Nature inspired innovation powered many engineering innovation. For example, Bird inspired flight helped us to develop intercontinental flying long range aircraft with efficiency as comparable to transcontinental migratory birds. But, short range air travel, efficiency is much lower than ... Read More
Atherosclerotic lesions preferentially develop in certain regions like bifurcations, branches, and bends [1, 2]. A possible explanation for such a preferential localization of atherosclerosis is that the geometry of the vessel influences the blood flow pattern. It suggests that the ... Read More
INTRODUCTION Our group at ORNL started using COMSOL Multiphysics® software shortly after version 3.0 was released in the Spring of 2004. After 11 years and several releases, the application usage has grown along with number of licenses we are responsible for. This paper will broaden ... Read More
With increasing awareness of coronary diseases, much research has been put into the effectiveness and benefits a coronary stent can bring to a patient with a diseased coronary artery. However, current research does not fully address the effects of restenosis on the vessel, given that it ... Read More
The high speed gas turbine is a power plant developed for modern aircrafts. It is widely used and developed because it can meet the high power to weight ratio. The rotor system of modern small gas turbine works above the critical speeds. Hence, there is a stricter requirement for the ... Read More
In this paper, the effect of a crack to the flow-induced vibration characteristics of supported pipes is investigated based on vibration method. In order to estimate the crack location and depth in the pipe, we need to utilize the variation of the difference between the natural ... Read More
This work is aimed to demonstrate how variation of geometries' parameters would affect the fluid loading effect in water using COMSOL Multiphysics and compared with analytical data. When a structure is placed in water, the interaction between the water and the structure plays an ... Read More
Pumping liquids at small scales is challenging because of the principle of reversibility: in a viscous regime, the flow streamlines through a fixed geometry are the same regardless of flow direction. Recently we developed a class of microfluidic pump designs based on tilted flexible ... Read More

ALE-methods are frequently used to solve systems of partial differential equations (PDEs) on moving domains. The main idea of these methods is to incorporate the time evolution of the domain into the equations. However, the motion of the domain with respect to time induces convective ... Read More
