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 (15–30 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–fluid coupling.
