The over-all objective of the present studies is to construct a satisfactory working model of the transpiration of a fluid medium through a porous anode into a DC electric arc. The emphasis is on the effects of electrode and working fluid properties on the energy transfer and arc characteristics under different conditions of transpiration flow rate and arc power. The experimental work described includes physical characterization of several chosen porous anode materials in terms of porosity, pore structure, gas flow permeability, thermal conductivity, and local flow field studies. The construction of a flexible fluid transpiration arc test equipment is presented. The first approach to the analytical studies of fluid transpiration cooling is described.
