abstract = {<p style="text-align: justify;">In present paper, the locomotion of an oblate jellyfish is numerically
investigated by using a momentum exchange-based immersed boundary-Lattice
Boltzmann method based on a dynamic model describing the oblate jellyfish.
The present investigation is agreed fairly well with the previous experimental
works. The Reynolds number and the mass density of the jellyfish are found to
have significant effects on the locomotion of the oblate jellyfish. Increasing
Reynolds number, the motion frequency of the jellyfish becomes slow due to the
reduced work done for the pulsations, and decreases and increases before and
after the mass density ratio of the jellyfish to the carried fluid is 0.1. The
total work increases rapidly at small mass density ratios and slowly increases
to a constant value at large mass density ratio. Moreover, as mass density ratio
increases, the maximum forward velocity significantly reduces in the contraction
stage, while the minimum forward velocity increases in the relaxation stage.</p>},
