DR MURPHY ODE — Cryogenic Pump Cycle Simulator

Interactive dashboard for cryogenic reciprocating pump analysis using ODE-reformulated engines.

Engines

Engine	Speed	Fluids	Method
njit_10var	~1s/cycle	H2 only	Numba-JIT Euler loop, 10-variable ODE
ode_v2	~25s/cycle	H2 + N2	scipy ODE + Numba/CoolProp dual-backend
fast	~3s/cycle	H2 + N2	Production hand-rolled engine

Tabs

1. Simulation -- Full 42-parameter single-run with diagnostics, animation, and kWh tracking
2. Parameter Sweep -- 1D/2D sweeps with sensitivity analysis and Pareto frontiers
3. Compare Runs -- Save and diff up to 10 simulation runs
4. Real Pump Cycles -- Overlay real sensor data from TimescaleDB (requires DB access)

Physics

Simulates ICV/DCV valve dynamics, chamber thermodynamics, and mass flow through a simplex LH2/LN2 cryogenic pump at up to 1200 barg discharge pressure.

Built by Clear Skies Hydrogen (CSH2).
