Transfer Phenomena Influence on Energy Efficiency of Plasma-Chemical Processes

Transfer Phenomena Influence on Energy Efficiency of Plasma-Chemical Processes 

Transfer phenomena do not change the energy efficiency limits estabhshed by absolute and ideal quenching (see Section 3.6.6) if (1) binary diffusion coefficients are fixed, equal to each other and to reduced coefficient ofthermal conductivity (Lewis number Ze = I, Sap = 

0) (2) effective pressure is constant, which implies an absence of external forces and large velocity gradients. To explain this rule, consider the enthalpy balance and continuity equations (Section 3.6.7) in the steady-state one-dimensional case  

Introduce dimensionless functions for reduced enthalpy and reduced mass fractions  

The boundary conditions for these equations on the left and right sides of the region are
