Imposed constraints assured a minimum pressure rise and non-stalled flow conditions across the blades.
Oesophageal manometry was carried out, after the patients had fasted overnight, using a low-compliance perfusion system with a pneumohydraulic perfusion pump (Mui Scientific, Mississauga, Ontario, Canada), with a minimum pressure rise rate of 300 mmHg/s and a standard four-channel manometric catheter with the manometric ports spaced 5 cm apart.
Experimentation was conducted by following standardized test procedures and using standardized apparatus for determination of maximum explosion pressure, size-normalized maximum rate of pressure rise, minimum explosible concentration, minimum ignition energy, and minimum ignition temperature.
The explosibility parameters investigated for both flocculent materials include maximum explosion pressure (Pmax), size-normalized maximum rate of pressure rise (KSt), minimum explosible concentration (MEC), minimum ignition energy (MIE) and minimum ignition temperature (MIT).
In this study the Minimum Explosion Concentration (MEC), Over Pressure Rise (OPR), deflagration index for gas and dust hybrid mixtures (Kst) and explosive region of hybrid fuel mixtures present in Ventilation Air Methane (VAM) were investigated.
The explosibility parameters investigated for both size ranges of titanium include explosion severity (maximum explosion pressure (Pmax) and size-normalized maximum rate of pressure rise (KSt)) and explosion likelihood (minimum explosible concentration (MEC), minimum ignition energy (MIE) and minimum ignition temperature (MIT)).
The explosion parameters minimum explosible concentration (MEC), rate of pressure rise (dP/dt), deflagration index (Kst), peak to initial pressure rise (Pm/Pi), turbulent and laminar flame speeds were determined using a calibrated hemispherical disperser in the 1 m3 vessel.
Properties measured at the lab scale include: the flammability limits; auto-ignition temperature; minimum ignition energy; peak constant-volume pressure rise; deflagration index; and laminar burning velocity as a function of equivalence ratio.
The measured parameters include maximum deflagration pressure rise, maximum rate of pressure rise, minimum ignition temperature, minimum ignition energy and minimum explosible concentration.
Maximum explosion pressure (Pmax), maximum rate of pressure rise (dP/dt)max, and minimum explosion concentration (MEC) were tested in the spherical chamber.
The authors predict that the challenge of future research on design of two-phase ejector is how to generate a pressure rise in diffuser for minimum compressor work and optimum COP improvement.
