TESTS OF AN ASYMMETRICAL BAFFLE FOR FUEL-SLOSHING SUPPRESSION

Abstract

Damping effectiveness of a new type of fuelsloshing baffle is presented in terms of measured frequency response of a cylindrical tank undergoing forced translational motion. The results are given in the form of damping ratio, fundamental natural frequency, and coupled frequency so that the dynamic response functions which represent fuel dynamics are defined. The baffle by virture of its asymmetrical form is shown to couple the fundamental sloshing mode with the second symmetrical mode in such a way that the effective damping is considerably higher than the damping of conventional ring-type baffles of equal area.
