As known, air quality in urban areas is dramatically affected in particular by the noteworthy presence of respirable suspended particulate matter (such as PM2.5), nitrogen oxides (NOx), carbon monoxide (CO) and hydrocarbons (HC), which are mainly due to traffic-induced emissions. On the other hand, it is also known that vegetation can help restoring the environmental quality of dense urban areas ...

In this paper, we focused on modeling of the piezoresistive pressure sensors. The Structural Mechanics Module of COMSOL Multiphysics® software is used to model the sensor and make a comparative study of the MEMS pressure sensor with different shape and size of membrane. The impact of membrane shape and size on sensitivity and nonlinearity of the pressure sensor is investigated. For example, it ...

Photonic crystals (PhC) are optical nanostructures that are widely known for their strong spatial and temporal confinement of electromagnetic radiation. Here, we study the resonant optical trapping of a single nanoparticle within a hollow circular photonic crystal cavity. The Electromagnetic Waves (emw) interface of COMSOL Multiphysics® was extensively used during the analysis of all our ...

A two-dimensional stationary model of a vanadium oxygen fuel cell is developed in COMSOL Multiphysics®. This energy storage device combines a vanadium flow battery anode and an oxygen fuel cell cathode. The oxygen reduction reaction generates additional water, leading to a degradation of the catalyst performance over time. A logistic function is introduced to the Butler-Volmer equation in order ...

Introduction In order to understand the detection mechanism of the PZT based nondestructive testing (NDT) technology for interface debonding of CFSTs, numerical simulation on a multi-physical model composed of surface-mounted PZT patches and CFST structural member is established in COMSOL Multiphysics®. The stress propagation process and the electrical signal output of an embedded PZT patch as ...

For the lack of higher order modes, lumped element (LE) models currently used may be insufficient to predict the system of balanced-armature receiver (BAR). We develop a LE multimode model for BAR in the frequency domain based on the techniques of mode decomposition, truncation, and selection via COMSOL Multiphysics® software. The validation is made by comparing with both the corresponding ...

In the present work, COMSOL Multiphysics® software was used to solve a mass transfer based mathematical model (Stastova et al., 1996) which is a modified form of Sovova H.,1994 model. The modification has been brought about by introducing the term ‘Grinding efficiency’ in the model and the results of the this model has been compared with the theoretical results obtained by Duba and Fiori, 2015 ...

Ultrafast terahertz photoconductor devices, especially photomixers, are usually limited in output power by device failure thought to be caused by excessive temperatures. Therefore, understanding of thermal breakdown is essential to the study of device reliability and failure of photoconductors. We performed a series of simulations to determine the electronic and thermal thresholds responsible ...

In a first approach towards application of the magnetic frequency mixing technique to microfluidic structures, microplanar coils have to be designed along with sample reservoir. For this, a COMSOL Multiphysics® electrical model along with an analytical calculation is used in order to optimize the dimensions of the coil. This is to ensure a proper distribution and value of magnetic flux density ...

An incremental wear model has been developed using COMSOL Multiphysics® with MATLAB® to predict the evolution of component geometry as a result of wear. Whilst Archard’s wear law is a well-known empirical model for the prediction of wear volume, the design engineer is interested in changes in tolerance as a result of component geometry. At each time step, the simulation extracts the pressure ...
