# In addition to the residence time T SL

In this section we examine the flame Navitoclax in a long but finite channel of length ??. To this end, the complete two-dimensional time-dependent Eqs. (1), (2), (3), (4), (5) and (6) were solved for selected values of the parameters. The time marching calculations were carried out in a similar way as proposed in [17], where the velocity was decomposed into irrotational and solenoidal components and solved respectively by introducing potential and stream-like functions. The pressure has been eliminated by solving the vorticity instead of the momentum equations and conditions (7) satisfied by imposing the constraint∫0?ζyy=0dx=0obtained when Eq. (2) evaluated along the walls-px+Pr-ζy+43a2vxy=0is integrated along the channel and use is made of the boundary conditions at x=0,?x=0,?. The initial conditions adopted correspond to a hot spot near the left end of the channel in a mixture commensalism is otherwise at rest. The position of the flame front xf(t)xf(t) was defined as before as the location where the reaction rate ωω reaches its maximum value along the mid-plane and the corresponding propagation speed x?f was subsequently determined by differentiation.
