Welcome to OpenSMOKE++


OpenSMOKE++ is a general framework developed by the CRECK Modeling Lab for numerical simulations of reacting systems with detailed kinetic mechanisms, including thousands of chemical species and reactions.

OpenSMOKE++ can handle simulations of ideal reactors, shock-tubes, rapid compression machines, 1D laminar flames and multidimensional reacting systems, and it provides useful numerical tools such as the sensitivity and rate of production analyses.

OpenSMOKE++ is distributed in three main packages.

OpenSMOKE++ Suite

Simulation of ideal reactors (batch, plug-flow, perfectly stirred reactors), shock-tubes, rapid compression machines, laminar 1D flames (freely propagating and burner stabilized flames, counter-flow diffusion flames)

logo rocket


Solvers for steady-state and unsteady reacting flows in arbitrarly complex multidimensional geometries with detailed kinetic mechanisms (based on OpenFOAM)

logo university


Automatic reduction of detailed kinetic mechansims to a skeletal level, to allow their use in large scale CFD simulations. DoctorSMOKE++ is currently under testing. We plan to release it in a few months.

News from OpenSMOKE++

New paper on combustion of isolated fuel droplets

OpenSMOKE++ was used for simulating the evaporation and combustion of isolated fuel droplets. The work is a collaboration between the CRECK Modeling Lab, Cornell University, University of San Diego California and NASA Glenn Research Center. The main results have been published on Combustion Theory and Modelling in a paper with title: "The role of composition in the combustion of n-heptane/iso-butanol mixtures: experiments and detailed modelling".

40th International Symposium on Combustion in Milan in July 2024

Great News! The 40th International Symposium on Combustion will take place in Milano in July 2024. It is a real honor for CRECK Modeling Lab and OpenSMOKE++ members to be part of the organizing committee of the world most important event in the field of combustion!
