Summary

The Multi-Zone Combustion Model (MCM) is a software tool that enables computationally efficient and accurate prediction of combustion processes in internal combustion engines. MCM works with computational fluid dynamics (CFD) and detailed chemical kinetics (DCK) software packages to simulate internal combustion engine processes. Chemical kinetics simulation is critical to accurately predicting ignition adn emissions formation, but this type of simulation is also computationally intensive. MCM reduces the number of chemical reactors that must be calculated in an engine simulation from hundreds of thousands or millions to a few hundred calculations per time step. By reducing the computational cost of engine simulation, MCM has made it practical to do combustion simulations with reasonable run-times (hours to days instead of weeks to months) on smaller-scale computer systems without compromising accuracy.

Convergent Science, Inc. (CSI), formerly Convergent Thinking, LLC, is a world leader in Computational Fluid Dynamics (CFD) software. CFD software simulates the three-dimensional flow of fuel, air, and combustion products within an internal combustion engine. The staff at CSI are experts in CFD simulations, numerical methods, model development, and design optimization. Since 1997, Convergent Science has been providing quality consulting to the internal combustion engine industry and beyond.
