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,
