Determining the thermal conductivity of liquids. Part II: Establishing an accurate and repeatable experimental methodology

The authors state that the TPS technique isn't an accurate method for the measurement of thermal conductivity, thermal diffusivity and volumetric heat capacity of liquids. This is due to the effects of natural convection caused by the sensor which introduce a significant error in the measurements. Six commonly known liquids were investigated using the TPS technique and the obtained values were compared to literature and were found to be significantly ...

Determining the thermal conductivity of liquids using the transient plane source method. Part I: Establishing transient thermal-fluid constraints

The authors look into problems with accurately measuring thermal conductivity of liquid samples. Among these problems is the onset of natural convection during the measurement of thermal properties, which may lead to skewed values reported after characterization. The effect of natural convection is analyzed numerically for the transient plane source method in order to determine at what time during an analysis the convection causes incorrect output data. The effect of ...

Study of coupled transient radiation-natural convection heat transfer across rectangular cavities in the vicinity of low emissivity thin films for innovative building envelope applications

As buildings are constructed, pores and cavities are formed within the building envelope and can cause issues with coupled transient radiation-natural convection heat transfer. This research aims to develop a model to minimize the empty space in the area lining the exterior and interior of the building (building envelope). As cavities and pores are present within the building envelope, issues of heat loss and high energy consumptions arise. An improved ...
