'~ ABSTRACT: Previous models of spark i~aition processes had the disadvantage of not
� allowing for the difference between effects of the hest transfer from the reaction
= zone to the fresh bras on the development of alz i~,mition center and on the actual flame;
propagation. In the present; study, a simple nu~del of spark igili lion is fornnil.atecl '
which does not have these shortcomings . A11 thermophysical parameters were assumed
to be constant, and the reaction was assumed to be of the rero order. The model,
based on Diracs delta function, was used to derive ~.u~ expression for tre minumum
energy required far ignition. A system of equations which can be solved on a computer'

SOURCE: Tnzhenerno-fi,zicheskiy zhurnal, v. 10, no. 4, 1966, 523-530
TOPIC TACrS: ignition, heat convl~~ction, therrnc~l analysis, gas ignition
ABSTRACT: The SYivets method (P+1. Ye. Shvets, PhIM, vyp, 3, 1g1~9) has been used to
analyze the ignition problem of a gas reacting to a heated plate when the reactive
gas is fixed and forced or natural convection takes place. The analytical conditions
of ignition were obtained. The ignition conditions for the gas and forced natural
convection agree with Well-known exact values (P. H. Thomas and P. ~;. Sower, Trans,
Fa`r. Loc~~, 57, 2007, 1961; Tau-i-Tung, Sb. "Voprosy zazhiganiya i stabilizatsii

ABSTRACT: Dor~dnitsyn's method of inte ral relationships (Dorodnitsyn A. A.
ZhP1~iTF, No. 3, 1960.} was used to so ve in first-order approximation the nonsteady
state system of e: uq ation,s for thermal explosian~/ Solutions were obtained far
igniition in an infinite cylinder with an arbitrary change of the w~~11. temperature
and for self-ignition of an incompressible reacting fluid flowingl~in an infinite
cylinder with allowance for friction.~~ The method can be also applied to other
ignition problems. Orig. aft. has: 32 formulas. (EV}
