Permanent magnets are ubiquitous in our world today, from refrigerator magnets to industrial sensor applications. Often, the magnitude of the field at a specific distance from an arbitrarily shaped magnet of variable strength is a necessary parameter for end-use systems. We used the the ... En savoir plus
Radio frequency (RF) micro-electro mechanical system (MEMS) switch works in on/off modes controlled by electrostatic forces. In off mode, rough surfaces of electrodes come into a contact. Membrane contact surfaces have complex surface roughness patterns and the mechanical contact problem ... En savoir plus
A 2nd-generation irradiation target holder is being developed at the High Flux Isotope Reactor (HFIR) of Oak Ridge National Laboratory (ORNL). This 2nd-generation holder design is focused on improving the loading and unloading of the targets by the HFIR operators since a large number of ... En savoir plus
Eccentricity in annular channels contributes to changes in fluid flow characteristics which in turn, affects the performance and integrity of the configuration. This research investigates a model of an annular channel with a diameter ratio of 0.762, an aspect ratio of 68.9:1 and heating ... En savoir plus
Plate fin-tube heat exchangers are used extensively in heating, ventilating, and air conditioning, process engineering, and refrigeration systems. They have a high degree of surface compactness. Substantial heat transfer enhancement is obtained as a result of the periodic starting and ... En savoir plus
The liquid food product packaging are today predominantly made with board LPB type board (Liquid Packaging Board) composite formed by board, which offers mechanical strength, polyethylene, constituent responsible for protection against the passage humidity, and aluminum foil, which helps ...

Recent studies report problems related to premature aging and degradation of high-voltage polymeric insulators. Corona activity, which is induced in areas of high electric field levels, is considered one of the leading causes of these problems. The insulator operation under adverse ... En savoir plus
The direction of the fluid is strongly related to the Reynolds number; as it increases, so does the centrifugal acceleration which tends to push the axial flow towards the outer side of the pipe. Secondary flow appear as 2 or 4 vortical structures after the inflection point. For low ... En savoir plus
A simulation of an electrodynamic planar loudspeaker (EDPL) has been developed in this study with the COMSOL Multiphysics® software. Using the simulated model, effect of different parts has been studied to improve the performance. The locations of the coil and magnets have been obtained ... En savoir plus
At Oak Ridge National Laboratory (ORNL), COMSOL Multiphysics® software has become a preferred software for certain multiphysics applications in nuclear engineering. This presentation will highlight some of the ongoing activities in the following areas: (1) Highly enriched uranium (HEU) ... En savoir plus
