Accelerating Taylor bubbles within circular capillary channels: Break-up mechanisms and regimes

Abstract In the present paper, an enhanced Volume of Fluid model is applied for conduction parametric numerical simulations, to investigate break-up phenomena accelerating, elongated, vapour bubbles, within circular mini-channels. The effect fundamental controlling parameters in resulting characteristics investigated. Four different series simulations isolated bubbles mini-channels are performed, examining effects imposed pressure difference between inlet and outlet channel, surface tension, heat flux as well initial liquid film thickness on developed vapour/liquid interface dynamics. overall dimensionless number ranges examined 6.76
