Question:
the rate of viscous dissipation is expressed as 2E : E where E is the rate of strain tensor, and : is the double-dot operator.
1. Calculate this quantity and express it in terms of the components of the velocity vector u = (u1, u2, u3). 2. Calculate the viscous dissipation rate. knowing a simple shear flow in 2D, u = kx1 e2
