It is challenging to measure the hydrodynamics of stirred tank reactors when they contain multiphase flows comprising liquid, gas bubbles and particles. Radioactive particle tracking techniques such as positron emission (PEPT) are only established determine internal flow behaviour due inherent opacity density fluid vessel walls. The profiles solids an important tool for robust reactor design op...

When the ambient temperature is low, a large amount of water mist and dust will inevitably appear around zinc flotation cell, forming haze, which seriously affects extraction froth image features. General defogging methods natural are difficult to obtain satisfactory results for such industrial haze image. Therefore, we propose real-time method based on ASM-VoFD (Atmospheric Scattering Model Va...

Sieve trays are widely used in the gas- liquid contactors such as distillation and absorption towers. In this article, a three-dimensional, two phase CFD model using Euler-Euler framework was developed to simulate a distillation tower with two sieve trays. Hydrodynamic simulation of air and water system in different rates of gas phase was carried out and velocity distribution parameters, clear ...
