In this paper we study the thermal performance of a 5 kW rectifier module experimentally and numerically, with the aim of changing the cooling methodology from an active cooled (fan cooled) to a passively cooled system. ...

Herein we present the design of infrared mirror coatings for the enhanced performance of incandescent lighting. We consider single and stacked dielectric mirrors comprised of alternating layers of TCO and SiO2 nanoparticle ...

A two-dimensional analytical heat conduction model of an annular composite fin has been carried out. The composite fins composed of a porous polyethylene core, a square aluminum insert, and metallic zinc coating layers, ...

With increasing energy cost and constraints on emission standards, there is a strong need to reduce energy consumption and/or increase equipment efficiency. Refrigeration systems are the third largest use of electricity ...

Phase Change Materials (PCMs) have been widely used in Latent Heat Thermal Energy Storage Systems (LHTES) to store and release thermal energy. However, PCMs suffer from their low thermal conductivities, which leads to ...

The effects of the wall temperature on the residual layer thickness of the polymers are studied numerically in the filling process in the injection molding process. A lubrication approximation model is developed to furnish ...

In the last two decades, majority of the newly developed dental caries detection techniques have been optics-based, relying either on enhancement of light scattering in early carious lesion (e.g. optical coherent tomography ...

When thin paint layers are exposed to heat, evaporation of the solvent begins, and significant movement within the paint film occur, causing temperature and concentration gradients. A clear coat paint was used, which had ...

The Ranque-Hilsch Vortex Tube (RHVT) is a small tube without any moving parts receiving compressed air from a tangential inlet and exhausting cold air from a small hole at one end of the tube while exhausting hot air from ...

The stretched laminar flame model provides a convenient approach to embed realistic chemical kinetics when simulating turbulent premixed flames. When positive-only periodic strain rates are applied to a laminar flame there ...
