Our goal is to reproduce the key features of carangiform swimming by running 2D simulations which fully exploit the Fluid-Structure Interaction interface of COMSOL Multiphysics software. Fish swimming is an important area of research, with relevant developments on biomechanics, robotics and mathematical modeling. Usually, in fish swimming simulations, the motion of the fish is assigned, and much ...

Structural analysis is performed to check the durability of Engine mounts for a given load and support conditions. The engine mount bracket is subjected to loads primarily due to weight of the powertrain and the unbalanced torque. In this analysis, the component is optimized such that stresses generated do not exceed the endurance strength of the material. In this paper, structural mechanics ...

The simulation of the piezoelectric actuation of the micro-cantilever is presented. Lead Zirconate Titanate (PZT) was chosen for the device fabrication design, due to its thin film processing flexibility. Four layers compose the cantilever structures presented in this work: PZT (piezoelectric material), Platinum (electrodes) and Zirconium Oxide as the buffer layer for the PZT film and polyimide ...

Capacitor is mainly defined as two conducting plates that can hold the opposite charges on it. These plates can be used either as a sensor or an actuator. If the relative distance between the two conductors changes as result of given input, then capacitance values will change. This results in basic of capacitive or electrostatic sensing configuration. On the other hand, if a voltage or the ...

COMSOL Multiphysics was used to design a binocular load cell. A three-dimensional linear solid model of the load cell spring element was studied to quantify the high-strain regions under loading conditions. The load cell was fabricated from 6061 aluminum, and general purpose Constantin alloy strain gages were installed at the four high-strain regions of the spring element. The four gages were ...
Scale-up Design of Ultrasound Irradiator for Advanced Oxidation Process (AOP) Using COMSOL Multiphysics® Simulation
The Ohio State University, Columbus, OH, USA
Ultrasound is a promising green technology for the advanced oxidation process (AOP) since it adds no chemicals to the treated water. In this paper, COMSOL Multiphysics® was used as a tool to design and characterize an ultrasound irradiator with multi-stepped configuration, which aims to overcome disadvantages of typical irradiators and to enhance contaminant removal in large-scale water ...

A 2D axisymmetric model was considered in order to evaluate the propagation paths of the ultrasonic waves generated inside an aluminum plate sample due to a rapid thermal expansion produced by laser pulse. Laser Doppler Vibrometer is used to experimentally validate the numerical results of the wave propagation in the material. The presented numerical model is able to identify directivity ...

Introduction: The use of microwave energy for thermal cracking (from thermal stress and water pore pressure) of lignite-coal briquettes increases the lignite friability  and is beneficial for later chemical treatment inside a gasifier (for methanol production for example). An adequate use of microwave energy can improve the overall efficiency of the gasification process based on lignite ...

Air bearings are special type of bearings which provide nearly zero friction between two surfaces. This is achieved by a compressed layer of gas between the surfaces. This study presents a modeling technique for an Air bearing component. COMSOL Multiphysics® is used to efficiently solve a coupled Fluid-Structure Interaction analysis. Computational time is significantly reduced compared to ...
