The demand for petroleum based fuel increases because of growing transportation industry. Besides petroleum fuels, there are alternative fuels, such as ethanol, biodiesel, propane and hydrogen. Alternative fuels need to be developed to meet high demands of fuel, to increase the efficiency and to make transportation more environmental friendly. This report is about fundamental study of alcohol sprays. The concept of alcohol sprays is not well understood and research on this topic needs to be done in order to gain more information and to make this information useful. This concept is applied in the combustion chamber. The purpose of this report is to represent an introduction about the project and state the problem along with the objectives and methodology used to solve the problem. The first chapter makes brief introduction to the project. The report continues with the second chapter, which is literature review. Then it is followed by methodology. Conclusion part summarizes the report content. The objective of the present research is to study characteristics of different fluid sprays which are mean velocities and droplet sizes. It also observes the break up structure of different types of different fluid sprays. The study focuses on two points, which are: characteristics of fluids and the observation of the structure of alcohol and measurement of spray angle at nozzle exit. Spray characteristics of four different fluids (methanol, ethanol, diesel and water) are analyzed by Laser Doppler Anemometry (LDA) and Phase Doppler Anemometry (PDA). Laser Doppler Anemometry (LDA) systems were used to measure droplet velocities of fluid sprays. Phase Doppler Anemometry (PDA) systems were used to measure the droplet sizes of fluid sprays. These results were compared with other fluids such as diesel, water and oil. All the results are analyzed to further understand the characteristics of four different fluid sprays. Digital camera was used in order to observe the structure of fluids and to measure the spray angles at nozzle exit. Spray angle variations were observed under different pressures for each fluid.
