4 Methods for Muffler Modeling

A Brief Overview of Exhaust Simulation A proper model of your exhaust system provides a critical boundary condition for your underhood/underbody thermal management. Many different simulation methods are chosen today based on the level of fidelity that is required and the boundary conditions that are available. There are four widely recognized methods for simulating exhaust systems....

The Importance of Transient Simulation for Underhood & Underbody Packaging

Packaging constrictions in new vehicles dominate the positioning and organization of components within the engine compartment. With less space and more temperature sensitive components, (plastics for lightweighting, infotainment, and electrical components) thermal management becomes an increasingly critical aspect of vehicle design. Component hot spots can lead to safety, durability, and warranty issues. Careful consideration of component placement and heat shields is mandatory to avoid costly late-stage fixes....

Advantages of Simulating Thermal Behavior of Underbody Components

Understanding the thermal behavior of underbody components can help an engineer balance the priorities and tightening restrictions for vehicle design. The underbody of a vehicle experiences some of the most thermally dramatic scenarios for which there is no simple solution. By using a method that provides accurate thermal predictions, engineers can assess a variety of design options early in the product development cycle. These predictions will provide a better understanding of the thermal behavior the vehicle will undergo under both extreme and common scenarios....

Why Thermal Sensation & Comfort Are Vital to HVAC Design

It's a hot August day. You're in the car on the way to a wedding. You have the air conditioning blasting. But as the sun beats down through the windshield, sweat collects on your spine as you lean into the seat....

Solving for both Human Comfort and Energy Efficiency

As the automotive industry continues to increasingly emphasize user-centered design philosophies, the wants, needs, and comfort of the actual humans inside the vehicle are afforded greater and greater attention. Of course, migration to user-centered design methodologies do not happen overnight, but by and large the trend lines are encouraging....
