\frac{D {\bf u}}{Dt} = \frac{1}{\rho} \nabla {\bf \sigma} + {\bf g} |
where
time and spatial variables | |
velocity of Continuum Body | |
density of Continuum Body | |
stress tensor of Continuum Body | |
sum of all body forces exerted on Continuum Body | |
Material derivative of the Continuum Body motion |
In Fluid Mechanics it takes form:
\frac{\partial {\bf u}}{\partial t} + {\bf u} \nabla {\bf u} = \frac{1}{\rho} \nabla {\sigma} + {\bf g} |
