Abstract • This paper describes a computational study of the thermal and chemical nonequilibrium occuring in a rapidly expanding flow of high-temperature air transported as a free jet from an orifice into low-density stationary air. Translational, rotational, vibrational and electron temperatures are treated separately, and in particular the vibrational temperatures are individually treated; a multi-vibrational temperature model is adopted. The governing equations are axisymmetric Navier-Stokes equations coupled with species vibrational energy, electron energy and species mass conservation equations. These equations are numerically solved, using the second order upwind TVD scheme of the Harten-Yee type. The calculations were carried out for two different orifice temperatures and also two different orifice diameters to investigate the effects of such parameters on the structure of a nonequilibrium free jet.

Abstract A number of substituted symmetrical dithiodiphenols and related monothio-and trithiodiphenols were prepared and characterized. Some of these dithiodiphenols showed chain transfer activity either in bulk styrene or in emulsion diene polymerizations. The fact that phenolic sulfide units were incorporated into polyisoprene and polybutadiene by use of one of these compounds, 2,2′-dithiobis(6-t-butyl-p-cresol), as chain transfer agent was confirmed by ultraviolet analysis. It was demonstrated that selfresistance to oxidation was incorporated into various diene homo- or copolymers, to varying degree, by use of some of these dithiodiphenols as chain transfer agents, on the basis of oxygen absorption tests on preextracted polymers.
