Abstract

A method andanalysis was developed to quantify the amplitude of deterministic spray unsteadiness based on Phase Doppler Anemometry (PDA) or Laser Doppler Velocimetry (LDV). It is a technique for measuring the direction and speed of fluids and air. In the simplest form, the beam crosses two beams of collimated, monochromatic and coherent laser light in the flow of the fluid being measured. The main objective of this project is to study the existing of the on line size, velocity and concentration of droplets or bubbles suspended in bio ethanol and gasoline mixture. In this study, the test chamber has been fabricated to provide an optical access for laser penetration during spray injection process. The injection rate and patterns, which are dependent on the different proportion of bio ethanol E10, E85 and pure gasoline determine the atomization process. Furthermore, spray cone angle and penetration length was studied and analyzed for each substances utilization. The result shows the velocities distribution and sizes for every point of the spray patterns. The flow patterns varied for each substances that used during the engine testing, The results interpretation achieve can definitely outcome the best theory for the whole project based on comparison each of the test mixture samples. In conclusion, the aims of the study have been fulfilled. Finally, several recommendations have been made to improve the relevant study and future works,
