In this study the effect of fuel temperature and environmental pressure on hypergolic ignition delay of triglyme (triethylene glycol di-Me ether) with the addition of sodium borohydride and hydrogen peroxide was investigated. The research was conducted in a constant volume chamber using a drop-test method where the oxidizer drop was released into the fuel pool. The environmental pressure (absolute) was 0.1, 0.5, 1, 1.5 and 2 MPa; while the fuel temperature was 22, 40 and 60°C. The main advantage of this study is that the effects of pressure and temperature were not investigated sep. but the tests were done for full matrix conditions. This allowed the evaluation of the effect of fuel temperature at ambient and elevated pressures, and the effect of environmental pressure for ambient and elevated fuel temperatures, based on direct ignition delay measurements, a unique feature of this research. Addnl., the dispersion of the results was analyzed in terms of repeatability of droplet parameters i.e. Weber number, as well as the diameter and velocity sep., along with eccentricity. The results have shown a huge influence on the ignition delay of both the fuel temperature and the environmental pressure. It was noticed that the average values of the Weber number and the droplet eccentricity remained at a similar level for all measurement points. In the experiment, the researchers used many compounds, for example, 2,5,8,11-Tetraoxadodecane (cas: 112-49-2Recommanded Product: 2,5,8,11-Tetraoxadodecane).
2,5,8,11-Tetraoxadodecane (cas: 112-49-2) belongs to ethers. Of all the functional groups, ethers are the least reactive ones. Ether bonds are quite stable towards bases, oxidizing agents and reducing agents. But on the other hand, ethers undergo cleavage by reaction with acids. Ethyl ether is an excellent solvent for extractions and for a wide variety of chemical reactions. It is also used as a volatile starting fluid for diesel engines and gasoline engines in cold weather. Dimethyl ether is used as a spray propellant and refrigerant. Methyl t-butyl ether (MTBE) is a gasoline additive that boosts the octane number and reduces the amount of nitrogen-oxide pollutants in the exhaust. The ethers of ethylene glycol are used as solvents and plasticizers.Recommanded Product: 2,5,8,11-Tetraoxadodecane
