The thermal model for transverse heat flow of having single filament in a unit cell is extended. In this model, we proposed that two circular filaments in a unit cell of square packing array and obtained the transverse thermal conductivity of an unidirectional material. I. Thermal Model Predicting equivalent thermal conductivity of transverse flow in unidirectional composite materials is of int...

This study is focused on the entropy production due to laminar forced convection in the entrance region of a concentric cylindrical annulus. The present hydrodynamic and temperature fields are obtained numerically. Local entropy generation distributions are obtained based on the resulting velocity and temperature fields by solving the entropy generation equation. The effect of different flow pa...

Machining accuracy reliability as a key index of CNC machine tools is seriously influenced by the geometric and thermal errors. In paper, spindle unit error modeling machining analysis method proposed. By analyzing heat generation mechanism, model was developed to describe deformation electric spindle. Based on immune algorithm (IA), power transfer coefficient were optimized, obtained finite el...

introduction : this in vitro study was designed to measure and compare the amount of temperature rise in the pulp chamber of the teeth exposed to different light curing units (lcu), which are being used for curing composite restorations. methods: the study was performed in two settings; first, an in vitro and second was mimicking an in vivo situation. in the first setup of the study, three grou...

Combined Heat and Power (CHP) involves on-site or near-site generation of electricity by using gas-fired equipment along with utilization of waste thermal energy available from the power generation process and have the potential to achieve an overall system efficiency of 80% because of the utilization of thermal energy, that would otherwise be wasted, and the reduction of transmission, distribu...

The effect of partial slip and temperature dependent fluid properties on the MHD mixed convection flow from a heated, non-linearly stretching surface in the presence of radiation and non-uniform internal heat generation/absorption is investigated. The velocity of the stretching surface was assumed to vary according to power-law form. Thermal transport is analyzed for two types of non-isothermal...

AIM The aim of this study was to evaluate the heat generation of three different types of light curing units. METHODS AND MATERIALS Temperature increases were recorded from a distance of 1 mm from a thermocouple to the tip of three different types of light curing units including one quartz-tungsten halogen (QTH), one plasma arc (PAC), and one light emitting diode (LED) unit. An experimental m...
