本實驗室利用影像數位化懸掛氣泡表面張力測量儀,量測氣-液界面間的動態與平衡表面張力,再經由平衡表面張力γ(C)計算獲得吸附恆溫線Frumkin isotherm理論模式之最適化參數,以傳統球狀氣泡模型(classical spherical model )來討論界劑吸附至氣泡表面的動態表面張力變化,並模擬出的擴散係數,但真實系統尚須考慮到針頭之存在與懸掛氣泡之真實氣-液界面。本研究使用CSM系統之最佳參數和擴散係數,再以懸掛氣泡之有限元素模擬模型(pendant bubble finite element model)進一步探討針頭效應與真實氣泡的形狀效應對動態表面張力變化之影響。
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.
