NUMERICAL ANALYSIS FOR OPTIMAL LOCALIZATION OF GAS INLET IN A VENTURI MIXER

Abstract eng:
The research is devoted to numerical analysis for the optimal localization of gas inlet in a Venturi mixer. Performance of the gas engine depends heavily on the quality of mixing of air and fuel, and therefore homogeneity of the mixture. In addition, there must be a suitable, adapted to the current load of fuel, air ratio . Responsible for the fact, among others is the mixer located before entering the combustion chamber of the engine. Incorrect parameter value  can lead to unstable operation of the engine as well as higher emissions going beyond current environmental standards. The Air-Fuel Ratio (AFR) was calculated for an air-fuel mixture of lean combustion gas engine for 𝜆 = 1.6 where the stoichiometric AFR for methane 𝐶𝐻4 equals → 9.52
