The purpose of this tutorial is to illustrate the use of user-dened scalars (UDS) and user dened memories (UDM) for modeling the electric resistance heating of fluids. Ohmic heating is also an advanced food processing method used to heat liquid foods, where electricity is passed through the liquid food itself. Through this process, the electrical energy is converted to heat energy. Conventional food processing heating methods can damage food quality due to the relatively slow energy transfer rate and signicant temperature gradients associated with conduction and convection driven heat transfer. In comparison, also, ohmic heating uniformly heats the entire mass, ensuring a product of better quality.
In this tutorial you will learn how to:
- UDS for modeling the electrical current continuity equation.
- UDM for storing the data at each cell center.
- Use the source terms to model the volumetric heating.
- Setup the solver and perform iterations.
- Check the convergence.
- Examine the results.
- Perform post-processing of UDS and UDM.
