Gas density affects the gas holdup in bubble columns. Even at atmospheric pressure, different gases produce varying gas holdups. This contribution explores the causes for variations in gas holdups occurring for different gases. Differences in the bub

This contribution discusses the influence of material wettability on gas/liquid flow and reaction in capillaries. It is shown that the performance of microfluidic devices as chemical reactors can be enhanced by choosing wall materials promoting wetta

The solubility of carbon dioxide in binary mixtures of water and methanol containing up to 12.37 mass % methanol has been measured at temperatures between 298 K and 333 K at atmospheric pressure. The solubility increases with increasing methanol cont

The contact angle of a gas-liquid-solid system plays a significant role in predicting flow patterns in microchannels for multiphase flows. The contact angle, which is a result of surface forces, is strongly influenced by the channel material. In the
