Dear all,(adsbygoogle = window.adsbygoogle || []).push({});

Someone could help me to understand how is mathermatically expressed the amplitude of the velocity gradient?

For example if vector of velocity is V(Ux,Vy,Wz)

The amplitude of the velocity gradient is? :

grad(V)= d/dx(Ux) +d/dy(Uy) + d/dz(Uz)

Is it fine?

Thanks in advance,

Indira
