Abstract

The results of an experimental study of the relationship between the width of the turbulent combustion zone (TCZ) and the composition of the composite fuel (hythane), the maximum pressure in the combustion chamber of variable volume, and the propagation speed and electrical conductivity of the turbulent flame are presented. It was found that the width of the TCZ has a characteristic dependence on the composition of hythane. It was experimentally found that, despite the change in the coefficient of excess of air, the hydrogen concentration in the fuel, the turbulence intensity and type of fuel (hythane and gasoline), and the dependences of the TCZ width on the turbulent flame propagation velocity and on the electrical conductivity of the flame remain unchanged, as well as the dependence of the maximum pressure on the width of the TCZ. The results of the work can be used in the design and development of energy-efficient and low-emission combustion chambers.
