The laminar flame propagation speed was analyzed theoretically with two methods and the expression of the laminar flame propagation speed was described when the quenching distance is under consideration.

In this paper, a limiting problem for an optimal boundary control problem of a laminar flow of a viscous incompressible fluid in the generalized Couette cell, when the number of inner cylinders unrestrictedly increases, is obtained.
The calculation procedure of electric-simulation method for the solution of boundary-layer equation is proposed. The calculations of the laminar velocity of a fluid flowing along a flat plate as well as at the entrance of a circular pipe were given as examples to illustrate the correctness of this method. It seems to be particular useful for the solution of those problems where complex boundary conditions, variable physical properties, large temperature gradients etc. are concerned.
With the method suggested by Wang Bu-xuan[4] an approximate theoretical analysis has been presented for steady laminar flow heat transfer of Bingham fluid through a circular tube. Equations have been derived for both boundary conditions, tw=constant and qw=constant. Numerical values of average Nusselt number have been calculated and compared with Hirai's data[1,2] with good agreement.
By considering the behaviour of the reaction zone development in the ignition process, the turning point in the course of expansion is accepted as the criterion of ignition. The ignition process of combustible gas stream by a heated plate in the laminar boundary layer was analytically considered and the limits of ignition were determined. In the second part, the ignition process of combustible gas stream by its combustion produces was studied both theoretically and experimentally. This sort of ignitio...
