Automotive Transient Thermal Modeling Seminar - Improving Fuel Economy



With the new fuel economy targets approved by lawmakers in the Unites States, there is a significant focus among car manufacturers to explore various fuel economy strategies to improve performance.

Many of these fuel saving strategies don’t necessarily easily work in combination so vehicle integrators must investigate the system interactions and trade-offs among each of them for successful design. This often involves devising active control and thermal management systems to ensure best performance. This is where a developed vehicle transient thermal model is very valuable for design studies.

During this seminar, presented with the Computational Sciences Experts Group (CSEG), model development and various possible design and operational evaluation studies are discussed in detail using Flowmaster software.
