Abstract

Abstract: Three-dimensional CFD technology is applied in a RADICL model by solving laminar Navier-Stokes equations and transportation equations to study iodine molecule dissociation rate,iodine atom pumping rate,singlet oxygen yield rate and small signal gain at different flow rate ratio of primary and secondary flow.It is found that an appropriate flow rate ratio plays an important role in spatial distribution of the small signal gain.Rich or poor oxygen conditions go against with a proper gain.

Key words: COIL, jet in cross flow, flow rate ratio, gain

CLC Number:

TN248.2
