What is the Combustion Analyzer multi-solver?

Combustion Analyzer is a guided workflow that chains 2 individual PolySim solvers into one end-to-end analysis, piping each result into the next step.

Yes. Every step runs entirely in your browser using real numerics — no install, no account, no cloud cost. Custom or private solver packs are available as a paid service.

Controls

Set moles, temperature, and volume — pressure follows from PV = nRT. Compress the volume or heat the gas and watch the pressure climb.

LawPV = nRT

Governing equation

P V = n R T : 103.9 kPa \times 24 L = 1 mol \times 8.314 \times 300 K

Reading this result: At 300 K, 1 mol in 24 L, PV = nRT gives about 103.9 kPa (1.03 atm). Mean molecular speed scales with the square root of temperature, so this gas moves about 1.00x as fast as it would at 300 K. Around room temperature the molecules carry moderate kinetic energy. Expanding the volume spreads the molecules out, lowering the collision rate and the pressure.

molecular speeds in a gas

Controls

Gas molecules do not all move at one speed — they spread into this distribution. Heat the gas or lighten the molecule and the curve broadens and shifts faster.

Governing equation

f (v) = 4 π (\frac{m}{2 π k T})^{3/2} v^{2} e^{- m v^{2} /2 k T}, v_{p} = \frac{2 k T}{m} = 0 m/s at T = 300 K

Reading this result: The peak (v_mp 0 m/s) sits below the average and RMS speeds because the long high-speed tail pulls those means upward.
