Fluid Dynamics: Flame front in a channel

  1. May 13, 2009 #1
    A flame front accelerates exponentially in a channel of width 2R with non-slip boundary conditions at the walls. Flame acceleration creates pressure gradient -deltaP/density=exp(sigma*t) (x-direction) directed parallel to the channel walls.

    Assuming a plane-parallel flow, find velocity distribution in the channel.

    I started with the Navier-Stokes equation and because of the plane-parallel flow and pressure gradient I came to this equation:


    But now I don't know how I will continue, someone has an idea? Maybe I'm on the wrong track?
