VIRTUAL SIMULATION OF PMM TESTS INDEPENDENT OF TEST PARAMETERS

VIRTUAL SIMULATION OF PMM TESTS INDEPENDENT OF TEST PARAMETERS

The dynamic planar motion mechanism (PMM) tests are simulated numerically using computational fluid dynamics for a prolate spheroid underwater vehicle (PSUV) to find the effects of test parameters: the amplitude, frequency and flow velocity, and make the simulation independent of them.An amplitude of the Neff N90 C18FT56N1B Steam Oven sinusoidal pa

Joint towed streamer and ocean-bottom-seismometer data multi-parameter full waveform inversion in acoustic-elastic coupled media

Short-offset towed streamer data, and sparse ocean-bottom seismometer (OBS) data are not conducive to applying multi-parameter full waveform inversion (FWI) in production.It is challenging to reconstruct deep velocity in the former, and the latter suffers from severe acquisition footprints.We developed a joint acoustic-elastic coupled full waveform
