Time-of-flight test bench for the determination of speed ability of atomized fuel

Altai State Univeristy has developed a time-of-flight test bench that measures the optical density of fuel flow developing through two sections arranged in series. Passing through the flow, the light intensity changes according to the flow density and the signal from the photodiode intensifies and is converted to digital form, which is analyzed by a computer. The relative mass of the fuel flow having passed through the chosen optical section can be calculated, and the mass can be compared and normalized, and the time of delay of the fuel mass transport from the first up to the second section can be determined. By determining the speed of the fuel movement, it is possible to forecast the location of the main area of fuel flow at the characteristic moment of the fuel ignition and burning that determines the process of burning and cracking.
