Bioresorbable stents are providing temporary mechanical support to keep a narrowed or blocked coronary artery open and restore the blood flow and will be gradually degraded and resorbed after the healing and remodeling of arterial wall. This new generation of stents has lower rates of restenosis and in-stent thrombosis in comparison with permanently bare-metal stents. Since this new generation ...

The process of cold drawing a fiber over rollers is analyzed in this work to predict the temperature rise due to the heat generated during plastic deformation of the fiber. Experimental measurements on prototypes indicated an unacceptable temperature rise of greater than 100 F requiring identification of process modifications to reduce the temperature rise to an acceptable level. A ...

This work demonstrated the importance and feasibility of experimental image to simulation workflow. The workflow is successfully applied to a food processing study, where multiphysics and multiscale modeling based on 3D experimental image reconstruction contributes to the preservation of corn, one of the major food sources for the world population.

There is considerable interest in the possibility of combining NTE materials with normal (positive) thermal expansion materials, to reduce the potential of failure of a material or component due to thermal stress fracture. Finite element analysis (FEM) is used to explore the overall expansion and thermal stress in composites.

A contactless electromagnetic principle for the excitation of mechanical vibrations in resonant structures has been investigated. The principle relies on no specific magnetic property of the resonator except electrical conductivity and can be adopted for employing the structures as resonant sensors for measurements either in environments not compliant with the requirements of active electronics ...

Advances in visualization and discretization of pore structures by means of Computed Tomography, and rapidly increasing computational capabilities, allow numerical modeling of pore-scale fluid flow based on the incompressible Navier-Stokes equations rather than using a macroscopic approach based on Darcy’s law. To test the capabilities of the COMSOL Multiphysics modeling platform, we ...

High intensity discharge lamps can experience flickering and even destruction, when operated at high frequency alternating current. The cause of these problems has been identified as acoustic resonances inside the lamp’s are tube. Here, a finite element approach for the calculation of the acoustic response function is described. The developed model does not include the plasma dynamics.

The purpose of this paper is to illustrate the microwave coagulation therapy (MCT) that can be used mainly for the treatment of hepatocellular carcinoma. In this treatment invasive technique are used in which thin microwave coaxial antenna is inserted into the tumor and the microwave energy heats up the tumor to produce the coagulated region including the cancer cells. We have to heat the ...

The concept of virtual prototyping can be found linked to many different keywords in the literature: modeling, look-ahead problem solving, etc. This poster paper briefly discusses the potential real benefits that can be realized through pre-build cost savings, minimization of the number of prototype builds, and post-build problem avoidance for physical prototypes and production products. ...
Near-Wellbore Physics of Non-Isothermal Flow Into a Wellbore and its Application to Hydrocarbon Production
John Lovell received a Ph.D. in Electrical Engineering from Delft University in 1993 as well as MA\'s in Mathematics from Oxford and Cornell. He is currently a Business Development Manager for Schlumberger. His numerical expertise includes the creation and application of finite element algorithms for problems relating to the near-wellbore physics of hydrocarbon production from subterranean ...
