A Study of the Genesis Mechanism of Unburned Hydrocarbons in a Constant Volume Bomb

The genesis mechanism of unburned hydrocarbons (HC) in a turbulent flow field has been studied by using constant volume cylindrical bombs. To investigate the influence of the turbulence intensity on combustion duration and HC, two different types of turbulence, one the turbulence generated by swirling flow and the other the isotropic turbulence, were selected. A special technique was devised to freeze a reaction at an arbitrary moment of combustion process.
