Internal combustion engine components have been a main research interest over many decades. The structural mechanics and dynamics of the piston rings has been a large focus of work in order to gain a greater understanding of the how the piston ring dynamics affect the piston ring. Piston rings are often coated to reduce the level of wear on the ring as they will suffer substantial levels of ...

A 3D thermo-mechanical simulation was developed using COMSOL Multiphysics software in order to predict distortion of a welded dissimilar titanium alloys structure. An angular distortion and a longitudinal shrinkage are predicted in agreement with those obtained experimentally.

Spring-supported thrust bearings are used in huge rotor dynamic machines, generally to support the shafts from the biggest hydropower generators. Any attempt of modifying yhis type of thrust bearing implies huge investment and is associated with some risks. The goal of the present work is to predict the performance of spring-supported thrust bearings. With the model it is possible to carry out ...

Puffing of biomaterials involves mass, momentum and energy transport along with large volumetric expansion of the material. Development of physics-based models that can describe heat and moisture transport, rapid evaporation and large deformations can help understand the puffing process. In this context, a fundamentals based study of salt-assisted puffing of rice is described. A multiphase model ...

A medical ventilator is an imperative device used to save life by delivering an assortment of air and oxygen into and out of the patients’ lungs to administer breathing or to assist obligatory breathing. The commercially available diaphragm based pressure sensors made up of silicon measure the air and oxygen flow. The proposed work utilizes the Piezo electric material for the pressure range ...

An attempt was made, as described in this paper, to assign material properties like shear strength and modulus of elasticity randomly. In this way, the behaviour of a masonry wall with a prefabricated concrete lintel was experimentally tested and simulated using COMSOL. The paper confirms the possible use of COMSOL for modelling lintel-masonry interaction, including variation of mechanical ...

The reliability of solder joints [1,2] is one of the key factors in the determination of the reliability of the high power density electronic converters, being the solder joints both the mechanical, the electrical, and often the thermal connections between the electronic component and the board in which the component is placed. The main mechanism by which solder joints are damaged is thermal ...

The incidence of spinal cord injury (SCI) in the US is approximately 12,000 individuals annually, due to various forms of trauma and disease. Diminished flow over a prolonged period of time can cause permanent spinal damage. We constructed a 3D finite element model of the spinal cord to examine the role of compressive loading on spinal blood flow. It was found that the type of forces on the ...

This study is performed to know which central plate geometry is best suited for electrostatically actuated switch. The simulation is carried out in COMSOL Multiphysics, where user is free to model the geometry without depth knowledge about geometrical dependency of electrostatic. The study of the centrally suspended geometrical models such as circle, square and rectangle suspended by two short ...

COMSOL Multiphysics® has been used to predict the magnetic fields, eddy current, lorenz forces and stresses during a disruption for the new Advanced Outer Divertor for the Alcator C-Mod tokamak. A tokamak is used to study magnetic confinement of plasma for fusion, and a disruption occurs when the plasma decays, rapidly losing all of its current. COMSOL has been used to recreate the fields ...
