Rotational-level-dependent Quenching of Oh(a ‘x+) at Flame Temperatwres

The collisional quenching of OH(A’X+, u’ =O) is studied by laser-induced fluorescence in the burnt gases of low-pressure (7 Torr) stoichiomctric HZ/02/NZ0 flames. The tcmpcrature of these flames is adjusted between 1200 and 2300 K by altering the C&/N,0 mixing ratio. The variation of the quenching rate constant with rotational level in the OH(A) for HZ0 collider is substantially less at 2300 K ...

Remarks on Quenching 201 Quenching Occurs

Consider the parabolic problem u t div (a(u;ru)ru) = u p (1) for t > 0, x 2 R n under initial and boundary conditions u = 1, say. Since p is assumed positive, the right hand side becomes singular as u ! 0. When u reaches zero in nite or in nite time, one says that the solution quenches in nite or in nite time. This article gives a survey of results on this kind of problem and emphasizes those t...
