Heat Transfer

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.

Reagent Dry-Down in a Microwell

Manufacturing medical diagnostic kits involves drying reagents to be reconstituted later, during use. For this project, Veryst simulated reagent dry-down of a small volume of liquid in a microwell to investigate the effect of process parameters including oven temperature and humidity.

Safe Distance? A Simulation of the Trajectory of Exhaled Droplets

Understanding the movement and behavior of droplets a person emits by breathing is essential for infectious disease control. Veryst modeled the trajectory of particles from an individual running at a moderate pace with another runner in their slipstream, while both are exhaling without wearing a mask.

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

Microfluidics

Veryst offers a comprehensive approach to solving problems in microfluidic device development.  We employ an array of modeling tools, such as scaling arguments, analytical formulas, computational simulations, and laboratory testing to inform the design and integration of common components.

Multiphysics Modeling

Accurate simulation of many products now requires a multiphysics approach. Veryst Engineering specializes in multiphysics problems involving solids, fluids, heat transfer, mass transfer, acoustics, and electromagnetics. Our modeling and analysis expertise includes fluid-structure interaction, thermal-structure interaction, structural-acoustic vibrations, conjugate heat transfer, Joule heating, and microwave heating.

Non-isothermal Flows

Modeling convective flow requires coupling fluid-flow with heat transfer.  The coupled processes can be very complex, particularly if the fluid flow is turbulent, or if the heat transfer involves processes such as boiling, evaporation, or mixed fluids with varying thermal properties.  F

Thermal Analysis

Veryst offers clients consulting services in thermal modeling of both solid and fluid systems, including interactions between these systems. We employ state-of-the-art finite element analysis and computational fluid dynamics methods both to analyze and visualize the thermal profiles within client systems. Our simulation capabilities also include hard-to-solve coupled problems, including the interactions between thermal and structural effects and fluid movements resulting from thermal gradients.

Article in NASA Software Tech Briefs

Veryst Engineering published an article in the September 2013 issue of NASA Software Tech Briefs titled "Conjugate Thermal Analysis of a Generic LED Light Bulb."  The article illustrates how a coupled thermal CFD (computational fluid dynamics) analysis is used to predict the temperature vari
