Cabin Bioaerosol Control: HEPA Loop & Concentration Curve (2D)

2D side-view companion to the 3D HEPA recirculation-loop simulator: watch spacecraft cabin bioaerosol particles drift from crew source to filter while a live strip chart plots the well-mixed compartment ODE's exact exponential approach to steady state N(infinity), with pan/zoom on the duct view.

This 2D companion to the 3D HEPA recirculation-loop simulator strips the cabin down to a side-view duct with a live strip chart underneath, so the exact exponential relaxation curve the compartment ODE predicts is directly visible and measurable rather than only inferred from particle density. Crew members shed bioaerosols into a well-mixed cabin while the environmental control loop pulls air through a HEPA filter and recirculates it; adjust crew size, air-exchange rate, HEPA efficiency and cabin volume, or simulate a clogged filter, and watch both the particle stream and the N(t) curve respond in real time. Drag the duct view to pan and scroll to zoom in on the filter crossing.
