Fuel laminar flame speed is an important property in internal combustion engine modeling and combustion analysis. The aim of this paper is to develop a mathematical model able to provide laminar flame speed for any fuel at any reagent thermodynamic condition. Therefore a mathematical investigation of laminar burning velocity in some main fuels was carried out. Fifth order logarithmic polynomial functions were used to predict the propagating flame speed of several combusting fuels as hydrogen, methane, ethane, iso-octane, etc. at different temperature and pressure conditions. On the basis of results obtained, the mathematical model proposed in this paper showed a higher precision in experimental data interpolation (about 2 % error) and the possibility to interpolate and use a single function for a wider operation field.

Abstract
Fuel laminar flame speed is an important property in internal combustion engine modeling and combustion analysis. The aim of this paper is to develop a mathematical model able to provide laminar flame speed for any fuel at any reagent thermodynamic condition. Therefore a mathematical investigation of laminar burning velocity in some main fuels was carried out. Fifth order logarithmic polynomial functions were used to predict the propagating flame speed of several combusting fuels as hydrogen, methane, ethane, iso-octane, etc. at different temperature and pressure conditions. On the basis of results obtained, the mathematical model proposed in this paper showed a higher precision in experimental data interpolation (about 2 % error) and the possibility to interpolate and use a single function for a wider operation field.Pubblicazioni consigliate
