A series of laboratory experiments was conducted to improve the entrainment and mixing
capacity of vertically discharged bubble plumes by employing a grid-screed with different …

The mixing uniformity plays a crucial role in a liquid-liquid two-phase chemical process. To
quantify the uniformity of the liquid–liquid process, the specific surface area ratio is proposed …

Bubble characteristics such as shape, size, number and motion control the hydrodynamics
and therefore heat transfer and chemical conversion in fluidized bed reactors. Thus …

A fast response heat transfer probe was designed to measure local instantaneous heat
transfer coefficients at various gas velocities and slurry concentrations in a slurry bubble …

An understanding of the bubble properties, size distributions and shapes and their ability in
various applications is of fundamental importance for comprehending flow dynamics and …

Water and air are usually employed as a heat exchange medium in cold channels of a plate
heat exchanger (PHE), while air, in the state of bubbles in water, has an apparent impact on …

The aim of this work is to investigate the turbulent hydrodynamic features of a fully baffled
gas− liquid stirred vessel equipped with a dual turbine consisting of a radial concave-blade …

Abstract" In this study, the impact of configuration and size of vertical heat exchanging
internals in bubble columns on gas holdup, specific gas-liquid interfacial area, bubble chord …

A precise estimation of bubble size distributions and shapes is required to characterize the
bubble column fluid dynamics at the “bubble-scale”, and to evaluate the heat and mass …

Bubble columns are widely used in chemical and biotechnological process industries. The
important reasons for this wide usage are the simple construction, without moving parts, and …
