New Measurements of the Apparent Thermal Conductivity of Nanofluids and Investigation of Their Heat Transfer Capabilities

This article studied the thermal conductivity values and measurements for the following two systems using the transient hot wire (THW) and transient plane source (TPS) techniques: ethylene glycol with added CuO, TiO2, or Al2O3 nanoparticles and water with added TiO2 or Al2O3 nanoparticles or multiwall carbon nanotubes (MWCNTs). A TPS technique using a thermal conductivity analyzer ...

A combined finite-discrete element method for calculating the effective thermal conductivity of bio-aggregates based materials

This study used a two part process to create a system that would predict the thermal conductivity of insulated building materials containing plant materials. A finite-discrete element method was used to predict the thermal conductivity of a packed bed of sunflower pith, while a discrete element method was used to predict how aggregates would fill a volume element. These were used to predict the thermal conductivity of the heterogeneous volume. ...

Finite element analysis of transient thermoelastic behaviors in disk brakes

Using the transient method, the thermoelastic properties of disk brakes are studied. Specifically, frictional heat generation is studied using the finite element method. In addition to this, the investigators looked into the thermoelastic instability (TEI) phenomenon in order to modify the conceptual design of disk brakes....

Optimization and Analysis of Thermoelectric Properties of Unfilled Co1–x–yNixFeySb3 Synthesized via a Rapid Hydrothermal Procedure

A new application for the transient hot-wire technique for thermal conductivity measurements has been described. It is intended to provide an accurate means of implementation of the method to the determination of the thermal conductivity of solids exemplified by a standard reference ceramic material. Measurements of the transient temperature allows an absolute determination of the thermal conductivity of the solid. The uncertainty achieved for the thermal conductivity is better than ±1%, ...
