NS with variable body force-Momentum conserved?
In a fluid momentum equation with variable body force term, say
d(rhoU)/dt+ Del(rhoUU)=-gradP + del (mu)delU + F(alpha)
My viscosity mu = function of variable alpha and i have a body force F = F(alpha).
and as far as alpha,
I solve a scalar equation for alpha (something like a species) following U eqn.
is the fluid momentum conserved in this scenario?
