Viscous dissipation Calculator

Viscous dissipation refers to the conversion of mechanical energy into heat due to the internal friction within a fluid. The formula for calculating viscous dissipation in a fluid flow system can be expressed as

Where:

• $\mu$ is the dynamic viscosity of the fluid.
• $\mathbf{v}$ is the velocity vector field of the fluid.
• $\nabla \cdot \mathbf{v}$ is the divergence of the velocity vector field, representing the rate of change of velocity.
