In Chapter 5, we introduced the concepts of linear momentum and angular momentum. Based on their derivatives, we derived the general form ofNewton's Second Lawfor both 2D and 3D systems. By applyingNewton's Second Law, we are able to determine the accelerations of a dynamic system at the ...
"To linearize the given momentum equation, we assume that the perturbed variables ($\delta \rho$), ($\delta p$), ($\delta \mathbf{v}$), and ($\delta \mathbf{B}$) are small compared to their equilibrium values ($\rho_0$), ($p_0$), ($\mathbf{v}_0$), and ($\mathbf{B}...

But for our purposes, in linear algebra, we write the preceding equations as a vector equation that looks like this:Here, b is the result vector.Placing the point (3, 1) into the vector equation, we get the following:As we can see, the left-hand side is equal to the right-hand ...

(seeSect. 5.2). The first equation is that of conservation of linear momentum, the second one that of conservation of mass, which is also called the continuity equation. The term (u• ∇)udescribes the process of convective transport, while —div [v(∇u+ ∇uT)] the process of ...
