An experimental and theoretical study of electron energy dissipation in a flowing stream

Abstract

Experimental data show that the efficiency of an irradiation process, ε, of the flowing water is related to water flowrate. In this work, we introduce a new formula for water flowrate which parameters ε and dose distribution well related to the flowrate are derived, analytically. First, in terms of stream velocity, electron fluence is defined then, the accepted concepts of an electron beam irradiation processing are rewritten in flowrate dependence using the experimental data of ε versus flowrate and initial electron energy. The final formula predicts the depth-dose distributions respect to the flowrate. Also, we propose an analytical formula for D(t) and further for Fe and ε in terms of the flowrate with definition of C1 parameter as a correlation factor of velocity on the surface and in the bulk. Further, the simulation approach shows flowrate dependence of the depth-dose curve well.
