Abstract
A theoretical analysis of a two-phase particulate electrogasdynamic flow is presented. The effect of the space charge induced electric field force on the solid particle charge carrier is included. The direct conversion of kinetic energy into electricity is accounted for by the electrical body force work term in the energy equation. A sample solution to the seven, ordinary, nonlinear, coupled, differential equations is presented for a typical electrogasdynamic energy conversion channel, L/D = 13. Results for the axial pressure, electric current, and potential distribution are given, as well as particulate and gas phase velocities and temperatures for 100 fj. diameter particles at two mass-loading ratios of MP* = 0.1 and MP* = 1.0. Nomenclature A = flow channel cross-sectional area, m2 j$F ^ = body force nondimensional parameter, dimensionless Bg = interphase heat-transfer parameter, dimensionless cg — specific heat of gas phase at const ant pressure, cal/g°K DH = flow channel hydraulic diameter, m D — flow channel diameter D = DH for a cylindrical flow channel, m dp =
