Fluid flow momentum equation

WebSum of mass flow rates entering per unit time = Sum of mass flow rates leaving per unit time. The second conservation equation we have to consider in the control volume is the momentum formula. In the simplest form, the momentum formula can be represented by the following equation: –. WebThe momentum equation may be linearized similarly. Expanded eq. (5) becomes ρ0ut +ρ0uux +δρut +δρuux +px =(λ+2µ)uxx ( 10 ) Again, we can drop the higher order terms. The second, third, fourth terms are higher than first order, so we can neglect them. Then the conservation of momentum equation becomes ρ0ut +px =(λ+2µ)uxx ( 11 )
