We demonstrate a simple example about how to design my own algorithm for Navier-Stokes equation by weak form PDE and LiveLink™ for MATLAB®. After the computation, we get the same solution as other FEM packages (FreeFEM++ & FeniCs) at each iterative step, and we can see the Navier-Stokes equation’s solution at error between each step. This attempt gives algorithm researchers a hint or a ...

This paper is focused on topology optimization of heat transfer and fluid flow systems for multiphysics objectives. Specifically, COMSOL Multiphysics software is coupled with a method of moving asymptotes optimizer in a custom COMSOL / MATLAB script. Various physical process including conduction, convection-diffusion, and Navier-Stokes flow are considered. To illustrate the method, a standard ...

The conductivity of seawater directly correlates with the concentration of dissolved salts. This model demonstrates a new approach to the methodology of inductive conductivity measurement of seawater and other liquids. COMSOL Multiphysics® was used to build a parametrically swept model of an O-Core Inductive Conductivity Measurement Sensor for Seawater. This sensor model is built using the ...

A teaching platform that could be used to help students understand concepts such as; flux linking and mutual inductance has been developed using the AC/DC Module of COMSOL Multiphysics®. This is achieved through the accurate determination of different magnetic flux density components within the proposed geometry. Furthermore, based on the structure configuration, students can use obtained ...

Energy harvesting from environmental vibration nowadays is feasible because of natural oscillations like that caused by air or liquid flow and by exhalation or the heartbeat of a human body. This vibration frequency is typically low (in order of less than 1 kHz). Accordingly, low-frequency vibration based energy harvesting systems are an important research topic; these systems can be used for ...

Undergraduate studies are carried out to examine the supersonic flow from an axisymmetric converging-diverging nozzle. Flow in the nozzle is initiated by the rupture of a diaphragm that is positioned between the nozzle and a 1-gallon pressurized air tank. Simulations are carried out in COMSOL Multiphysics® for unsteady, axisymmetric flow with the High Mach Number interface of the CFD Module. ...

Pressure Sensors are widely used in the automotive industry. Their main use is the dynamic monitoring of pressure inside combustion engines. To achieve a good signal accuracy, the design of pressure sensors can be improved with FEM calculations of stress and strains on the measuring cell depending on their geometry and material properties. The geometry is adapted according to a special ...

A web based visualization solution for three dimensional simulation results of COMSOL Multiphysics® is described. With it, mobile clients with low bandwidth as well as desktop computers with high bandwidth connections get able to show simulation results without the need of installing specialized software. To do so, a modern web browser is required. Both touch gestures and common input techniques ...

In this work we solve a model to simulate the drying of potatoes slices. The model considers both the transport of free and vapor water by applying a mechanistic approach. The critical moisture point (CMP) was considered, since it is a transition zone and it represents the point where water saturation is near from cero and hygroscopic domain begins. The CMP divides the hygroscopic and ...
