Abstract:

Objective: This study investigated the optimization of thermal energy consumption using electrochromic components with a new nanocomposite layer (WO3+Ag) in a larger size (window) for a room with an educational application for five cities with different climatic conditions in Iran (Yazd, Tehran, Bandar Abbas, Tabriz, and Sari).

Materials and Methods: For this simulation platform, the software was implemented in Energy Plus. This feasibility study was modeled by DesignBuilder software which reported reduced thermal energy consumption across all climates in Iran (hot and dry, warm and semi-humid, warm and wet, moderate and dry, and mild and humid.). Four strategies were considered for better comparison. The first strategy used for common double-glazed windows, while the second to fourth strategies involved the use of the electrochromic window in three different modes; bleached mode (Off), colored mode (On), and switchable mode (controlled below comfort conditions).

Results: The third and fourth strategies indicated a reduction in thermal energy consumption in different climates from 25 to 45% relative to typical windows. The best result of cooling energy consumption was observed in Tehran.

Conclusion: For this climate, the average energy consumption dropped to 34% for the warm months of the year and even 42% for the warmest month of the year (August). To read out more, please visit: http://www.eurekaselect.com/170061/article

EDITOR’S CHOICE – Micromixing Enhancement by Optimizing the Geometry of a Micromixer by Means of Response Surface Methodology – Micro and Nanosystems

Journal: Micro and Nanosystems

Author(s): Joaquin Ortega-Casanova, Pablo Benitez-Alcaide

Graphical Abstract:

 

Abstract:

Objecive: The Response Surface Methodology (RSM) is applied to optimize a passive micromixing unit according to three different targets.

Method: To that end several numerical simulations of the low Reynolds number flow in a micromixer, comprising a T-channel and a mixing unit in the main channel, have been conducted. The mixing is enhanced by means of two bars at known angles inside the mixing unit. The input parameter of the optimization process is the distance between bars and, depending on the desired target, different optimal separations are proposed. It has also been assessed how different mixing parameters change when multiple repetitions of the mixing unit, up to 10, are used in the microchannel.

Conclusion: This has allowed us to identify the use of 10 units as the best configuration to get the highest efficiency, but the use of 1 unit as the cheapest one, from a mixing cost point of view. Additionally, some configurations have also been assessed as potential chemical microreactors, and it will be shown that they perform better as microreactor than as micromixer.

Article by Disease – “Numerical Simulations of Tensile Tests of Red Blood Cells: Effects of the Hold Position”

ARTICLE BY DISEASE ON “HAEMATOLOGY”

Abstract:

Tensile tests have been carried out to determine the failure strain of red blood cells. However, difficulties in reproducibly arise due to problems controlling the hold position of the cells during the test, which raises questions about the reliability of experimental data. Here, we investigate the effects of the hold position of the red blood cell on strain field during tensile testing using numerical simulations. Tensile tests were simulated in three hold positions. The results show significant variations in the deformed geometry of the red blood cell during the tensile test, as well as variations in strain distribution. Of the hold patterns examined, with an applied strain of 0.8, the misaligned stretch increased the maximum of the first principal strain by 65–85% in comparison to the aligned stretch. Although it would be ideal to precisely control the hold position and reproducibility, in practice this is not straightforward, and hence the effects of variations in the hold position should be considered when interpreting experimental data.

EurekAlert! – Blood flow measurements in microfluidic devices fabricated by a micromilling technique

The researchers show the ability of a micromilling machine to manufacture microchannels down to 30 µm and also the ability of a microfluidic device to perform partial separation of red blood cells from plasma.

In this work, Dr. Diana and fellow researchers propose a low cost technique able to produce microfluidic devices for biomedical applications. The most common technique to fabricate biomedical microdevices is soft-lithography. However, it is a costly and time-consuming technique. Progress in manufacturing milling tools smaller than 100 µm, has enabled the use of micromilling machines to fabricate microfluidic devices capable of performing cell separation.
