equivalence ratio
Ignition delay time behind a reflected shock wave is measured for a lean propane-air mixture with an equivalence ratio of ? = 0.5 in wide temperature and pressure ranges (T = 880-1500 K, P = 2-500 atm).
      
Both experiment and numerical simulation were made at inlet temperature of 553 K, inlet velocity of 3 to 7 m/s and equivalence ratio of 0.3 to 0.5.
      
The combustion timing advances with the increase of DTBP concentrations, coolant temperature and equivalence ratio.
      
The chemical form of the nitrogen affixed to the PP surface is strongly dependent on the flame equivalence ratio.
      
With both models, the dependence of the results on the stoichiometric coefficient and the equivalence ratio can be expressed in an explicit manner.
      
Calculations performed for a range of values of the global equivalence ratio indicate how the flame evolves as a function of the chemical composition of the two streams.
      
These initial conditions are expected to depend mainly on four parameters: the equivalence ratio of the mixture, the amount of the initial energy deposition, the initial temperature and pressure of the mixture.
      
As forCH4/C4H10 mixed fuel, detonation velocities and detonation limits as a function of the equivalence ratio of the whole mixture of mixed fuel coincided with those ofCH4 single fuel.
      
Two types of gaseous mixtures are used: (i) a heavy gas (equivalence ratio : ); (ii) a light gas .
      
Prescribed parameters are the upstream values for the pressure, temperature, and Mach number, the fuel/air equivalence ratio, a hydrogen/methane ratio, and the detonation wave angle.
      
The numerical results show that the equivalence ratio $\Phi$ of the gas-mixture is high enough in order to have a non-reactive gas close to the wall which keeps constant the hydrogen temperature along the centre-body.
      
An experimental study of the detonation in gaseous nitromethane (NM) and nitromethane-oxygen mixtures has exhibited unambiguously the existence of a double cellular structure in the range of equivalence ratio $\phi$ from 1.3 to 1.75 (NM).
      
Experiments were primarily carried out with stoichiometric propane-air, however the affect of mixture reactivity was also investigated by varying the mixture equivalence ratio.
      
The detonability study, regarding nitrogen dilution and equivalence ratio, was investigated in a 50?mm-diameter, 2.5? m-long detonation tube.
      
The simulation and measurements of detonation parameters were performed for THDCPD-exo/air mixtures at various initial pressure (1 bar >amp;lt;?P0 >amp;lt; 3 bar) and equivalence ratio (0.8 >amp;lt;?Φ >amp;lt; 1.6) in a heated tube (T0 ~ 375?K).
      
The equivalence ratio (test/reference) for the pharmacokinetic characteristics AUCnormwas 1.03 (geometric mean; 0.95-1.11, 90% confidence interval) and Cmax,norm1.01 (0.94-1.08).
      
The flame was fixed with an equivalence ratio of 1.0, a Reynolds number of 2500 and a plate-to-nozzle distance of 5d, while the inclination angles chosen for investigation were 57°, 67°, 80° and 90°.
      
The effects of equivalence ratio (?) and oxygen percentage (γ) on the combustion and entropy generation rate are investigated for different ?s (from 0.5 to 1.0) and γs (from 10 to 30%).
      
The CH2 signal as a function of height above the burner surface in a premixed, laminar, methane/oxygen flame (5.6 Torr and fuel equivalence ratio ~1.05) is measured by laser-induced fluorescence (LIF) in the
      
Over a wide range of conditions - obtained by varying the equivalence ratio, temperature, N2 dilution, and pressure - the wide- and narrow-band fluorescence techniques compare well.
