“…The pressure drop coefficient could be calculated from the pressure drop using the polynomial graph, as shown in Figure 2. Different materials, fluids, dimensions, and conditions result in different pressure drop coefficients and viscous and inertial resistance based on the heat sink study [13]. Based on the graph obtained, the pressure drop coefficient of the N95 filtration layer is ΔP = 50352v 2 + 188.05v + 20.055.…”

Due to the general confusion over the mask's efficiency against COVID-19 virus droplets, professionals and the public may find it difficult to stop the disease from spreading. This study intends to investigate the fluid flow across the N95 filtration layer based on the experimental data and create a simulation model based on the analysis. Therefore, the fluid flow across the filtration layer is simulated using ANSYS Fluent, part of Computational Fluid Dynamics (CFD) solver software. This study anticipates the fluid flow across the N95 by using the porous media approach, in which inertial resistance and viscous resistance are introduced in the simulation by obtaining the pressure drop coefficient of the actual 3M N95 filtration. The fluid passed through the filtration layer with some velocity range based on the MS 2323:2010 standard. The pressure and velocity distribution of fluid through the filtration layer are analyzed by simulation illustration of the contour and streamline of the fluid. For most conditions, as fluid flowed across the filter, the flow gradually began to retard and diverge around the filtration layer. Besides, different flow rates across the filtration layer also result in different pressure distributions on the N95 layer. To sum up, this study is beneficial in forecasting the fluid behavior across the filtration layer by applying the porous zone approach in the ANSYS simulation.

The drastic technological growth and development of advanced computer processors leads to a serious problem due to the generation of heat. Modern processors are designed in such a way that even though small in appearance their performances are beyond our thought. The performance of processors directly depends on the heat they generate. The heat generated while processing is generally considered as waste heat that needs to be removed immediately before it could fail the heat sensitive components present inside the processor. There comes a problem of removing this waste heat. Bridge Rectangular Fin Heat sink (BRFHS) is an object having a single base and fin-like protrusions made of aluminium and pyrolytic graphite material because of their high thermal conductivity. ANSYS Fluent CFD Version 12.1 software package was used for simulation. Air is used as a fluid and a comparative study was done for the same heat sink configurations between the aluminium and pyrolytic graphite. In this work, the effect of angle of fin changes was also analysed for aluminium and pyrolytic graphite. It was found that at a fluid velocity of 1.2 m/s, the maximum fin temperature for aluminium was 320 K while and that for pyrolytic graphite was 310 K. The optimum cooling is achieved by BRFHS having an angle of 22.5° simulated with pyrolytic graphite material at 1.2 m/s air velocity. The maximum temperature found on the fin after dissipation of heat was 302 K which is very near to the ambient temperature.

“…Finite elements computational fluid dynamics (CFD) simulations were carried out with the ANSYS Fluent software package (free academic resource version). This software incorporates a porous media model that can effectively represent the open pore foam systems herein proposed [30,31]. The pressure drop for the fluid passing across a sample can be accounted for with the well-known Darcy-Forchheimer equation, which combines two terms associated with viscous and inertial losses (first and second terms, respectively, on the right-hand side of the following equation):…”
