In this paper, the cyclic voltammetry behavior of Ferrocyanide/Ferricyanide, which is commonly used for electrochemical DNA detection experiment, was studied in the commercial EQCM-D setup (Q-sense) using the COMSOL Multiphysics. The model was established in a 3D geometry of QCM liquid cell. The simulation shows depletion of concentration of ferrocyanice following applied electrode ...

Electrodeposition has a major advantage over other methods of thin film deposition. It allows deposition at atmospheric pressure and room temperature, requiring inexpensive equipment. However, there are several parameters which can influence an electroplated metal layer quality. The current density distribution is taken into consideration. The Hull cell is an electrodeposition tank with a ...

Numerical study of aerodynamic characteristics in steady laminar supersonic flow over a double wedge airfoil is carried out using commercially available finite element based CFD tool COMSOL Multiphysics. The aerodynamic characteristics of double wedge airfoil like lift and drag are analyzed by solving Navier-Stokes equations in the flow field for various thickness to chord ratios (t_c) and angle ...

High Pressure Processing (HPP) is a leading non-thermal food processing technology that is often cited as a major technological innovation in food preservation. Although it is very early to place this emerging technology among the list of breakthroughs in food processing, HPP has started to become a viable commercial alternative for pasteurisation of value added fruits, vegetables, meat, and ...

A new design of electrostatic comb drive actuator is presented in this paper by using different spring designs and with different folded beam lengths. An increased displacement of lateral comb drive actuator will subsequently be accomplished with the same actuation voltage. Stress distribution over different spring designs are simulated by COMSOL 3.5a using a standard comb drive with 4 movable ...

The proposed State of Charge (SOC) governed fast charging method for secondary lithium based batteries charges a battery many times faster than the normal Constant Current-Constant Voltage (CC-CV) charging and reduces the side-effects generally accompanied by various fast charging methods. The proposed charging algorithm takes into account the varying internal impedance of the battery at ...

De Laval nozzles are used in supersonic aerodynamical tubes and engines. They are also employed for the production of cold gas jets to be used in chemical reactions studies. Recently, cold gas jets have been proposed of In-Gas Laser ionization Spectroscopy (IGLIS) The nozzle has a converging and a diverging part with a throat between them. High gas pressure and temperature, and low velocity ...

COMSOL Multiphysics can be used to model a latent heat energy storage system. A 2D numerical study was performed to simulate melting of a PCM including both conduction and convective heat transfer. The heat transfer in fluids and laminar flow physics interfaces were used. To model natural convection, proper volume force was applied to the PCM. The viscosity was input as a piecewise, continuous ...

A dynamic mathematical model, based on physical and transport properties and mass and energy balances, was developed for the simulation of unsteady convective drying of agricultural products (fruits and vegetables) in static bed conditions. The model utilizes water sorption isotherm equations and the change in solid density due to the shrinkage phenomenon. The aim of this article is to describe ...
