Inline Induction Heater
Application ID: 35541
Ferritic stainless steels have become more and more popular in the food industry because of their relatively low and stable price and due to the absence of nickel in their components. Their resistance to corrosion can be improved by adding chromium or molybdenum, and their magnetic properties offer new techniques in food processing.
The new Inline Induction Heater application computes the efficiency of a magnetic induction apparatus for heating liquid food that flows in a set of ferritic stainless steel pipes. A circular electromagnetic coil is wound around a set of pipes in whichliquid food flows and is heated. A magnetic field, resulting from current passing through the coil, generates eddy currents, which are responsible for the inductive heating. Finally, heat is transferred to the fluid, essentially by conduction.
With this app, you can investigate various sets of pipe configurations by changing their number, length, thickness, and material. You can also tune the coil by setting the number of turns, wires radius, current density, or excitation frequency. In order to optimize the design, the application reports the overall maximum temperature of the fluid, minimum temperature at the outlet, the average temperature elevation at the outlet, and the thermal efficiency of the heater.
This application example illustrates applications of this type that would nominally be built using the following products:
however, additional products may be required to completely define and model it. Furthermore, this example may also be defined and modeled using components from the following product combinations:
The combination of COMSOL® products required to model your application depends on several factors and may include boundary conditions, material properties, physics interfaces, and part libraries. Particular functionality may be common to several products. To determine the right combination of products for your modeling needs, review the Grille de Spécifications and make use of a free evaluation license. The COMSOL Sales and Support teams are available for answering any questions you may have regarding this.
