1. Flow-induced uvula deformation considerably altered the flow dynamics inside the nose. 2. For a weak soft palate, complete flow occlusion can occur (sleep apnea). 3. Vibration of the airway structures is crucial to better understand snoring generation mechanisms and breathing-related disorders.

Microwave drying of foodstuffs is a complex interplay of mass, momentum, and energy transport coupled with large deformation of the solid. To be able to better understand the microwave drying process, a fundamentals-based three dimensional (3D) multiphase porous media based model is developed to simulate the microwave drying process. An elaborate experimental system comprising of infrared ...

Nuclear Quadrupole Resonance (RQN) is a radio frequency (RF) spectroscopic technique that is used to detect quadrupole nuclei such as Nitrogen-14. NQR was found to be a good candidate for detecting narcotics, explosives and medicines . However, due to its low sensitivity the use of NQR is still limited. One way to increase the sensitivity is to improve the RF coil by means of a better RF ...

A Polysilicon H-beam is a micro-machined structure consisting of two primary members connected by a third member of much lower width and much greater aspect ratio. This structure exhibits interesting vibration behavior at specific frequencies which are known as resonant modes. A ‘mode’ may be described as a specific physical shape that the vibrating object assumes at peak oscillation amplitude ...

Silicon wafers represent key elements in modern microelectronics or photovoltaics. Technological fabrications of wafer sizes with large diameters (e.g. 450 mm) allow an efficient realization for integrated circuits at low cost. However, this material shows a high sensitivity to vibrations that strongly depends on size and the positioning as well as orientation of a wafer in a mounting, realized ...

The subsurface thermal regime has been investigated in boreholes from southern Norway. During the purely conductive 2D thermal modeling, the COMSOL Heat Transfer for Solids interface has been used to simulate heat transfer by heat conduction. COMSOL physics interfaces Heat Transfer in Porous Media and Porous Media and Subsurface Flow/Darcy's Law have been used to carry out a fully coupled ...

Radioactive waste repositories include barriers that work to contain the waste, thereby protecting human health and the environment. In deep geological disposal systems, barriers include the natural geological barrier and the engineered barrier system (EBS). The ability of the EBS to limit groundwater flow is important and optimized design solutions are often sought by means of numerical ...

In inductive heating simulations the electromagnetic properties of the steel have a significant impact on the temperature pattern along the heated product. Indeed, taking into account the non-linearity of the ferromagnetic material properties is a key point to have relevant simulation results. In particular, it is important to correctly include the nonlinear relationship between the magnetic ...

Nano patterning for chip manufacturing has reached its limitation with 193i lithography standard process. Directed Self Assembly (DSA) of Block Co-Polymers (BCP) is envisaged as an alternative complementary technique that can reduce critical dimension and pitch with high throughput and limited cost . For contact layers that require patterning of cylinders with diameter of tens nanometers, DSA ...
