Multiphysics Modeling of Joule, Induction, and RF Heating

In this webinar, we will review common modes of electromagnetic heating, their underlying physics, and key methods for developing accurate Multiphysics models. We will present three case studies of Multiphysics models that couple electromagnetics, heat transfer, and other physics, such as fluid flow and chemical reactions.

Calrod Thermal Analysis

How fast does a Calrod heat up and how high are the stresses during heating? To answer these questions, Veryst Engineering developed a coupled electric-thermal-structural multiphysics model of the Calrod, accounting for conduction, convection, and radiation.

CFD Modeling for a Hospital Room Ventilation System

Efficient ventilation can reduce a building’s energy consumption and minimize airborne pathogen transmission in hospital rooms.  Veryst used computational fluid dynamics (CFD) to simulate ventilation in a hospital room as well as the dispersion of particles and droplets.

Design and Simulation of a Catheter-Based Acoustic Ablation Device

Thermal ablation is a minimally invasive way to treat tumors, and simulating the physics of ablation can help in the design of ablation devices. Veryst designed and simulated a catheter-based acoustic ablation device relying on acoustic pressure waves to heat tissue to induce necrosis.

Infant Incubator Thermal Modeling

The main environmental factor affecting a premature neonate is thermo-neutrality, as the baby is incapable of regulating and maintaining his/her body temperature at a constant level. Veryst developed a computational model of heat transfer inside an infant incubator to optimize its design.

LED Light Bulb Heat Transfer Simulation

Both the efficiency and life of an LED bulb drop when operated at high temperature. Given the wide range of possible shapes and sizes of heat sinks, Veryst Engineering developed a rapid and effective tool to compare design alternatives and estimate LED temperatures.

RF Tissue Ablation Simulation

Radio frequency tissue ablation is a commonly used and minimally invasive tissue treatment procedure. Accurately modeling this kind of coupled multiphysics problem is often challenging. Veryst developed a COMSOL Multiphysics model accounting for heat transfer, electric field, and fluid flow to study the RF tissue ablation problem where an electrode is targeting a tissue close to a blood vessel.

Simulation of Heat Transfer From Impinging Turbulent Jets

Arrays of impinging fluid jets are an effective design solution for applications requiring large heat transfer rates. This case study demonstrates the ability of computational fluid dynamics (CFD) to predict heat transfer coefficient distributions and guide design choices to improve cooling uniformity.

Thermal Management in Battery Packs

Thermal management is crucially important for battery performance in consumer products, electric vehicles, and grid-level storage systems. In this case study, Veryst used multiphysics simulations to evaluate different thermal management strategies in prismatic and cylindrical battery packs.

Underfill Adhesive Flow and Cure

The microelectronics packaging industry relies heavily on adhesive bonding to assemble electronic components. Veryst built a COMSOL Multiphysics model of a thermocompression bonding process to help reduce bonding cycle time by simultaneously optimizing material and process variables.

Wear in Automotive Disk Brakes

When would an automotive disc brake need to be replaced? The continuous frictional sliding between two deformable surfaces leads to wear accumulation and ultimately failure of the weakest component. However, wear modeling is not readily available in most finite element codes. Veryst developed a wear model in COMSOL Multiphysics using differential equations for the wear depth based on a modified version of Archard's law.

Adhesive Joints & Interfaces

Veryst assists clients with the selection of adhesive materials, development of bonding processes, and mechanical analysis of interfaces. We employ chemical characterization, mechanical testing, and advanced computational methods to design robust adhesively bonded structures and to understand delamination failures.

Chemical Reactors & Bioreactors

Chemical reactors and bioreactors involve many layers of physics, including fluid flow, heat transfer, chemical reactions, and porous media. A deep knowledge of the underlying physical phenomena is essential when scaling up reactors.

Computational Fluid Dynamics (CFD)

Veryst offers state-of-the-art consulting in the design and analysis of gaseous and fluid systems and products. We employ advanced CFD analysis to solve problems involving fluid mixing, multiphase flow, phase change, non-Newtonian fluids, and microfluidic effects.

Fluidic Mixing

Veryst has deep expertise in fluidic mixing processes, which we leverage for our clients across industries.  A fundamental aspect of mixing is the stretching and folding of the interface between initially separated substances.  This occurs in many forms a
