Soft lossy viscoelastic polymers can dissipate significant amounts of energy in the form of heat when subjected to dynamic mechanical stimuli. As a result, structures comprised of such lossy materials may heat up considerably when excited by loads at a frequency that approaches one of ... En savoir plus
Thermal ablation driven by an acoustic heat source has tremendous potential for the treatment of diseased tissue. In many applications, such as treating tumors in the liver, bulk removal of tissue is required, and thermal ablation can reliably cause necrosis for a relatively large tissue ... En savoir plus
During the biopharmaceutical manufacturing process, proteins stored in aqueous solutions are frozen and thawed. Frozen aqueous solutions provide an excellent medium for storing and transporting the protein without degradation. In this work, the freezing and thawing of an aqueous solution ... En savoir plus
Radial fins are widely used in industrial applications to enhance heat transfer. Exact solutions are available for radial fins of simple profiles such as rectangular, concave and convex parabolic, hyperbolic and triangular. However, such solutions may be cumbersome for use in everyday ... En savoir plus
Our group developed an experimental millimetric capsule intended to release chemicals or drugs. The delivery mechanism of such device relies on the thermal expansion of carbon-elastomer composites which deform upon irradiation of light supplied by a Laser diode through an optical fiber. ...

Energetic materials that can readily burn are used throughout both private and government industries in manufacturing of, among other things, small arms ammunition and rockets. Collections of that material when ignited can pose a risk of burns for people in the immediate vicinity. The ... En savoir plus
COMSOL® has been used to compare 2D and 3D model results to quantify what simplifications can be made when modeling thermal bridges. Currently there are suggestions put forward as to when it is appropriate to use 2D vs 3D models to capture the effects of thermal bridges. It is known ... En savoir plus
In this study, the proficiency of an external and internally cooled hydride bed was tested. This was conducted using COMSOL Multiphysics® environment utilizing the Heat Transfer Module. This was combined with a custom chemisorption model based on Lototskyy’s Metal hydride isotherm model. ... En savoir plus
Binder jet printing (BJP) is one of the additive manufacturing methods that are being widely implemented as an efficient alternative for casting and machining in the automotive industry. Sintering densification of the as-printed part (green part) adds uncertainty and possible undesirable ... En savoir plus
Metal Additive Manufacturing (AM) can be used to create topologically complex designs that would otherwise be difficult or impossible to produce using traditional methods. However, non-destructive inspection and testing of these structures is made difficult by the presence of internal or ... En savoir plus
