Chemical kinetics and internal combustion capability for engine simulation

1st December 2015

Posted By Paul Boughton


Altair has announced that Lund Combustion Engineering – LOGE AB has joined the Altair Partner Alliance (APA), adding LOGEsoft and LOGEengine for chemical kinetics modelling and internal combustion engine simulation.

LOGEsoft performs combustion and chemical kinetics simulations for all reactive systems with a unique solver for complex chemical systems.

LOGEsoft features a transient one-dimensional model for integrated engine combustion as well as after-treatment simulation containing detailed chemistry which enables it to analyse and optimise entire powertrain systems.  LOGEsoft is also capable of predicting emission levels of soot, NOx, CO and unburned hydrocarbons. The software offers affordable computation times compared to computational fluid dynamics (CFD) analysis with the complement of detailed chemistry. LOGEengine contains an intelligent tool for automatic simulation tuning, which aims to take experimental data to a complete case when coupled with LOGEsoft in-cylinder combustion models. LOGEengine uses a genetic algorithm to identify the ideal dataset for compression ratio, initial temperature, fuel/air mass, EGR rate, wall temperature and pressure offset.

"LOGEsoft and LOGEengine are meant to bridge the gap between fundamentals in chemistry and applied engineering,” said Fabian Mauss, CEO at LOGE. “Our software helps engineers access the latest research in chemistry in combustion and chemical engineering, which is important information during the design process. We are thrilled to be partnering with Altair because we see many opportunities for complementarity that HyperWorks user will view as valuable solutions."
