In this paper, we discuss a simplified finite element method simulation of surface acoustic wave (SAW) delay line hydrogen sensor using COMSOL Multiphysics. A delay line SAW sensor consists of a transmitting interdigital transducer (IDT) and a receiving IDT separated by a few wavelengths. In this work, the number of degrees of freedom to solve for the SAW delay line sensor model ...

Based on solid oxide fuel cell (SOFC) technology, the solid oxide electrolysis cell (SOEC) offers an interesting solution for mass hydrogen production. This study proposes a multiphysics model to predict the SOEC behavior. A global approach and several electrochemical kinetic equations were used for modeling. The simulated results demonstrated that a Butler-Volmer’s equation including ...

Many materials require functionally graded cellular microstructures whose porosity is engineered to meet specific requirements of diverse applications. It has been shown in previous work that the bubble growth rate of a polymeric foam can be influenced by the surrounding acoustic environment and, once solidified, produce a solid of graded porosity. Motivated by the desire to create a flexible ...

Interest in the production of hydrogen from hydrocarbons has grown significantly recently. In order to achieve high surface to volume ratio with reasonable pressure drop, monolithic reactors are used. The goal of this work is to develop a two-phase (gas & solid) transient catalytic combustor model using a simplified flow field inside a single channel to test the advantages of the COMSOL ...

This paper presents and discusses the first phase results of a wide ranging project concerning the study and prediction of the efficiency and energy performances of natural ventilation systems existing inside historic buildings. The air flow patterns, air temperature and air velocity distribution inside a historic building in Florence, the Pitti Palace, were studied by a transient simulation. A ...

The application of nanoparticles coupled with medical agents to brain tumors remains one of the biggest obstacles in neuro scientific research. This work explores an optimal design of an electromagnet to overcome the blood-brain barrier by means of an intensive external magnetic field gradient. It is found that the field gradients depend strongly on the design of the magnet tip. The model ...

Vortex-induced vibration is a major cause of fatigue failure in submarine oil and gas pipelines and steel catenary risers. Even moderate currents can induce vortex shedding. In this paper, COMSOL Multiphysics is applied to study the flow pattern around submarine pipeline spans, and predict the amplitude and frequency of the vortex induced vibrations. The sensitivity of the computational fluid ...
