The invention discloses a model-scale ship bubble generation simulation device, method and system. The device comprises a dragging system, an air supply system, a flow regulation system, a test pool and a ship model. The simulation device simulates bubble cloud generation positions of a ship model under various working conditions through CFD software, generates a data set and inputs the data set at the front end of a computer, air outlet sieve plates with different depths in the ship length direction are installed on a ship bow, the control system controls the air conveying pressure and flow, and the air outlet sieve plates are arranged in the ship bow. The air outlet sieve plate can simulate bubble cloud generation conditions similar to actual ship navigation at different positions, and basic support is provided for simulating and researching the influence of bubble entrainment on the actual ship navigation under the model scale. The navigation speed of the ship model is adjusted through the dragging system, the flow adjusting system is controlled through the computer, corresponding bubble clouds in a data set are generated at different positions on the two sides of the ship model according to different working conditions, and the bubble entrainment process of actual navigation is simulated under the model scale.
