Simulation models for steady state thermal hydraulics analyses of ORNL’s HFIR have been developed using COMSOL. A single fuel plate and coolant channel of each type of HFIR fuel element was modeled in three dimensions. The standard k-? turbulence model was used in simulating turbulent flow with conjugate heat transfer. The COMSOL models were developed to be fully parameterized to allow ...

The present study focuses on the design and analysis of a single-engine, propeller-driven general aviation airplane. Initial weight estimation based on the initial sketch and the design mission profile is conducted. The estimated weight and other design parameters are used to define the external geometry of the fuselage, wing and tail. Conic lofting is utilized to render a layout of the design ...

Spondylolysis (SL) is a defect of the spinal vertebra, and is typically caused by stress fracture of the pars interarticularis bone of the vertebral arch. It is especially common in adolescents who over train in sporting activities. Spina bifida occulta (SBO) is a malformation of the spine where the protruding vertebral bodies are not fully formed. In this study we demonstrate the predisposition ...
Multiphase Transport with Large Deformations Undergoing Rubbery-Glassy Phase Transition: Applications to Drying

Drying of biomaterials such as foodstuffs involves mass, momentum and energy transport along with large shrinkage of the porous material, which have significant effects on their final quality. Foodstuffs exhibit non-linearity when undergoing large deformations that affect the transport process in a critical way. Thus, it becomes important to perform a two-way coupling of the multiphase transport ...

The geometrical design and material choice for a refractory lining requires a good understanding of its thermo-mechanical behavior. Design engineers clearly need a tool for fast and efficient computation of thermo-mechanical state of refractory linings under various conditions. However, standard simulation models and their solutions suffer as the linings are composed of many refractory blocks in ...

The present work aims to develop a blood pressure sensor using MEMS/NEMS technology. A normal blood pressure detector is used externally, but this work mainly aims for designing an implantable nanotube based sensor for continuous monitoring of blood pressure. The use of COMSOL Multiphysics 4.1 acts as a good platform to develop a nano tube based sensor design by using the MEMS module. The ...

The key issues of the Fraunhofer Institute for Solar Energy Systems are research and development of solar technologies for the fast growing market of solar energy. This paper presents examples of the usage of COMSOL Multiphysics: The ingress of water is a serious reason for the degradation of photovoltaic modules which can hardly be measured using experimental approaches yet. Therefore, a ...

Structural analysis is performed to check the durability of Engine mounts for a given load and support conditions. The engine mount bracket is subjected to loads primarily due to weight of the powertrain and the unbalanced torque. In this analysis, the component is optimized such that stresses generated do not exceed the endurance strength of the material. In this paper, structural mechanics ...

The Large Hadron Collider at CERN has begun operations at 7 TeV center of mass energy. CERN plans to run at this energy until the end of 2012 with the goal of providing an integrated luminosity of a few fb?¹ to the CMS and ATLAS experiments. The LHC will then shut down for 1.5 to 2 years to make the revisions necessary to run at ~14 TeV. Operation resumes in 2014. In 2017/18, there will be ...

Bridge piers and abutments makeup the bridge substructure and transmit loads from the superstructure to the bridge foundation material (Figure 1). The bridge abutment serves three purposes: to provide vertical support to the bridge superstructure where the bridge ends, to connect the bridge with the approach roadway, and to retain roadway base materials. There are several types of abutment ...
