...D. P. Gardiner; G. Wang; M. F. Bardon; M. LaViolette; W. D. Allan It has been demonstrated by previous researchers that an approximate value of the bulk flow velocity through the spark plug gap of a running spark ignition engine may be deduced from the voltage and current wave forms of the spark...

... investigated at three port orientations. In-cylinder flows in orthogonal planes were measured using particle image velocimetry (PIV). The PIV data were processed to calculate the large-scale mean vorticity and mean high-pass filtered velocity. Combustion performance data were separately acquired at two load...

... is a typical design for 300/600 MW steam turbines currently in operation. Static pressure at the diffuser tip and hub endwalls and at the hood outer casing is measured and nonuniform circumferential distributions of static pressure are noticed. The velocity field at the model exit is measured and compared...
