TL;DR: In this paper, the effects of molecular transport on turbulent flame propagation and structure are critically discussed and the results of relevant studies of perturbed laminar flames (unstable flames, flame balls, flames in vortex tubes) are reviewed.

TL;DR: In this paper, a simple method is described for finding the natural frequencies of a plate of any size, thickness, and material as long as its plan form is similar to one of the plates used in the experiments, or any other plate whose frequencies are known.
Abstract: Experimental results are obtained for the lowest six natural frequencies and the associated nodal lines of triangular plates of uniform thickness clamped on one edge. Two series of plates are examined. In one series, a delta-wing plan form of fixed span is maintained, and five plates are examined having aspect ratios ranging from 2 to 20. In the other series, a fixed span and a fixed root chord are maintained, and five plates are examined having mean chord-line sweepback angles ranging from 0 to 45°. Test results are presented by graphs and photographs. These results show that in the delta-wing plan form of fixed span, the frequency of each of the six modes increases as the aspect ratio increases—that is, as the root chord is made smaller. No such general property is exhibited by the plates in the sweepback series, except for the ' 'bending'' modes, where the frequencies decrease with increasing angle of sweepback. A simple method is described for finding the natural frequencies of a plate of any size, thickness, and material as long as its plan form is similar to one of the plates used in the experiments, or any other plate whose frequencies are known.

TL;DR: In this paper, the essential role of molecular diffusion in the structure and propagation of turbulent flames was demonstrated, and it was shown that mixtures whose concentrations are near or beyond the conventional flammability limits can be rendered to burn strongly in turbulence, provided the controlling molecular mass diffusivity of the mixture exceeds its thermal diffusivities.

TL;DR: In this article, the authors discuss the fundamentals of combustion relevant to the burning of natural gas and describe the stability of laminar diffusion flames and aerated flames, and the normal burning velocity is a useful combustion parameter characterizing the overall reaction rate.

Abstract: Naturliche feste Brennstoffe sind Steinkohle, Braunkohle, Torf, Holz und pflanzliche Abfallstoffe (wie z. B. Bagasse, Palmolkerne, Kakaoschalen, Lohe u. a. m.). Sie enthalten naturbedingt neben der brennbaren Substanz auch wechselnde Mengen an Ballastststoffen wie Asche (Minerale) und Wasser. Zu ihrer Kennzeichnung dienen:
die Kurzanalyse (Wasser, Asche, Fluchtige Bestandteile, s. S. 486),
die Elementaranalyse (s. S. 487),
die Verbrennungswarme, (oberer) Heizwert und der untere Heizwert (s. unter c)), technologische Kennzeichen wie der Blahgrad als Mas des Backvermogens, das Kokungsvermogen nach dem Dilatometerverfahren, die Festigkeit u. a. (s. S. 487),
das Ascheschmelzverhalten nach DIN 51730 (s. unter e)),
die Sortenbezeichnung oder Kornung (Korngrenzen), vgl. Zahlentafel 3.
