WebWhile designing combustion systems, flame speed plays an important role in determining their performance. In this module, you will learn how to calculate flame speeds. Note that this parameter depends upon the type of reaction mechanism that is being employed and the thermodynamic conditions in the combustion chamber. WebTypical flame speed results are summarized in the following plots. The cantera simulation results are shown on the left and openFoam results with the same mechanisms on the right. Cantera uses an adaptive meshing procedure, while the openFoam mesh varied between 50 and 25 micron resolution.
