Cerebrospinal Fluid Dynamics (2D): Channel Flow & Pressure-Volume Loop

Interactive 2D cerebrospinal fluid dynamics simulator: a genuinely computed planar-Poiseuille velocity field through the aqueduct of Sylvius, a live intracranial pressure-volume phase-plane trajectory against the analytic Monro-Kellie curve, and a scrolling ICP/volume strip chart, all driven by the same choroid-plexus production and Davson's-equation outflow model as the 3D twin.

This 2D cross-section of cerebrospinal fluid physiology computes a genuine planar-Poiseuille velocity field through the aqueduct of Sylvius — channel gap height derived from outflow resistance, particle speed read off the resulting parabolic profile — instead of animating particles at a fixed scalar speed along a 3D curve. A live pressure-volume phase-plane plot traces the intracranial-pressure state point against the analytic Monro-Kellie compliance curve as choroid-plexus production, outflow resistance and heart rate are adjusted, with a scrolling ICP/volume strip chart alongside for a bedside-monitor view of the same mass-balance model driving the 3D twin.

⚙ Under the hood

A 2D cerebrospinal fluid simulator computing a real planar-Poiseuille velocity field through the aqueduct of Sylvius (channel gap derived geometrically from outflow resistance, particle speed read off the parabolic profile each frame), alongside a live ICP-volume phase-plane trajectory against the analytic Monro-Kellie compliance curve and a scrolling bedside-monitor-style ICP/volume strip chart.
