'~ 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' i ~~ ws, i~l.so derived for detcrmi.ning thc~ tr^rnF~c:T�~~turc~ t~ncl thc> r,~,t~c~entz�at~i.on in the ignition' center.

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.
