abstract={This paper presents a real-time interactive system for simulating and visualizing motor-driven fluid hydrodynamics. The framework integrates a torque-based motor model with Heightfield and Smoothed Particle Hydrodynamics (SPH) fluid simulations. Utilizing modern OpenGL and an ImGui-based control interface, the system achieves consistent real-time performance on a CPU-based laptop and effectively illustrates the differences between surface-only and volumetric fluid models. Quantitative evaluation on a consumer-grade laptop demonstrates real-time performance near 60 FPS for SPH simulations up to approximately 2,000 particles, and interactive rates (15¨C30 FPS) up to about 5,000 particles. These results validate the system¡¯s suitability for interactive visualization, education, and exploratory research under modest hardware constraints, while acknowledging limitations due to weakly compressible SPH, simplified boundary handling, and heuristic impeller¨Cfluid coupling.},
