The two-fluid model of turbulence applied to combustion phenomena
bx = body force component in x direction Cf = interfluid friction constant Dj = diffusion flux of fluid / fy = volumetric interfluid friction coefficient fiw = volumetric fluid/wall friction coefficient gi = generalized flux of phase / £ = reciprocal of interface area per unit volume mi mass transfer rate into fluid / per unit volume p pressure TI volume fraction of fluid / t = time u = velocity in x direction YI = velocity vector of fluid / pt = density of fluid / r = reactedness = general conserved fluid property $ = source of entity measured by
