Norsyamsul Syazwan Mohd Nuji Analysis of diesel spray characteristic at high pressure injection / Norsyamsul Syazwan Mohd Nuji Kuantan, Pahang : UMP, 2012 xiii, 42 p. : ill. (some col.) ; 30 cm. + 1 CD-ROM Project paper ( Bachelor of Mechanical Engineering Automotive) -- Universiti Malaysia Pahang - 2012 Bibliography : p. 40-41 In diesel combustion, spray evaporation and mixture formation during ignition delay period play an important role in ignition, combustion and emission production. Spray evaporation begins immediately after start of fuel injection under the condition of high ambient temperature, in particular, at the middle of the spray. Spray atomization is fast promoted at this region, leading to ignition. The ambient temperature and injection pressures affect the droplets size and the number of droplets. In this project, the fuel will be injected at various injection parameters inside spray chamber in order to study the affect of that parameter towards spray characteristics. An analysis study was performed to investigate the macroscopic spray structure and the spray characteristics of high-pressure injector for the diesel engine. The spray structure and microscopic characteristics of high-pressure diesel injector were investigated when fuel was injected at various injection pressures and different nozzle diameter. Spray developing process, spray cone angle and spray tip penetration were obtained by using the software simulation of ANSYS-FLUENT, and the quantitative result of spray characteristics will be analyzes.
