In this paper,the propeller and aft turbine are holistically designed. The Vortex Lattice Method is applied in the propeller design while an in-house Matlab code based on the Modified Blade Element Momentum Theory(M-BEMT) is used for turbine performance evaluation. The turbine blade is design and optimized by a Genetic Algorithm(GA). An application case study is completed and a combined thruster solution put forward. The efficiency in open water is simulated on the basis of CFD.[Results]At the same advance coefficient,the efficiency of the combined thruster is about 4% higher than that of the original propeller,with a slight increase in absorbed power. By adjusting the rotational speed,the combined thruster has lower power consumption of around 3.43% feasibility of this new concept device is validated by comparison with that of the original propeller. recovery turbine;Blade Element Momentum Theory(BEMT);CFD; Genetic Algorithm(GA)
