Radioactive waste disposal, as the final step of open nuclear fuel cycle, is an important process to protect humans and environment from harmful effects ionising radiation. Approaching construction geological repository, understanding predictability behavior engineered barrier material becomes more than ever. Therefore, a number research studies are being focused on experimental numerical analy...

Marine diesel engine is essential on a ship, but emits extremely loud noise harmful to human hearing. Therefore, it mandatory use silencers reduce the venting of marine engine. An advanced silencer with new acoustical element curved tube, along perforated holes, presented suppress wave. To predict silencer's performance for high-order waves, finite model was built using COMSOL. The influence re...

In this study, the thermal analysis of an aluminum piston coated with MgOZrO2 to create a barrier COMSOL multiphysics program and changes in exhaust gas temperature, fuel consumption, engine torque values obtained as result test experiments were examined. For purpose, uncoated was started biodiesel 5% water + 15% ethanol doped at speeds 1000 rpm, 1500 2000 2500 rpm. results COMSOL, it found tha...

PURPOSE In this work, a finite element study is proposed by using the Comsol Multiphysics software to evaluate the effects of microcrack shape, size and direction on the poroelastic behaviors of a single osteon. METHODS This finite element model is established by using the Comsol Multiphysics software, and we just focus on the comparison of the influences of those microcrack geometric paramet...

Several parameter estimation problems (or ‘‘inverse’’ problems) such as those that occur in hydrology and geophysics are solved using partial differential equation (PDE)-based models of the physical system in question. Likewise, these problems are usually underdetermined due to the lack of enough data to constrain a unique solution. In this paper, we present a framework for the solution of unde...

Home based or tele technological systems and smart devices have provided alternative delivery forms to promote hand rehabilitation. As a step towards the targeted system, a finite element method (FEM) simulation based on MGC3130 three-layer electrode design in Comsol®, and a nonlinear regression analysis using Matlab® were carried out. Concerning different combinations of fingers’ movement and ...

Red Blood Cell (RBC) suspended in aquatic buffer is trapped and deformed by the dual-beam optical tweezers in order to measure the elasticity of the cell’s membrane. In this experiment, the RBCs were in the natural form of biconcave disc shape. We modeled a highly focused trapping beam of numerical aperture NA=1.25 as a spherical wave with Gaussian intensity distribution in a stationary study m...
