摘要	In this work, we investigate the wake characteristics of an underwater vehicle (i.e., the DARPA Suboff submarine model) using large-eddy simulation with the hull and appendages represented by the curvilinear immersed boundary method, and the propeller parameterized using an actuator disk (AD) model. Two cases with and without the AD propeller are carried out. The results show that the near wake for the case with the AD propeller is featured by an inner velocity-deficit region mainly due to the hull, a jet from the propeller, and an outer velocity-deficit region mainly caused by the fins and the sail. In the far wake, the interaction between the propeller's jet and the sail's wake dominates the upper region. As for the turbulence statistics, the peak magnitudes and positions of the Reynolds stresses and the levels of the power spectral density at certain frequencies are affected by the AD propeller in different ways at different downstream locations.
