Air ducts play an important role in the energy efficiency of residential homes across the country. While transporting the conditioned air from the HVAC system to the conditioned space, 30-40% of the thermal energy can be lost due to conduction . The loss of thermal energy can reduce the HVAC efficiency to up to 18% . Air ducts can be responsible for up to 12% of the air leakage or 30% of ...

Mutually soluble-solvents can improve the ultimate recovery in conventional reservoirs. Initially, the solvent moves with the imbibing aqueous phase into the reservoir. However, upon contact with oil, diffusion occurs and the solvent is transported in the oleic phase. Through the migration of the mutually soluble component from the aqueous phase into the oleic phase, oil properties and/or rock ...

PEM Fuel Cells’ durability and performance can be increased using an ejector based hydrogen recirculation system. In this work, a CFD model has been implemented to simulate the flow within an ejector used to recirculate hydrogen in PEM Fuel Cell systems. The model has been validated experimentally and has been used to design and manufacture an ejector that will be implemented in a fuel cell test ...

One of the major challenges in biology concerns the integration of data across length and time scales into a consistent framework: how do macroscopic properties and functionalities arise from the molecular regulatory networks and how do they evolve? A deeper understanding of morphogenesis and organogenesis in particular is required to advance tissue engineering. Recent advancements in 3D ...

The formation of space charge clouds is a well known problem that affects thermionic emitters in regimes of high current emission. Although some analytical models have been presented, suitable for 1D geometries, the modeling of the problem in complex 3D structures remains a challenge due to the mutual coupling between electron trajectories and field they produce. Here we propose a model able to ...

Transformations in polymers, such as polymerisation, melting/crystallization, and phase separation/remixing, are associated with changes in both rheological and thermal properties. To permit simultaneous calorimetric and rheometric measurements, the RheoDSC was developed. The RheoDSC combines two commercial instruments, a TA Instruments Q2000 DSC and a TA Instruments AR-G2 dynamic rheometer. A ...

DEMETER is a magnetic field replicator. This system is designed to deceive anti tank mines. Numerical simulation (using COMSOL Multiphysics® software) allows to indicate DEMETER's performance in various environment and various configurations. The study of the magnetic field provide also an overview of mine-clearing tools disturbances on the field generated by DEMETER.

A 1D-axisymmetric model was built to represent the drying of a single d’Ente plum to d’Agen prune. Underlying assumptions of the model were those of Di Matteo et al. 2003. Sorption isotherms of plum come from Tsami et al, 1990 and equation structure of apparent water diffusion coefficients from Sabarez, 2001. External transfer coefficients were adjusted by direct measurements. The parameters of ...

It is well-known that metal nanoparticles (NPs) excited at the plasmon frequency not only exhibit peculiar optical properties (e.g., a peak in the extinction spectrum, an enhanced electromagnetic near-filed) but also heat up . This phenomenon is highly investigated for medical applications, but it can be exploited also for the realization of optical devices. In our study we use COMSOL ...

Parallelization of microfluidic droplet generators is one of the major challenges that droplet microfluidics has to overcome to contribute significantly towards the sustainable manufacturing of advanced materials such as nanoparticles, quantum dots, active pharmaceuticals, etc. A massive parallelization system needs to maintain consistency and uniformity across all droplet makers. To achieve ...
