COMSOL Multiphysics® is used in this study to simulate the flow around a square cylinder and focus on reducing the forces on the cylinder by passive control methods. Numerical simulations are made to find optimum cases of control methods that guarantee maximum reduction for Reynolds number 160 based on the width of the square cylinder (W) and the inlet flow velocity (U_in). The selection of the ...

Single stage centrifugal pumps are widely used in several engineering fields such as: room conditioning, energetic cycles, automotive industry, home care, etc. Thus, the possibility of simulate their behaviour, in terms of pressure increase and mass flow rate, is helpful in reducing prototyping costs in the first design stages. The Rotating Machinery Interface is a dedicated tool implemented ...

One of the most important criteria for evaluating chemical enhanced oil recovery (EOR) processes that use polymers is its rheological behaviour which in turn account for other physical effects of adsorption and resistance factors during polymer-rock interactions. However, complete knowledge of behaviour of polymer solution in porous media has not yet been fully gained. A computational fluid ...

In this paper simulation and parametric study of a PDMS valveless micropump using Fluid-Structure Interaction (FSI) appraoch is presented. The simulation for the valveless micropump were carried out in COMSOL Multiphysics software. In case of a valveless micropump diffuser/nozzle element is connected to a chamber with an oscillating diaphragm. To improve the flow rate of the valveless micropump, ...

A Computational Fluid Dynamics study has been performed for a Gas Electron Multiplier (GEM) detector of high energy charged particles, currently under development as part of a new tracker of the high luminosity spectrometers in Hall A at Jefferson Lab. By gradual modifications of the geometry simulated in COMSOL, the design of the frame separating two GEM foils has been optimized with the aim ...

Hydrocyclones are industrial devices used as processing units in fluid and particle technology. A hydrocyclone is an apparatus consisting of a cylindrical or a cylindrical-conical body with a tangential or involute entrance to admit the fluid inside. There are also two opposite exits, the top exit which is the vortex finder and the bottom exit called apex. Fig. 1 shows the schematic of a widely ...

Localized convection heat and mass transfer can be intensified and optimized by providing exposure to electromagnetic energy. Conjugate heat and mass transfer are configured by solving the momentum, heat and mass transfer simultaneously in both solid (substrate, comprising of a two-phase chemical species) and fluid (auxiliary air) phases. In this way the heat and mass fluxes vary seamlessly ...

The collection efficiency of aerosol particles on a ribbon in a turbulent flow is analyzed using COMSOL Multiphysics. The flow field is solved using Chemical Engineering module and particle tracing plots are obtained using equations of motion including Khan and Richardson drag force. A MATLAB script is used to count the captured particles on the ribbon and determine the capture efficiency with ...

Offshore wind and wave energy industries have developed considerably in the last two decades. Most offshore energy structures used in the existing projects are mono-piles in shallow water due to simplicity of installations, design and control. Numerous research for the design and modeling of offshore wind energy system have been carried out in the past. However, most previous studies have been ...

There are two types of vertical axis wind turbine, drag-type and lift-type. Drag type wind turbine can rotate in low speed wind condition, although its rotation speed is low. Lift type wind turbine can rotate at higher speed, although it works only in high speed wind condition. This study investigates new blade profile that realize rotation in low wind speed condition and higher rotation speed ...
