Theoretical principles of formation of homogeneous fuel mixtures in diesels

The article discusses molecular changes in the working mixture based on the composition of the biofuel blend. Theoretical calculations on the variations in heat release rates and fuel particle velocities reveal differing increases in heat utilization efficiency across various flow sections during atomization at different time intervals. The movement conditions of particles within the combustion chamber vary, particularly in fuels with multicomponent mixtures. Notably, a significant number of droplets (up to 20 million) of varying sizes are observed. Under these circumstances, abrupt spraying speeds are not recommended as they lead to fuel accumulation around the burner, hindering the combustion process. Furthermore, the article introduces analytical relationships aimed at promoting turbulence in flows of diverse fuels within the combustion chamber through the intensive mixing and throttling of fuel mixtures with varying compositions.
