The ignition of gases by impulsive electrical discharge

Abstract

property does entail a corresponding disadvantage. I t implies a lack of sensitiveness, which is geometrically obvious, in the method when the relative course lies fairly near the critical course. W hether this would give rise to false alarms which might tend to discredit the method, is a question which must be decided by practical experience.

Injection and Combustion of Liquid Fuels

“…A still further increase in the air velocity causes the flattening action of the horizontal part of the twisted ribbon, and thus forms a cobweb-like film, which is so thin that it tears itself apart and diffuses into microdroplets as shown in (5) and (6). Increase of the air velocity gradually increases the number of films, at the same time making them smaller, and filmwise atomization occurs as shown by (7) and (8).…”

“…It is noted that, given the values of the physical variables and the number of ligaments Z for a given experiment, the values of k and of n can be determined readily by the method of least squares. -V r fP_lL±\ m (2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20) Recalling that 6 « D/Z, substitution of Equation (2 …”

“…By assuming that ^ is determined by the geometry of the chamber, the flow rate Q is a maximum for ^ W (3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13) which hence gives the criterion for optimum performance.…”

“…The total flow rate Q caji be written as [3][4][5][6][7][8][9][10][11][12] where K is the discharge coefficient. By assuming that ^ is determined by the geometry of the chamber, the flow rate Q is a maximum for ^ W (3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13) which hence gives the criterion for optimum performance.…”
