Entropy Generation and Heat Transfer

Dear Colleagues,

The evaluation of entropy generation has been a research issue since the foundation of Thermodynamics as a physical theory related to the analysis and performance of heat devices. As a matter of fact, the cornerstone Clausius theorem of Thermodynamics ascribed entropy generation to unavoidable irreversibilities of real processes, which do not allow heat devices to perform the quasistatic upper bound efficiency.

The aim of the evaluation of entropy generation requires the proposal of models that feature heat transfer processes, taking into account the finite size of actual devices and the finite speeds of real processes. Moreover, the eventual optimization of a suitable functional with respect to the characteristic parameters of the model, allows to obtain more realistic bounds for the performance of real heat devices.

This purpose to describe accurately efficient real-life devices has brought a great variety of models and optimization criteria according to the different nature and scales of the involved processes: from quantum, to macroscopic passing through mesoscopic levels. Then, for this Special Issue aimed to provide a panoramic view (including physics, engineering oriented papers and others) of the research carried out in this field, submissions related with modeling and optimization of real heat devices are welcome.

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 250 words) can be sent to the Editorial Office for assessment.

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. Entropy is an international peer-reviewed open access monthly 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.
