The mixer-settler principle is commonly used for industrial extraction processes. This is done by mixing the two immiscible liquids to perform mass transfer and subsequently separating them in gravity settler. However, when drop size becomes small, separation in a settler becomes difficult and entrainment of valuable chemical occurs. Moreover, entrained impurities dilute the product. ...

The objective of this study is to numerically evaluate the effectiveness of an energy recovery ventilator (ERV) during the summer and winter seasons. The energy recovery ventilator allows heat and mass transfer between two air streams separated by a membrane. The effects of varying the following parameters were examined: flows through the supply and exhaust ducts, height of the exhaust channel, ...

Scraped surface heat exchangers (SSHEs) are commonly used in the food, chemical, and pharmaceutical industries for heat transfer, crystallization, and other continuous processes. One of the factor posing difficulties to heat transfer is viscosity. Highly viscous fluids tend to generate deep laminar flow, a condition with very poor heat transfer rates and high pressure losses involving a ...

Mathematical optimization can be used as a computational engine to generate the best solution for a given problem in a systematic and efficient way. In the context of monolithic converter systems, the parameter estimation problem (or inverse problem) is solved using Partial Differential Equations (PDE)-based models of the physical system coupled with an optimization algorithm. These problems are ...

Lithium-sulphur (Li-S) batteries have the potential to surpass the energy storage capability of Li-ion batteries due to their high theoretical gravimetric energy density of 2700 Wh/kg. However, the processes which drive the system behaviour are much more complex than those in a Li-ion cell, meaning that controlling them to realise energy densities much above 350 Wh/kg is challenging. In a Li ...

Electroporation is a highly efficient cellular transfection method which is used to inject molecules into living cells. The electroporation involves creating temporary pores in cell membranes using an electrical field. It has been successfully utilized in medicine and biology for producing knockout mice, gene therapy, and cell-based therapy. As electroporation is an easy and rapid method, it is ...

Fixed nitrogen is used in many forms ranging from nitric acid to hydrogen cyanide and is used as such for industrial applications. The reactions to produce these products are highly endothermic and favored by high-temperature processing. The most basic route of chemically fixing nitrogen is the direct reaction of nitrogen and oxygen. However, the major challenge is to supply very high ...

The use of numerical techniques in PEM fuel cell sensoring represents an advantage of project engineering, reducing the costs and accelerating the manufacturing of prototypes. In this work some numerical responses are shown, relating to numerical sensoring of water and oxygen mole fractions at cathode of a 5 cm² of geometric area PEM fuel cell. The need to recognize a geometric figure of merit ...
