Thermally Affected Assessment in Groundwater Heat Pump Systems

Dear Colleagues,

we are inviting you to send contributions to a Special Issue of Energies with the title “Thermally Affected Assessment in Groundwater Heat Pump Systems”.

Over time, a large number of geothermal energy technologies have been proposed for heating and cooling needs of buildings due to their attractive advantages in energy efficiency and environmental benefits in terms of greenhouse gas emissions.

Among low-enthalpy geothermal systems, open-loop groundwater heat pumps (GWHPs) currently represent one of the major technologies. Many technological and environmental aspects have to be considered in order to optimize the performance and minimize the subsurface impact.

Among the others, particular attention must be posed on long-term sustainability of the groundwater abstraction and the development of a thermally affected zone (TAZ) around the re-injection wells.

Analytical solutions and numerical models have been widely applied in the past years to understand and predict subsurface heat transport mechanisms capable to take into account the site-specific geological conditions, the transient heat and groundwater flow regimes and the anisotropies in the subsurface media.

This special issue aims to give a comprehensive overview about the state-of-art of the research in this field contributing to the discussion about the benefits and limits in open-loop systems diffusion at a local and regional scale.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Energies is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
