Introduction Fluid flow patterns in research or process-scale equipment where a fluid is contained between concentric rotating cylinders in the absence of bulk axial flow has received notable attention in the field of fluid mechanics. Annular flows occur in many practical applications, such as in the production of oil and gas, fluid viscometers, centrifugally-driven separation processes, ...

Chemical vapor deposition is considered a promising method for synthesis of graphene films on different types of substrate utilizing transition metals such as Ni. However, synthesizing a single-layer graphene and controlling the quality of the graphene CVD film on Ni are very challenging due to the multiplicity of the CVD growth conditions. COMSOL Multiphysics® software is used to investigate ...

A 3D finite element analysis is carried out, using COMSOL® software, to reproduce the thermal profile obtained with Rosenthal’s equation. The implemented heat transfer equation has been modified as a means to approximate Rosenthal’s solution. An analysis of the differences between the simulation and Rosenthal’s solution, when the geometry of the domain and the source are changed, has been ...

Introduction: Existing solar cell (photovoltaic, PV) device simulation software is either open source with limited capabilities (1D only) [1,2] or extremely expensive with obscure functionality . PV researchers need an accessible and versatile simulation tool to optimize existing technologies and to reduce the time from concept to prototype for new technologies. This work demonstrates how ...

Dilution’s issue during dry machining have raised the interest’s environmental researchers and engineers. In fact, the sampling of dust emitted during dry machining was a serious problem for air quality evaluation at the workplace. Furthermore, the best sampling of fine and ultrafine particles produced during material cutting, passed through the dilution of high particle concentration (number, ...

This paper deals with the simulation of mathematical model for supercritical extraction. Reverchon, 1996 extracted sage oil using supercritical extraction method from sage leaves at 9 MPa and 50 ᵒC. Four mean size of sage leaves ranging from 0.25 to 3.10 mm were taken for extraction with other experimental conditions and process parameters. Experimental results were fitted in the model developed ...

Polymer hydrogels are commonly used as carriers or vehicles for the controlled release of drugs, primarily because of their bio-compatibility and because rates of drug release can be controlled by manipulating polymer properties like molecular weight, cross linking ratio, etc. Drugs can be released for prolonged periods of time through polymer hydrogels [1, 2]. Sustained drug release may ...

A lithium-ion battery comprises of two intercalating electrodes separated by a membrane, sandwiched between aluminum and copper current collecting plates. The battery performance depends upon several parameters and its operating conditions. In this work we developed a model for a lithium iron phosphate battery and validated our results with experimental charge-discharge curves. We however note ...

Fuel vapor restraint systems are used in vehicles to avoid discharge of volatile hydrocarbons from fuel tanks. The topic of this paper is the proper operation of fuel vapor restraint systems depending on the composition of bioethanol-fuel-blends. Experimental data serve as input to a model built with COMSOL Multiphysics® to simulate the performance of fuel vapor restraint systems depending on ...
