Welcome to the next generation of peristaltic pump simulation! This interactive tool lets you explore the inner workings of a peristaltic pump with a level of realism rarely seen outside of a lab. Whether you're a student, engineer, or just curious, you can experiment with all the key parameters and see their effects in real time.
What Makes This Simulator Unique?
True-to-Life Tube Deformation: The flexible tube doesn't just compress—it deforms with smooth shoulders and visible bulging, just like real silicone or rubber tubing under a roller. Watch how the tube wall is displaced and rebounds as the rollers pass by.
Functional Inlet & Outlet: The blue rectangles and colored markers show exactly where fluid enters (bottom) and exits (top) the pump. These are dynamically aligned with the tube geometry and update as you change parameters.
Occlusion Control: Adjust how tightly the rollers squeeze the tube. 100% occlusion means a complete seal; lower values allow some fluid to slip past, reducing wear but also decreasing efficiency.
Back-Pressure Simulation: Add resistance at the outlet to see how real-world loads affect flow rate and pump performance. Higher back-pressure means lower flow and more stress on the system.
Tube Wear Visualization: Over time, the tube sections under the rollers will show visible wear. Use the Reset Wear button to simulate replacing the tube and restoring performance.
Fluid Selection: Choose from a variety of fluids (water, plasma, oil, syrup, etc.), each with its own viscosity and color. See how thicker fluids move more slowly and respond differently to pump settings.
Real-Time Flow Rate: The overlay displays both the calculated and measured flow rates, so you can compare theory with simulated "experiment" as you tweak the controls.
Demo Mode & Inactivity: If you step away, the simulator will automatically enter demo mode, cycling through different settings to showcase its features. Any meaningful user action (slider, button, keyboard) will stop the demo and return control to you.
Audio Sonification: Turn on the audio for an immersive soundscape featuring a continuous hum that rises in pitch and volume with pump speed, punctuated by rhythmic squish bursts each time a roller compresses the tube. This provides both steady feedback and dynamic audio cues about the pump's operation.
How to Use
Use the sliders to adjust pump speed, number of rollers, tube diameter, occlusion, and back-pressure.
Select a fluid type to see how viscosity affects flow.
Click Play to start or pause the simulation, or Play Demo to watch an automated tour.
Try changing parameters while the pump is running to see instant feedback.
Future Directions: Enhanced Audio Sonification
The current audio system provides a foundation for immersive feedback, but there's significant potential for more comprehensive sonification that maps multiple pump parameters to rich, multi-dimensional soundscapes. Here are some directions for future development:
Multi-Parameter Mapping: Beyond the current speed-linked frequency, incorporate additional sonic dimensions such as timbre, stereo panning, and harmonic content to represent tube diameter, occlusion percentage, back-pressure, and fluid viscosity simultaneously.
Roller-Specific Audio: Each roller could produce its own unique sound signature, with the number of rollers affecting the rhythm and complexity of the audio pattern - more rollers creating denser, more intricate sound textures.
Material-Inspired Sounds: Develop "jelly-like" squish and push sounds that dynamically change based on tube deformation, creating organic, tactile audio feedback that feels like you're actually handling the flexible tubing.
Fluid Dynamics Audio: Different fluid types could have characteristic sounds - water might produce clean, crisp tones while viscous syrup creates deeper, more resonant audio with longer decay times.
Performance-Based Audio: Incorporate efficiency metrics into the sonification, where optimal settings produce harmonious sounds while suboptimal configurations introduce dissonance or noise, providing immediate auditory feedback about pump performance.
3D Audio Spatialization: Use binaural audio techniques to position sounds in 3D space, with inlet/outlet locations and fluid flow direction creating a spatial audio experience that matches the visual simulation.
Tip: This simulator is designed for both education and experimentation. Try extreme settings, compare different fluids, or just watch the mesmerizing motion of the rollers and particles. Have fun exploring!
