About this document

Viscous Dissipation Function Derivation by Rafael Dalmau is a document available to read on EtoBox.

This document derives the dissipation function, which represents the rate of thermal energy generation within a small parcel of viscous fluid due to viscosity. It shows that the loss of kinetic energy due to viscosity (δE) is divided into work done on surrounding fluid (δW) and internal heating (δH). The dissipation function is defined as the heating per unit volume (Φ = δH/δV) and is shown to be the product of the stress tensor Tij and the rate of strain (∂i vj ). This results in an expression for the diss
