A drying chamber for dehydration purposes is simulated; we model a chamber chimney system coupled to a solar collector as the heat source. Using both, the Heat Transfer Module and CFD Module of COMSOL Multiphysics® software in a 2D geometry we simulate the velocity and temperature field ... 詳細を見る

Poroelasticity equations describe the interaction between fluid flow and solids deformation within a porous medium. Modeling of poroelasticity is coupling between elastic deformation of porous materials and Darcy’s law. Poroelasticity has numerous real world applications such as in ... 詳細を見る

Using COMSOL Multiphysics® Acoustics Module: Chondrocytes modeled attached to a plane (to mimic in vivo constraints) are shown to resonate near 5MHz. At resonance, the mechanical energy density in the nucleus is two times higher than in the cytoplasm. Impact exercise is modeled as ... 詳細を見る

3D printing as applied to the area of electronics manufacture covers a broad range of traditional printing technologies [1]. The attraction in 3D printing lies in its potential to disrupt the traditional photolithographic/subtractive manufacturing line with simpler additive processes. ... 詳細を見る

Photomechanical materials experience strains in response to light of certain wavelengths. These remotely triggered, photo-induced strains lead to large-scale deformations, presenting significant opportunities for wireless actuators and light-driven morphing structures. A large space of ... 詳細を見る

This study evaluates the effect of injector resistance on the mode shapes and complex eigenfrequencies of an injector/combustion chamber system by defining a high Mach-flow, potential flow form of the convective wave equation in the Coefficient Form PDE Mathematics interface. Background ... 詳細を見る

Human body communications (HBC) uses the human body as a transmission medium to connect sensors and actuators in, on or in close proximity to the human body. The HBC approach offers tremendous potential for the design and implementation of emerging personalized healthcare systems, as ... 詳細を見る

Solar drying is a ubiquitous method that has been adopted for many years as a food preservation method. Most of the published articles in the literature provide insight on the performance of solar dryers in service but little information on the dryer construction material selection ... 詳細を見る

In the context of increasing demographic pressures around the world, soil improvement techniques constitute viable alternatives to expensive foundations. Among these techniques, the biocalcification of granular soils appears as a promising alternative relying on the formation of calcium ... 詳細を見る

Engineering design studies of the feasibility of conversion of the High Flux Isotope Reactor (HFIR) from high-enriched uranium to low-enriched uranium fuel are ongoing at ORNL as part of an effort sponsored by the U.S. Global Threat Reduction Initiative program. HFIR is a very high flux, ... 詳細を見る
