Determination of ground thermal properties for energy piles by thermal response tests
Environmental Earth Sciences, 2018Thermal properties of ground heat exchanger (GHE) such as effective thermal conductivity and borehole thermal resistance are commonly measured in the field by thermal response tests (TRTs). TRT has been proved to be a consolidated method to determine thermal properties of traditional borehole heat exchangers (BHEs). However, there is still lack of data

Diurnal variation in response to thermal stimulation: Mouse-hotplate test
Physiology & Behavior, 1977Abstract Circadian changes in pain thresholds were assessed in 70-day-old CF1 male mice. The hotplate method was used. A different group of 15 mice was tested every 3 hr over a 48 hr interval. Response latencies were found to vary in a sinusoidal manner over a 24 hr interval.

Thermal response test by improved test rig with heating or cooling soil
Transactions of Tianjin University, 2014An improved test rig providing both the heat and cold source was used to perform thermal response test (TRT), and the line source model was used for data analysis. The principle of determining the temperature difference between the inlet and outlet of test well can keep the heating or cooling rate constant, along with a reduced size of test rig.

Testing Transmission Lubricants: The Importance of Thermal Response
Proceedings of the Institution of Mechanical Engineers, Part G: Journal of Aerospace Engineering, 1991The performance of transmission systems, especially those of high criticality and specific torque capacity such as those in helicopters, depends strongly on lubricant behaviour. However, economic load capacity evaluation of lubricants involves the correlation of test results obtained from simple tests in order to predict service performance, which is

Numerical evaluation of the Ground Response to a Thermal Response Test experiment
2013A prerequisite for the correct design of vertical ground heat exchangers (or Borehole Heat Exchangers, BHE) for heat pump applications is the knowledge of the ground thermal properties, in particular the thermal conductivity. The Thermal Response Test is a well known experimental procedure that allows the ground thermal and the BHE thermal resistance ...
