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.

    本发明公开了一种模型尺度的船舶气泡发生模拟装置、方法和系统,该装置包括拖曳系统、供气系统、流量调节系统、试验池和船舶模型。模拟装置通过CFD软件模拟船舶模型在各种工况下气泡云生成的位置,并生成数据集在计算机前端输入,通过在船艏安装沿船长方向和不同深度的出气筛板,由控制系统控制输气压力和流量,使出气筛板能够在不同位置处模拟出与船舶实际航行相似的气泡云发生情况,为在模型尺度下模拟和研究气泡夹带对船舶实际航行的影响提供基础支撑。本发明通过拖曳系统调节船舶模型的航行速度,并通过计算机控制流量调节系统,根据不同工况在船舶模型两侧不同位置处生成数据集中对应的气泡云,在模型尺度下模拟实际航行的气泡夹带过程。
