the seabed in front of a wall. The mathematical formulation and the
boundary conditions for four cases of baffles which have different positions are presented using the
pressure impulse theory. We used a basis function method to solve the mathematical formulation, and
total impulse and moment impulse are investigated for each problem. The influence of the depth of
baffle penetration and the size of the impact region is also studied. We can see different of impact
pressure impulse for different case of baffle. We note that pressure impulse on the baffles almost same
for case (i),( ii) and (iii) for different length of baffles with same size of impact. However the pressure
impulse behind the baffles decreases when the length of baffle increases for case (ii) and (iii). For
case (iv), the pressure impulse on the wall and behind the baffles increases when the length of baffle
on the seabed increases |
