Exploring wave propagation behaviors in rock: A grain‐based perspective on mineral structures
Deep Underground Science and Engineering, EarlyView.This study investigates wave propagation in rock at the grain scale using a grain‐based model, revealing that mineral elastic modulus significantly influences wave attenuation while grain size and distribution have limited effects. A novel peak particle velocity attenuation prediction model is proposed and validated for grain‐scale wave propagation ...

Deep Underground Science and Engineering, EarlyView.Our study reveals that caving‐enhanced geothermal systems (C‐EGS) with adequately fractured reservoirs achieve optimal heat extraction by minimizing preferential flow paths, while conventional fracturing (F‐EGS) and pipe‐based (P‐EGS) systems suffer accelerated thermal drawdown.

Rock typing in geothermal reservoirs: application of textural descriptors
, 2016 Geothermal energy is a key in the transition to 90% renewable electricity production by 2025, which is a target set by New Zealand government. 22% of the current national electricity generation comes from geothermal resources and it is expected to keep ...

Techno-economic assessment of the horizontal geothermal heat pump systems: A comprehensive review [PDF]
, 2019 Geothermal heat pump has been widely recognized as one of the promising technologies for building applications because of its high energy efficiency and low operating expense, however the high capital investment and installation costs discourage building

Deep Underground Science and Engineering, EarlyView.The evolution of the temperature field and frozen wall under different fracture conditions was examined by an artificial ground freezing‐based thermal‐hydraulic coupled model. It was observed that fracture inclination affects the interaction extent of freezing pipes and fracture, while phase transition extent is the dominant factor for heat transfer in

Development of the MultiGAS for determining fumarole gas chemistry in geothermal systems
, 2013 Geothermal exploration relies in part on the gas geochemis- try of fumaroles, bubbling springs and steaming ground to offer insight into the nature of the fluids at depth, processes affecting them when rising to the surface, and provide estimates of the ...
