Research Paper (postgraduate) from the year 2019 in the subject Engineering - Chemical Engineering, , course: M.TECH, language: English, abstract: This work is an experimental study for the measurement of ignition delay characteristics of burning fuel sprays in cylindrical combustion chambers. It is carried out on hot air and high pressure. The objective of the study is to investigation the effect of hot air temperature and a well as high pressure on ignition delay of diesel fuel sprays. The effect of blending of n-Pentane with pure diesel was investigated. An experimental set up was design for this purpose with the emphasis on optical method for measurement of ignition delay at various pressures. The results presented here show that ignition delay of diesel fuel spray decreases with increase in the temperature and pressure of hot air. Results also show the effect of methyl group being more dominant at low ignition temperatures and that of alkyl group being more dominant at higher temperature. Blending of n-pentane with diesel fuel, increase its ignition delay at low ignition temperatures. However, as the concentration of blending fuel was increased beyond 30%, the ignition temperature increase. Ignition temperature for 40% pentane blends is much higher that the pure diesel.

Ignition delays for mixtures of ethane, n-butane, isobutane, hydrogen, or propane with oxygen and nitrogen were measured using a flow system with two experimental procedures. Delays were measured in the temperature ranges 571 to 733 degrees C for ethane, 444 to 715 degrees C for n-butane, 564 to 713 degrees C for isobutane, 594 to 652 degrees C for hydrogen, and 540 to 681 degrees C for propane. The effect of fuel concentration was measured for all fuels, and delays were inversely proportional to fuel concentration to the 0.6 to 1.7 power. The effect of oxygen concentration was measured for propane and the butanes, and, in general, delays decreased slightly with increasing oxygen concentration. However, at very low temperatures, for n-butane, the dependence on oxygen concentration increased. The two procedures gave different absolute values for the delays, but the trends were the same by either method. Fram the variation of delay with temperature at constsnt fuel and oxygen concentration, apparent activation energies were calculated.

Delays were measured in a small rocket motor using a single pair of impinging fuel and oxidizer streams at 70 deg, 32 deg, and -40 deg F with fuel containing 0, 10, 20, 30, and 40 vol-% heptane. The acid was adjusted to 1% H sub2 O, 0.5% NO sub2, and 98.5% HNO sub3. Hard starts and long, variable delays were obtained in the lowest (EtS)sub3 P concentration range. The delays were short and independent of concentration or temperature with 90 and 100% (EtS)sub3 P. The time of ignition was determined by photocell and chamber-pressure pickup methods; the values agreed within the precision of measurement. Precaution similar to those for PhNH sub2 or N sub2 H sub 4 are necessary in handling (EtS) sub3 P.

Approximate linear relations were obtained when the logarithm of ignition delay was plotted against the reciprocal of absolute temperature for furfuryl alcohol and white fuming nitric acid (16 percent water) in the small-scale rocket engine (approximately 50 lb thrust) and for mixed butyl mercaptans and white fuming nitric acid (2 percent water) in a modified open-cup apparatus. Zero-temperature coefficients of ignition delay were obtained for furfuryl alcohol and white fuming nitric acid (2 percent water) in both apparatus for the temperature ranges investigated.
