Heat Generation and Transfer in Electric Heating of a Laminar Flow of Food

Abstract

Electric heating allows even heating of food mixtures. Food flows including mixtures are often characterised in terms of laminar flows of Newtonian or power-law fluids. A model for the electrical heating of such flows has been developed. High temperatures are possible near the walls of the heater where food is slowest-moving; however, simulations of power-law flows where the viscosity is temperature dependent suggests that the region of high temperature is small.
