摘要：

Fuel laminar burning velocity is an important parameter in internal combustion engine modeling and combustion analysis. The present- paper deals with the development of a mathematical correlation able to provide laminar burning velocity for fuels/air mixture at different thermodynamic conditions. Therefore, a mathematical investigation of laminar burning velocity for most significant and used fuels was carried out. Fifth order logarithmic polynomial. functions were implemented to predict the propagating laminar burning velocity of combusting fuels as a. fiinction of equivalent ratio at different conditions of temperature and pressure. On the basis of results obtained, the mathematical model proposed in this paper showed a higher precision in experimental data fitting and the possibility to interpolate and use a single mathematical function for a wider operation field.
