A misusage of machine learning (ML) strategies is usually observed in the process systems engineering literature. This issue even more evident when dynamic identification performed. The root this problem gradient explode and vanishing related to recurrent neural networks training. However, after advent deep learning, these issues were mitigated. Furthermore, data structuration often overlooked during model field. In scenario, work proposes a guideline for identifying ML models different...
This work proposes an innovative high-intensity mixer based on the NETmix technology to promote contact between ozone (O3) gas and water. The consists of a network unit cells comprising mixing cylindrical chambers interconnected by prismatic channels. Its exclusive geometry generates successive contacting splitting flows, boosting mass transfer rates rapidly developing O3-enriched liquid stream. gas-liquid performance was evaluated measuring volumetric coefficient (kLa), standard oxygen...
This study evaluates a 2D two-phase computational fluid dynamics (CFD) model, based on the Volume-of-Fluid approach, to represent air–water co-current downwards flow inside micro/meso structured static mixer, NETmix. The model was suitable for representing properties more reliant upon shape and size of bubbles, such as gas hold-up. Additionally, it measured pressure drop associated with NETmix, through which observed capability NETmix operate at lower than some common mixers. Using both CFD...
The unit cells of the micro/meso-structured static mixer NETmix consist cylindrical chambers connected by prismatic half-channels. These elements are defined their characteristic geometrical properties: chamber diameter, channel length and width, as well depth. This study analyses effect two properties, depth, on gas-liquid mass transfer performance NETmix. Four plates were constructed with different dimensions to experimentally assess volumetric coefficients under operating conditions....
The main goal of this work was to design a new product containing an active ingredient the Eucalyptus Globulus tree - its essential oil. This divided into four steps: analysis raw material, chemical (needs, ideas, and selection), manufacture, economic analysis. After investigating potential all selected plaster in gel, named Eucatrigel, with triple action: it protects wound, accelerates healing (due oil addition), waterproofs region. In manufacturing step, defined mass percentage gel as 0.5...
