TITLE: Experimental investigation into the conductivity of combustion

TEXT: The electrical conductivity of combustion products from a methane-
oxygen flame to which K2CO3 had been added under standard pressure
(760 mm Hg), %as studied with a view to using.the chemical reactions in
the flame as a source of power and in order to determine the conductivity
of potassium vapor diluted with combustion products. The partial
pressure p of the potassium-waa-'varied within the range 10 7 to 10-4 atm.
-The electrical conductivity was de .termined from the attenuation of radio
waves (,.9000 Mc/sec) passing through the flame, and the temperature was
measured by the doublet method (Na). The maximum temperature of the
combustion products was 24000K. When the temperature was increased in the

range under consideration (1600 - 24000K)., the experimental values of
conductivity deviated from theoretical data (Fig. 1), but the theoretical
dependence of conductivity on partial pressure of the additive remained
valid. This shows that conventional methods (M. H. Saha. Phys. Mag., 40,
472, 1920; Chapman, T. Cowling. Matematicheskaya teoriya neodnorodnykh
gazov (Mathematical theory of inhomogeneous gases), IL, 1960) cannot be
used for calculating conductivity of ionized products. The deviations
may be due either to a relatively random value of 0, ( ~j - 10-15 cm2, having
been chosen and considered constant for the given temperature range) or to
the mechanism of the vanishing of electrons. There are 1 figure and I

ABSTRACT: Vie effect of a pia tic field on the electroconductivity of a gaseo-as
mixture has been investigated. It is shown that while electroconductivity
re a' onstant along the magnetic field, it varies in the transverse direction
with field strength. To. find the conditions for maximum transverse
"electroconductivity of a mixture of a practically nonionizable diluent gas with a
seeding vapor in the presence of a magnetic field, the optimim seeding ratio as a
function of intensity of the magnetic field-vw sought. It is found that at a
fixed pressure and a value of H at which the optimun concentration of the seeding
vapor is still relatively smail, this concentration practically ceases to depend
on the nature of the diluent.

-,-ABSTRACT.- The products of combustion of hydrocarbon fuels are suitable for investi-
.,gation of the properties of weakly ionized gases. In such combustion products with
some appropriate readily ionized material added one can independently vary the two
-fundamental parameters that determine the conductivity of the gas, namely, the elec-'
.:tron concentration and the frequency of collision of the electrons with the heavy
particles. Increase of the gas conductivity Is important for many studies. In the
;present work there were investigated the combustion prodwto of methane-air and me-.

,,.ithane-oxygen mixtures, all at atmospheric pressure. The temperature was varied by
changing the 'composition of the mixtures. The ionizing additive - potassium - was 1
.introduced into the air or oxygen In the form of K2CO3 solutions of different con-
lcentrations. The temperature of the combustion products was determined by observa-
Ition of reversal of the sodium doublet. The conductivity of the gas was determined
by three procedures: measurement of the attenuation of radiowaves, measurement of
',the change in the Q or frequency of a circuit including a cooled coil filled with
::the medium, and measurement by means of probes. The three procedures are described
eand it is noted that the probe method has generally been used only in the region of,
-~:low pressures. The results are presented in Fig.1 of the Enclosure for four values
~;of X partial pressure. The results are consistent and indicate that the conductivi-
ty of the gas varies in proportion to the square root of the partial pressure of the
''easily ionized additive. Thus, all three conductivity measurement procedures can be,
ilions. "Me authors are grateful to Prof L. N. Xhitrin fdr!
