Oscillatory Thermal Response Test (OTRT) – An Advanced Method for Gaining Thermal Properties of the Subsurface
Georg-August-Universität Göttingen, Göttingen, Germany
Thermal Response Tests (TRTs) are the state-of-the-art method to obtain the thermal conductivity of the subsurface in the nearby ambience of a borehole heat exchanger (BHE). The results of TRTs are used to determine the necessary depth of the borehole and to make long time predictions about the potential of heat extraction. For a TRT, a constant heat load is injected into the subsurface and the ...

Chocolate is a pleasurable product largely consumed over the world. It is known that ingredients, process and particle size distribution largely impact the chocolate sensory perceptions. It was hypothesized that a suitable choice of chocolate size and geometry modifies in-mouth melting and aroma release and modulates flavour and oral texture perception. Since in-vivo experiments on chocolate ...

Vehicles with battery as energy storage fascinate more and more people. Meanwhile, more questions are surfaced – How to ensure a safe operation of the battery package? How long could the cycle life of a battery package reach? Can a battery package be operated in any environmental circumstance? All these questions are the driving forces of our work – development of the optimal battery packs for ...

Bread baking is a complex process where various physiochemical and biological transformations take place simultaneously. A two dimensional model was developed for the bread baking process taking into account of volume expansion, heat and mass transfer processes. Phase change and evaporation-condensation mechanism were incorporated by defining thermo-physical properties of bread as a function of ...

A field of connected boreholes can be used both for cooling, heating and storage purposes. The boreholes transfer heat to or from the ground, which over time changes the temperature in the ground. It is important that the borehole field is properly sized and evaluated before the construction. This study presents results from borehole field evaluations of inclined boreholes used for cooling ...

Internal combustion engine components have been a main research interest over many decades. The structural mechanics and dynamics of the piston rings has been a large focus of work in order to gain a greater understanding of the how the piston ring dynamics affect the piston ring. Piston rings are often coated to reduce the level of wear on the ring as they will suffer substantial levels of ...

The application of pulsed electric fields (PEF) is well known in the food industry as an advanced technology for mass transfer improvement. A new potential adaptation area of PEF could be extracting a valuable antioxidant called polyphenol from wet olive pomace (WOP) which is a by-product of olive oil production. The modelling includes the PEF effects on the WOP which is flowing through a ...

Radio frequency (RF) heating have potential as alternatives to chemical fumigation for disinfesting legumes. This study was conducted to investigate the feasibility of RF selective heating of insect larvae in 3 kg soybeans packed in a rectangular plastic container using a 6 kW, 27.12 MHz RF heating system. A finite element based computer simulation program-COMSOL Multiphysics® was used to solve ...

Imaging Infrared Spectrometer (IIRS) is a Hyperspectral optical imaging instrument which measures the spectra of a scene in high resolution within spectral bands covering Near Infrared (NIR) to Mid Infrared (MIR) regions. Radiation entering the spectrometer assembly governs the temperature of different internal parts and hence plays an important role in determining the desired spectral ...
