Resistive heating, also known as Joule heating, occurs when an electric current passes through a conductive material, generating heat due to the material's electrical resistance. While resistive heaters are simple in principle, their behavior can be highly nonlinear, influenced by temperature-dependent material properties, structural deformation, and thermal expansion.

Veryst offers expert modeling and simulation of resistive heating systems, optimizing electromagnetic, thermal, and structural performance.  Our work includes:

• Designing and optimizing heating elements such as calrods, busbars, and cartridge heaters
• Analyzing material behavior under extreme temperatures
• Addressing mechanical stress induced by thermal expansion.

Induction Heating

Induction heating is a highly efficient method for non-contact heating of conductive materials. A time-varying magnetic field induces eddy currents within the material, generating heat due to electrical resistance. This process is fast, precise, and energy-efficient, making it ideal for industrial and medical applications.

Veryst Engineering has extensive experience designing and optimizing coils to maximize heating efficiency, thermal management strategies for optimal process performance, and multiphysics simulation to incorporate coupled electromagnetic, thermal, fluid flow, and structural physics.

Example Applications:

• Inductively heated catalytic processes for chemical and energy applications
• Selective hardening of metal components in automotive and aerospace industries
• Eddy-thermography simulation for development of non-destructive testing techniques for aerospace parts.

Dielectric (RF & Microwave) Heating

Dielectric heating (RF and Microwave) excites dipolar molecules such as water, polymers, or biological tissues using radio frequency (RF) or microwave energy, leading to rapid and uniform heating. This method is widely used in industrial, medical, and food processing applications.

Veryst Engineering has broad experience in:

• RF Ablation device modeling for medical applications
• Dielectric heating optimization in process heating systems
• Microwave chamber design for uniform energy distribution.
