Fluid flow with fluid pressure p(t, {\bf r}) are not changing in time:
p(t, {\bf r}) = p({\bf r}) |
This immediately leads to the stationary fluid velocity {\bf u}(t, {\bf r}) :
(1) | {\bf u}(t, {\bf r}) = {\bf u}({\bf r}) |
The fluid temperature T(t, {\bf r}) is supposed to vary slowly enough to provide quasistatic equilibrium.
This flow regime is often observed in pipeline fluid flow and reservoir fluid flows
