THE INITIAL SECTION OF A PLANE NONISOTHERMAL
JET DEVELOPING UNDER ASYMMETRIC CONDITIONS
WITH AND WITHOUT COMBUSTION

A solution of the problem obtained with the method
of integral relations is given here. It is obtained in the form of
simple algebraic formulas for the boundaries of the mixing zones on
both sides of the jet, the position of the flame front, and the axis
of the jet at the end of the initial section. It is found that asymmetry
of the boundary conditions has a substantial effect on the characteristics
of the jet: the position of the axis of the jet at the end of the
initial section can change its sign, depending on the temperature
ratio at the boundaries of the jet and for given ratios of the velocity
at the boundaries of the jet to the velocity of the jet outflow, the
length of the initial section can change several fold.
