This is a collection of Python modules for routine CFD calculation but also as a sandbox for more complicated calculations.

• Colebrook-White friction factor check with single phase pipe
• Calculation of turbulence intensities for inlet BC specification
• Wheeler and PD moment inversion algorithms
• Method of classes method

Simple pressure drop calculation based on Colebrook-White. Tested with efunda calculator.

Also known as Modified Chebyshev algorithm (Gautschi 2004). Obtains a set of weights and abcissas from the set of moments.

Checks whether Hadamard matrices have non-negative determinants
