Python support for CFD

There's a number of calculations I often perform prior to a CFD calculation such as

  • Colebrook-White friction factor check with single phase pipe
  • Calculation of turbulence intensities for BC specification
  • Wheeler moment inversion algorithm

General

Pressure drop

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

Turbulence

Turbulent BC

Population balance modelling

Methods of moments

Wheeler's moment inversion

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

Realizability check

Checks whether Hadamard matrices have non-negative determinants
