Among the different thermo-chemical recycling routes for plastic waste valorization,
gasification is one of the most promising, converting plastic waste into syngas (H2+ CO) and …

Hydrological droughts are characterized based on their duration, severity, and magnitude.
Among the most critical factors, precipitation, evapotranspiration, and runoff are essential in …

In flotation, a bubble acts as a carrier for attached particles. The properties of the gas–liquid
interface of the bubble are one of the main factors determining the bubble motion and …

Microalgae are the third generation of biomasses that have received lots of attention due to
their high energy content and ability to capture carbon dioxide from the air. However, there …

The bubble generation performance and liquid volumetric mass transfer coefficient k L a of
the venturi microbubble generator and the swirl-venturi microbubble generator were …

Bubble columns are gas–liquid contactors that are used in many process-engineering
applications. A counter-current liquid flow is frequently imposed to adjust the bubbles' …

Bubble size distribution (BSD) is a crucial parameter in the design and scale-up of slurry
bubble columns (SBCs) as it affects the hydrodynamics, heat and mass transfers, and …

Prediction of gas holdup and bubble size distribution is of paramount importance for
modeling mass and heat transfer and reactions in multiphase reactors. Addition of …

Power consumption and oxygen transfer are considered the two most important direct
indexes, affecting the effective and cost-efficient C5 sugar acid fermentation from C5 sugar …

As a conventional and persistent topic, a single bubble freely ascending in Newtonian
liquids is investigated based on its shape and motion predictions using the strategy of …
