This paper describes the basic principles and physical modelling of systems based on the ohmic heating of liquids by passage of mains frequency electric current through the liquid itself, in order to heat it on a continuous flow regime. Preliminary numerical results for non-Newtonian fluids of Herschel-Bulckley type (Carbopol 940) are presented and the effect of natural convection, and shear and temperature dependence are emphasized.
