Abstract We performed a characterization of the bubbly and slug flow regimes in minichannels in conditions relevant to microgravity. Two-phase flows were generated on ground by means of a T-junction device (1 mm i.d.), whose operation is independent to changes in gravity level [1]. Air and water were injected at several superficial velocities ranging from 0 up to 2 m/s. The generation and detac...

This paper presents an algorithm for numerical modeling of bubble dispersion occurring in the near-surface layer upper ocean under action non-breaking two-dimensional (2D) surface waves. The is based on a Eulerian-Lagrangian approach where full, 3D Navier-Stokes equations carrier flow induced by waved water are solved Eulerian frame, and trajectories individual bubbles simultaneously tracked La...

Multi-port microchannel tubes are increasingly popular for use in a variety of heat transfer applications, primarily for automotive condensers and radiators, but also in a variety of refrigeration and air conditioning applications. These channels offer a greater surface area to volume ratio, providing for enhanced heat transfer over a conventional tube in many applications. Previous research ha...

Liquid spreading through a randomly packed particle-resolved bed influenced by capillary or inertial ( $AB_s \sim 1$ ), and gravitational force (moderately 0.1$ ) strongly 0.01$ )) is investigated using the volume-of-fluid simulations. The relative contribution of governing forces at different stages analysed time evolution Weber $We_I$ $AB_I$ numbers. We show that dynamics liquid primarily gov...
