Highlights from NATAS 2017

Eloisa is currently a Marie Skłodowska-Curie researcher at the Friedrich-Alexander-University of Erlangen-Nuremberg, Germany. She has a background in geology, hydrogeochemistry and environmental sciences. Main research interests concern shallow geothermal energy resources and hydro-geological topics. Her current research focuses on improving thermal efficiency of horizontal ground heat exchangers. She is also involved in dissemination and outreach activity and has a long track record of cooperation with several national and international research institutions and public bodies.

Determination of Rocks Thermal Conductivity for Shallow Geothermal Application: From Laboratory Scale to Thematic Maps Generation for Some Italian Case Studies

In shallow geothermal energy, the characterization of the thermal properties of rocks is fundamental in order to assess the ability of the ground to exchange heat for building conditioning.

In fact, the performance of Ground Source Heat Pump System (GSHP) depends on both heating/cooling building loads and site-related settings. For this reason, a reliable geological and hydrogeological characterization of the ground is required. Thermal conductivity is a key parameter to properly dimensioning low enthalpy geothermal systems by numerical modeling and a direct thermal measurement performed on representative specimens is necessary to give real data to planners, public administrations and operators involved in the geothermal sector.

Roger Blaine is a consultant in thermal analysis and regulatory affairs.  He is a retired principle scientist for TA Instruments, a supplier of thermal analysis, rheology and microcalorimetry test instruments. Dr. Blaine holds a PhD in analytical chemistry from Oregon State University and has more than 100 publications on thermal analysis applications.  Dr. Blaine is a founding member of the ASTM International Committee on Thermal Analysis and is the author of more than 60 ASTM standards. 

Reference Materials for Thermal Effusivity

Quality initiatives, such as ISO 17025, require apparatus calibration using certified and traceable reference materials. However, there are no certified reference materials for thermal effusivity. In this absence, an attempt is underway to obtain the” best available” thermal effusivity values for a series of reference materials using measurements of thermal conductivity, thermal effusivity, specific heat capacity, and density. Progress is reviewed by comparing the values obtain by two different methods. 

Sarah Ackermann, MSc, is a graduate of the University of New Brunswick and has a combined eight years of experience in materials science and thermal conductivity analysis.

Theoretical, Computational, and Experimental Validation of the Modified Transient Plane Source (MTPS) Method

The Modified Transient Plane Source (MTPS) method of thermal conductivity and thermal effusivity analysis is a method of transient thermal conductivity and thermal effusivity testing with growing popularity owing to its short test times and single-sided, interfacial configuration. Previously, work has been published detailing theoretical and experimental application of this method to thermal conductivity testing of liquids, powder uniformity, and other materials. This work expands upon the previous work. It includes details on the physical basis for the MTPS model, physical simulations to confirm fundamental assumptions about one-dimensional heat flow through test samples including foams, glasses, ceramics, and metals, and model and simulation validation with experimental data.
