Incorporate momentum coefficient (β) #1

Closed RegMeasures closed 5 years ago

RegMeasures commented 5 years ago

So far none of my river hydraulics includes a momentum coefficient (β) (also termed Boussinesq coefficient) to correct for non-uniform velocity distribution. This should be fixed.

Interestingly it is possible to use the momentum coefficient to turn off the convective acceleration term of the momentum equation - interesting and potentially useful

Beta should probably be in the range 1.05 to 1.1 https://nptel.ac.in/courses/105106114/pdfs/Unit6/6_1.pdf
