The invention belongs to the technical field of propeller surface cavitation area evaluation, and particularly relates to a propeller surface cavitation area evaluation method and system under an oblique flow working condition. According to the method, on the basis of key parameters of a propeller, numerical simulation is carried out on the cavitation performance of the propeller surface under the oblique flow working condition by adopting a grid division and encryption method and a numerical simulation method, and the area of the surface cavitation is evaluated by adopting a specific calculation method. The system comprises a key parameter acquisition module, a mesh generation module, a boundary processing module, a model establishment module and a propeller surface cavitation area evaluation module which are connected in sequence. The method can quickly and accurately forecast the cavitation area of the propeller surface under the oblique flow condition.
