- W323008429 abstract "This study was conducted to further investigate parameters affecting the dispersion of argon in polybutene. (Argon and polybutene were chosen as model fluids to simulate the dispersion of radioactive krypton and xenon in molten glass.) The experimental apparatus used was a cylindrical lucite chamber equipped with a variable speed impeller, gas and polybutene inlets, foam withdrawal ports, and pressure and temperature measurement capability. The effects of input power, impeller blade pitch and liquid flow rate on gas loading and viscosity were studied. It was found that at a constant input power to the impeller motor of 155 w, impeller blade pitch had no significant effect on gas loading. An increase in input power was found to increase gas loading, but indications were that maximum gas loading at zero liquid flow rate was independent of input power. The maximum gas loading obtained was 23 percent at 6900 rpm with a liquid flow rate of 165 ml/min and input power of approximately 190 w. A model based on bubble formation rate as a function of power input and gas loading was postulated to characterize the dispersion mechanism. The viscosity of the foam at various gas loadings was measured. It was found that up to 23 percent gas loading, the foam exhibits Newtonian characteristics and that the foam viscosity was greater than that of pure polybutene at the same temperature. No trend was observed between the foam viscosity and the percent gas loading. Fluid temperature had a large effect on viscosity, but the effect was not investigated fully. It is recommended that future work be done to substantiate and further develop the proposed model of the dispersion mechanism, and to determine the effect of viscosity on foam formation. Such studies would provide guidelines for extrapolating experimental results obtained with the polybutene model fluid to molten glasses with somewhat different fluid properties." @default.
