How do I simulate an LCOE estimate?

Open this page and use the live Cooling Fan Selection tool below — set your inputs and the simulation runs instantly in your browser using real numerics. No install, no account needed.

Yes. The simulation runs free in your browser. A one-time unlock or a Pro plan adds advanced parameters, saved presets, data import, and clean exports.

Can I use my own numbers?

Absolutely — every input is adjustable, and with data import you can drive an LCOE estimate from your own measurements.

Governing equation

\frac{\partial u}{\partial t} + (u \cdot \nabla) u = - \frac{\nabla p}{ρ} + 1.0 e - 7 \nabla^{2} u, \nabla \cdot u = 0

Reading this result: Near-zero viscosity: momentum barely dissipates, so vortices persist and the flow tips into turbulent, chaotic mixing.

Decibels are logarithmic, so loudness does not add the way you expect: two identical sources are only 3 dB louder than one, and ten are 10 dB. Meanwhile a point source drops 6 dB every time the distance doubles (the inverse-square law). Sustained exposure above 85 dB risks hearing damage.

Governing equation

L = 85.0 - 20 lo g_{10} (4) = 73.0 dB

Reading this result: A single source falls from 85 dB to 73 dB across 4 m — about 6 dB lost each time the distance doubles.

About this simulation

The full Cooling Fan Selection tool models an LCOE estimate with the same numerics engineers and scientists use — running entirely client-side. Change any parameter and the result updates in real time, so you can build intuition, check a design, or teach the concept without spreadsheets or installs.
