This paper details the development of noninvasive ultrasonic tomography for imaging liquid
and gas flow. The transmission-mode approach has been used for sensing the liquid/gas …

In this study, bubbling fluidization of a sand fluidized bed with different biomass loadings are
investigated by means of the experiments and numerical simulation. The radioactive particle …

Noninvasive monitoring of multiphase flow is rapidly gaining increased interest. More
specifically noninvasive particle tracking techniques have received a lot of attention in recent …

Gas–solid fluidization is a well-established technique to suspend or transport particles and
has been applied in a variety of industrial processes. Nevertheless, our knowledge of …

An experiment has recently been carried out to recognize the flow pattern and to measure
the void fraction of gas–liquid two-phase flow in vertical upward pipes at Xi'an Jiaotong …

Reviews and compares the major types of bioreactors, defines their pros and cons, and
identifies research needs and figures of merit that have yet to be addressed Describes …

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

Local bubble characteristics, including gas holdups, bubble rise velocities, and chord
lengths, were measured using a monofibre optical probe manufactured to withstand …

In granular flow operations, often particles are nonspherical. This has inspired a vast amount
of research in understanding the behavior of these particles. Various models are being …

Developing technology for the deep-sea mining of polymetallic nodules requires, theoretical
analyses, simulation and numerous experimental studies. In this paper authors focused on …
