“…The design of the present RCM is based on several other compression machines reported in the literature, such as those of Affleck and Thomas (1968), Beeley et al (1980aBeeley et al ( , 1980b, Park and Keck (1990), and Minetti et al (1994). As shown in Figure 1, the present RCM system consists of a driver piston, a reactor piston, a hydraulic motion control chamber, and a driving air tank.…”

“…With significant efforts involved, RCM has emerged as a powerful tool to study chemical kinetics at elevated pressures and temperatures (e.g., Griffiths et al, 1997;Minetti et al, 1996a;Tanaka et al, 2003a). A summary of the features of the existing RCMs employed by various research groups, including those at National University of Ireland (Affleck and Thomas, 1968;Brett et al, 2001;Gallagher et al, 2003;Silke et al, 2005;Wü rmel and Simmie, 2005), University of Leeds (Beeley et al, 1980a(Beeley et al, , 1980bClarkson et al, 2001;Griffiths et al, 1993bGriffiths et al, , 1997Griffiths and Whitaker, 2002), University of Science and Technology (Desgroux et al, 1995(Desgroux et al, , 1996Minetti et al, 1994Minetti et al, , 1995Minetti et al, , 1996aMinetti et al, , 1996bMinetti et al, , 1999Ribaucour et al, 2000), and Massachusetts Institute of Technology (Lee and Hochgreb, 1998;Park and Keck, 1990;Tanaka et al, 2003aTanaka et al, , 2003b, was recently reported by Donovan et al (2004). It is also noted that the rapid compression facility at University of Michigan is designed to achieve compression ratios in the range of 16 to 37 and pressures greater than 20 bar (Donovan et al, 2004).…”

“…Due to the effects of heat transfer on the pressure of the test gases, CR eff will naturally be lower than the physical compression ratio determined using Eqn (6). Using this effective compression ratio, the maximum gas temperature can be calculated and compared to the measured gas temperature as a check on the accuracy of the measurement and the validity of the assumption of an isentropic gas core region.…”

A free-piston rapid-compression facility (RCF) has been developed at the University of Michigan (UM) for use in studying high-temperature combustion phenomena, including gasphase combustion synthesis and homogeneous charge compression ignition systems. The facility is designed to rapidly compress a mixture of test gases in a nearly adiabatic process. A range of compression ratios, currently 16 to 37, can be obtained. The high temperatures and pressures generated by the RCF can be maintained for in excess of 50 ms, providing an order of magnitude increase in observation time over what can be obtained using shock tubes. The facility is instrumented for temperature and pressure measurements as well as optical access for use with laser and other optical diagnostics. This work describes the UM-RCF and its operation, establishes obtainable pressures and temperatures (over 1900 kPa and 970 K for predominately N 2 gas mixtures, and over 785 kPa and 2000 K for Ar gas mixtures), and demonstrates the repeatability of the UM-RCF experiments (< 3% run-to-run variability in peak pressure) for combustion studies. The experimental results for time histories of temperature and pressure are interpreted using analytical isentropic models. Comparison between the isentropic predictions and the experimental data indicate excellent agreement and support the conclusion that the core region of the test gases is nominally uniform and is compressed isentropically.2

“…Understanding the characteristics of the ignition and explosion of IPN/JP-10 in air aerosols is an important prerequisite for their proper usage. Although many research studies on the ignition and detonation of JP-10/air [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21] and IPN/air [22][23][24][25][26][27][28] have been conducted, only minimal information on the explosivity of IPN/air aerosols at different SMDs is available in the literature. Moreover, few researchers have focused on the explosivity of IPN and JP-10 binary mixtures or performed comparative studies of IPN/ JP-10 mixtures in air aerosols.…”

This article presents a comparison of the explosion characteristics of mixtures of isopropyl nitrate (IPN, (CH 3 ) 2 CHONO 2 ) and JP-10 (C 10 H 16 , tricycle [5.2.1.0 2,6 ] decane) in air aerosols. The explosion pressure, flame temperature, maximum rate of pressure rise, maximum rate of temperature rise, and lower flammability limits (LFLs) were measured for two sets of IPN and mixed IPN/JP-10 in air aerosols at different concentrations and Sauter mean diameters (SMDs) of 19 mm and 34 mm, respectively, and the values were compared with the experimental results of JP-10/air aerosols with SMDs of 20 mm and 35 mm (from our previous research). Experiments were also performed to study various concentrations at various ignition energies for the IPN/ air aerosols and the explosions of binary mixture aerosols with various mass ratios of IPN and JP-10. The experimental results indicated that for the IPN/air and JP-10/air aerosols with a mean SMD of~34 mm, the maximum peak pressure and maximum peak temperature of the IPN/air aerosols were greater than those of the JP-10/air aerosols. The maximum rate of pressure rise of the IPN/air aerosols reached a maximum value of 395.3 MPa/s at a mean SMD of~34 mm, and the pressure increased more abruptly in the IPN/air aerosols than in the JP-10/air aerosols. The LFLs of the IPN/air aerosols occurred with a total concentration of 197 g/m 3 at a mean SMD of 19 mm and a total concentration of 233 g/ m 3 at a mean SMD of 34 mm, whereas the LFLs for the JP-10/air aerosols with SMDs of 20 mm and 35 mm were less than 47 g/m 3 and 40 g/m 3 , respectively. The experimental results presented here also showed that the maximum peak pressure was 1.07 MPa at a binary liquid mass ratio of IPN:JP-10 (%) of 72 : 28 and a mean SMD of~34 mm.Keywords: IPN/air and JP-10/air aerosols · Explosion characteristics · Lower flammability limit · Ignition energy · Various mass ratios of binary mixtures 2 3 4 5 6 7 8
