What problem does it solve?

Cantera combustion simulations automate the computation of key combustion metrics like adiabatic flame temperature, ignition delay, and laminar flame speed so engineers can analyze and compare fuels and mechanisms without manual derivations.

Core Features & Use Cases

• Adiabatic flame temperature sweeps: calculate equilibrium product states across equivalence ratios to understand peak temperatures and composition trends for conditions like CH4/air and H2/air.
• Ignition delay estimation: simulate constant-volume homogeneous reactor behavior and determine ignition timing using an OH-based ignition criterion over a temperature range.
• Laminar flame speed calculation: run 1D freely propagating flame solutions with refinement criteria to obtain burning velocity versus equivalence ratio for engine and safety analysis.
• Advanced reactor analysis (PSR & sensitivity): evaluate perfectly stirred reactor residence-time behavior and support mechanism comparisons (e.g., GRI-3.0 vs custom mechanisms).

Quick Start

Use the cantera-combustion skill to compute ignition delay for methane at equivalence ratio 1.0 and a specified pressure, then return a table of ignition delay versus initial temperature.
