Numerical Simulation of Nanofluid Suspensions in a Geothermal Heat Exchanger

Energies, 2018
It has been shown that using nanofluids as heat carrier fluids enhances the conductive and convective heat transfer of geothermal heat exchangers. In this paper, we study the stability of nanofluids in a geothermal exchanger by numerically simulating ...

Simulation of an absorption based solar cooling facility using a geothermal sink for heat rejection [PDF]

, 2008
An important issue of solar cooling facilities based on absorption cycles and sometimes not given the necessary attention is the recooling process of the absorber and condenser.

Numerical analysis of thermal cycling during a multi-stage energy pile thermal response test [PDF]

, 2016
Energy piles are emerging as convenient alternative to the more traditional borehole heat exchangers (BHEs) to provide heating/cooling to buildings, as they remove the need for special purpose excavations and can accommodate more pipes, thus enhancing ...

Ecological Processes Underpinning Microbial Variability in Archean Granitoids Beneath the Deccan Traps: Evidence From Deep Drilling in Koyna, India

Environmental Microbiology Reports, Volume 18, Issue 3, June 2026.
Deep biosphere hosted by Archean granitoid basement of Deccan Traps showed depth‐wise microbial partitioning. Limited dispersion and variable selection control community assembly. Fewer abundant bacterial taxa were ubiquitous, while large numbers of rare taxa remained localized.

Formation of thermal fields by the energy-chemical complex of coal gasification [PDF]

, 2017
Purpose. The objective is to generate thermal energy from basic segments of the energy-chemical complex formed on the basis of borehole underground coal gasification with determination of its operation modes. Methodology. The set engineering tasks were

Fault‐Mediated Groundwater‐Surface Water Mixing Amplifies Hydrochemical/Hydrological Dynamics in a Semi‐Arid Volcanic Lake Basin

Hydrological Processes, Volume 40, Issue 5, May 2026.
Isotopes data help to understand the GW‐SW connectivity, the recharge elevations, and evaporation in a volcanic lake basin. ABSTRACT Understanding groundwater (GW) to surface water (SW) connectivity (i.e., the exchange of water and solutes between aquifers and surface bodies) is increasingly important under changing climate conditions, where ...

Solar and geothermal energy for low-carbon space heating and energy independence. [PDF]

, 2019
In developed countries, space heating is highly dependent on fossil fuels consumption. Also, the non-renewable fuels combustion emits CO2 which is claimed to impact the most on greenhouse effect.

Stemflows and Preferential Flows: A Historical Review and Challenges for the Future

Hydrological Processes, Volume 40, Issue 5, May 2026.
Possible implementation of stemflow in the MIPS model where all water in the system is represented as particles in pathways of specified velocity. Stemflow (green particles) can be treated as a localised input with probabilities of entering higher velocity pathways than throughfall, depending on the input rates.

Revealing Permafrost Continuity Across a Northern Watershed With Airborne Electromagnetics

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 5, May 2026.
Abstract Permafrost thawing in northern regions may alter groundwater‐surface water dynamics, thereby impacting hydrologic and ecologic functions and the potential release of stored solutes including carbon. Here, we present an airborne frequency‐domain electromagnetic survey over a discontinuous permafrost region within the Central Mackenzie Valley in

Asymptotic analysis of vertical geothermal boreholes in the limit of slowly varyng heat injection rates [PDF]

, 2014
Theoretical models for the thermal response of vertical geothermal boreholes often assume that the characteristic time of variation of the heat injection rate is much larger than the characteristic diffusion time across the borehole.
