In this contribution we present the results of the numerical modeling and performance optimization study of a diaphragm pump for drug infusion. The main objective is to develop a numerical model that replicates the pumping cycle (400ms) and also provides indications about the variation of pumping performance as consequence of the variation of the chamber-diaphragm system geometry, diaphragm ...

Linear wave propagation through inhomogeneous structures of size R?? (Fig.1) is a computationally challenging problem, in particular when using finite element methods, due to the steep increase of the number of degrees of freedom as a function of R/?. Fortunately, when the geometry of the problem possesses symmetries, one may choose an appropriate basis in which the stiffness matrix of the ...

Micro-tubular Solid Oxide Fuel Cells (mSOFC) are attracting more and more interest as new generation of energy conversion devices. Although commercial applications still suffer from high costs, there is a need for further improvement of the cell performance, durability and start-up. To resolve those challenges, knowledge of the distributions of species concentration, temperature and current ...

One of the methods to recover oil from medium and low viscosity in complex reservoirs uses air injection leading to oil combustion. In this case the oxygen in the air burns the heavier components of the oil, generating a heat wave leading to vaporization of lighter components. The combustion mechanisms are different for light oils, where evaporation is dominant, whereas for medium non-volatile ...
Virtual Prototype Evolution by COMSOL Multiphysics® of a Continuous Flow Animal By-Products ABP Ohmic Sterilization Unit - new
C-Tech Innovation Ltd., Capenhurst, Cheshire, UK
Ohmic heating (Joule heating) is a volumetric heating technology which can effectively process almost any pumpable fluid with extremely high energy efficiency (>95%). This is particularly useful for very thick fluids, those that burn on to hot surfaces and those with high solids content which would cause difficulties for conventional heating techniques. Processing of animal by-products (ABP) ...

In this work, a bimetallic strip based thermal sensor was designed using MEMS module of COMSOL Multiphysics® software to monitor the temperature rise in insulating oil which was used as coolant in transformers. The bimetallic strip was designed with different shapes such as cylindrical, rectangle, square & conical and different compositions such as Al/Steel Alloy and Fe/Cu which can withstand ...

Electron beam has a wide range of applications in the material processing and joining techniques. Apart from that, it has also been utilized to simulate steady as well as transient fusion reactor relevant heat loads. Transient heat load events spontaneously occur in the fusion reactor. Several hundred megawatt of power is dumped upon the plasma facing material surfaces for a very short ...

Introduction: Lithium-ion batteries are widely used as power sources for portable electronic devices (laptop, phones, and players) and electric cars due to their high energy density. New applications, such as Formula E, require also a huge power capability that the iron-phosphate-based positive electrode is able to provide. Indeed, a recent publication  shows that, at the particle level (20 ...

In this paper simulation and parametric study of a PDMS valveless micropump using Fluid-Structure Interaction (FSI) appraoch is presented. The simulation for the valveless micropump were carried out in COMSOL Multiphysics software. In case of a valveless micropump diffuser/nozzle element is connected to a chamber with an oscillating diaphragm. To improve the flow rate of the valveless micropump, ...
