Entropy Generation in Nanofluid Flows II

Dear Colleagues,

Recent advances in nanotechnology have allowed the development of a new category of fluids named nanofluids. Using nanofluids is a promising method to achieve a higher heat transfer rate in different thermal systems such as heat exchangers. Nanofluid also can be used to develop better oils and lubricants in real applications. In addition, nanofluids can be employed in solar energy systems to enhance the efficiency of these systems and have some applications in medical process such as cancer therapy and safer surgery by heat treatment. Many researches are performed on the thermophysical characteristics of nanofluids and their applications in thermal systems, since 1995.

The entropy generation or second law analysis is a good method for evaluating a thermal system as the first law only deals with conservation of energy and does not discuss about possibility of destruction of the useful work during a heat transfer process. This analysis can be employed for the design, optimization, and yield assessment of different thermal devices. The first studies on entropy generation due to nanofluid flow have started from 2010. The aim of this Special Issue is to encourage the researchers to present their latest original researches on entropy generation and exergy analysis for nanofluid thermal systems. Both experimental and numerical methods can be used to perform an entropy generation analysis for these systems. Entropy generation analyses for Newtonian and Non-Newtonian nanofluid flows in simple or complex geometries with different sizes (e.g. micro to conventional) are welcome. Entropy generation analysis for different applications of nanofluids including renewable energy devices, heat exchangers, and medical processes can be considered for review process.

Existing literature indicates that the studies on these topics are still scant. In order to fill this gap, researchers are invited to contribute their original research and review papers in these topics.

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.
