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....
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....
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....
The automotive industry has been struggling to accurately predict the thermal performance of a vehicle’s exhaust system for the better part of 15 years. Due to the internal gas flow complexity inherent in a vehicle’s exhaust system, it has historically been one of the most difficult systems to model and predict — and among the most expensive due to the computational requirements....
With our newest software release comes one of the most powerful features to date, the addition of the Exhaust Tool. The Exhaust Tool will help you drive thermal management and heat protection for your most critical components, providing opportunities not only for cost-savings but also revealing new paths for product innovation....
