Available in PDF, EPUB and Kindle. Book excerpt: An experimental visualization study of spray and combustion processes under simulated high-power-density diesel (HPD) combustion conditions is carried out. The scope of work includes characterization of high-pressure injection on test rig, macroscopic and microscopic characterization of non-evaporative sprays in atmosphere ambient condition or in pressurized chamber, and direct visualization of spray and combustion processes inside a single-cylinder optically accessible research engine. The results provide very interesting and dynamic information on spray structure, showing spray angle variations, primary breakup processes, and spray asymmetry under different combinations of injection systems and nozzle geometry. The injection systems tested included electronic unit injector (EUI), hydraulic unit injector (HEUI), and high-pressure common rail (HPCR) with both valve-covered orifice (VCO) and mini-sac nozzles. The near-field spray behavior is shown to strongly depend on the nozzle geometry, needle lift dynamics, and injection pressure, which is a function of the injection system. Some complementary numerical simulations using new transient schemes (space-time method) and primary breakup models (turbulent and cavitational) to better correlate spray and injector design are also discussed. Combustion visualization inside an optically accessible diesel engine equipped with HEUI injection system capable of both single and multi-stage injections was also successfully conducted. Nozzle hole flow area, injection pressure, and length of rate-shaping pipe are the dominating parameters that control the injection rate. The results showed that ignition delay and heat release of pre-mixed combustion is significantly reduced with increase of charge air density and temperature, and with pilot injection.

This book was released on 2021 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract : The spray impingement in diesel engines attracts the attention of engine researchers in recent decades as the physical size of the engine is reduced. Due to the spray impingement, the atomization, vaporizing and air-fuel mixing quality is altered compared to a free spray. For emission control, soot is one of the major particulate emissions from diesel combustion and its formation in an impinged spray is worthy to be investigated. Firstly, to understand the impinged spray characteristics, the experiments for both non-vaporizing and reacting conditions were conducted in a constant volume combustion vessel. The impinged spray was captured by a high-speed camera and the instantaneous spray propagation distance and rate were obtained. For a better understanding, the microscopic behavior of the spray propagation, the curvature of the impinged spray was calculated and a relationship between local fuel distribution and soot formation was found. After that, the apparent heat release rate from an impinge spray combustion and the heat flux through the impingement were analyzed. The apparent heat release rate was obtained by the internal chamber pressure and the heat flux was measured by heat flux probes embedded in the impinging plate. Then, the soot formation of an impinged spray was both studied from experiments and simulations. In the experiments, the natural luminosity mainly due to the incandescence of soot particles was captured by the high-speed camera. A computational fluid dynamics (CFD) approach was adopted to quantitatively study the soot formation in terms of absolute soot mass and soot mass fractions in the vicinity of the wall. In the last, the film formation under different ambient temperatures, impinging distances, and oxygen concentration was investigated in terms of film area and thickness. The impact of film formation on the soot outcomes was then investigated by comparing the rate of film vaporization and soot formation. To summarize, the main goal of this dissertation is going to benefit the understanding of the impinged spray in reacting diesel-relevant engine conditions. From experiments, a global view of soot formation in an impinged spray was analyzed and the mechanism of soot formation was further revealed by the CFD simulations.

Download or read book Analysis of Diesel Spray Characteristic at High Pressure Injection written by Norsyamsul Syazwan Mohd Nuji and published by . This book was released on 2012 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
