Ohmic Heating is an Alternative Preservation Technique-A Review
Ohmic heating offers an alternating to conventional heating because it simultaneously heats both phases by internal energy generated through electrical energy. In this process heating rate depends upon the electrical conductivity and field strength. By this method a product undergoes a minimum structural damage, retain its nutritional value. This technique gives excellent processed quality prod...
متن کاملAsymptotic stability for a symmetric parabolic problem modeling Ohmic heating
We consider the asymptotic behavior of the solution of the non-local parabolic equation ut = (κ (u))rr + (κ (u))r r + f (u) (a+2πb ∫ 1 0 f (u)r dr) 2 , for 0 < r < 1, t > 0, with a homogeneous Dirichlet boundary condition. The equation is the so-called Ohmic-heating model, which comes from thermal electricity in this paper, u and f (u) represent the temperature of the conductor and the electric...
متن کاملElectrode and pH effects on electrochemical reactions during ohmic heating
Undesirable electrochemical phenomena at electrode|solution interfaces during ohmic heating can be avoided or effectively inhibited by choosing an appropriate electrode material. We attempted to understand the electrochemical behavior of four types of electrode materials: titanium, stainless steel, platinized-titanium, and graphite at pH 3.5, 5.0, and 6.5. The electrodes were examined comparati...
متن کاملThe role of Ohmic heating in dc magnetron sputtering
Sustaining a plasma in a magnetron discharge requires energization of the plasma electrons. In this work, Ohmic heating of electrons outside the cathode sheath is demonstrated to be typically of the same order as sheath energization, and a simple physical explanation is given. We propose a generalized Thornton equation that includes both sheath energization and Ohmic heating of electrons. The s...
متن کاملMixed Convective Visco-Elastic MHD Flow with Ohmic Heating
An analysis of mixed convective MHD visco-elastic flow with heat and mass transfer from a vertical plate in presence of ohmic heating and viscous dissipation has been presented. The governing equations of the momentum, thermal and concentration fields are solved by perturbation technique. Expressions for velocity, temperature, concentration profiles and non-dimensional skin-friction coefficient...
