The Eustachian Tube (ET) is a collapsible tube that connects the middle ear to the nasopharynx. Dysfunction in the ET leads to a disease called Otitis Media. Our goal is to develop and use fluid-structure interaction (FSI) models of ET opening phenomena to better understand what factors ... Read More
Passive, one-way valves, also known as check valves, while common at the macro scale, are an essential microfluidic feature that facilitate flow rectification. These structures are also commonly used in reciprocating micropump configurations to control flow. Their operation can be ... Read More
Finite element method (FEM)-based solutions are known to contains errors and uncertainties due to at least four mathematical (M) and four physical (P) sources, namely, (M-1) mesh density or degrees of freedom, (M-2) mesh element types, (M-3) mesh quality such as mean aspect ratio, (M-4) ...

This assignment deals with the modeling of a pressure controlled current-limiting valve. For this purpose the CAE-Software COMSOL Multiphysics® is used. Current-limiting valves are used as a measure of safety in many hydraulic applications. They are deployed in cases of a high decrease ... Read More
Fluid-structure interaction (FSI) refers to a class of problems in which the motions of fluid and solid are coupled. FSI is of great significance in many applications such as aero-elasticity, biomechanics, and design of various engineering systems. Typically, the multiphysics involved in ... Read More
The assessment of the seismic safety of gravity dams is a topic of great importance in civil engineering. In this paper, fluid structure interaction modeling of gravity dams during earthquakes is investigated. In particular, this work aims to provide physical significance of a plan ... Read More
Large centrifugal compressors, which are commonly applied in the oil and gas and in the process industry, may fail due to vibrations of the impeller. These vibrations are induced by pressure pulsations in a compressor stage. These vibrations can be especially strong in so-called dense ... Read More
This paper presents a hybrid finite element – finite volume algorithm for solving multi-scale fluid-structure interaction during transient operation of a hydraulic rod seal. The elasto-hydrodynamic model consists of several micro-scale and macro-scale analyses types, all incorporated in ... Read More
The Finite Element Model is analyzed with impounded water considering appropriate boundary conditions between the water & the upstream face of the dam .The fluid on the upstream side is considered to be incompressible, inviscous, and irrotational. Here the effect of fluid ... Read More
Air bearings are special type of bearings which provide nearly zero friction between two surfaces. This is achieved by a compressed layer of gas between the surfaces. This study presents a modeling technique for an Air bearing component. COMSOL Multiphysics® is used to efficiently ... Read More
