碩士 === 國立臺灣科技大學 === 化學工程系 === 94 === This laboratory uses pendant bubble tensiometer, measures the dynamics and equilibrium surface tension among the interface of the gas-liquid, and calculates to get the Frumkin isotherm theorem model and the best parameter by the equilibrium surface tensionγ(C), then uses the classical spherical model to discuss the surfactant adsorbs to the bubble and dynamics surface tension, and simulates the diffusion coefficient, but real system needs to think the needle effect and pendant bubble among the real interface of the gas-liquid. In this research, use the best parameter and diffusion coefficient of CSM system, and use the pendant bubble finite element model to study the needle and the shape of bubble influence with dynamics surface tension again.
