Summary:

The behavior of air-entrainment in a Diesel fuel spray was studied by analyzing the air movement around a free non-evaporated Diesel fuel spray in a pressurized vessel. To measure the air movement around the spray. The density difference in the air near the surface of spray was measured as a tracer of the moving air. This was accomplished heating a stainless steel (SUS) wire with large current. The movement of air caused by the air-entrainment into the spray was recorded by a high speed camera system. By analyzing the recorded air movement, the air-entrainment was obtained. The effects of nozzle hole diameter, injection velocity and ambient gas density on the air-entrainment behavior were investigated. Some discussions were added to help considering the complex phenomena of air-entrainment into a Diesel spray, based on comparing the averaged air/fuel ratio inside the spray with both values of measurement and predicted by momentum theory
