摘要: The vortex flow behind a bluff body operating in ground effect was studied. equipped with an upswept aft section. With correctly modelled ground, the found to experience significant forces proximity ground. characteristics of these were associated complex turbulent wake/vortex system. Off-surface laser doppler anemometry (LDA) measurements identified position and strength vortex. cause initial reduction slope force vs. model height curve determined be breakdown.
