Special Issue Information
Dear Colleagues,
Enhancing fluid-to-wall or wall-to-fluid heat transfer is a cornerstone of engineering and physics applications. Over the course of five decades, this topic has been an active area of research, since it yields a reduction in the energy required to operate the related heat transfer devices, as well as a reduction in materials and other savings. It is also of great interest in the transition to clean energy. The efficiency of heat transfer devices can be improved by reducing thermal resistance, such as the laminar sublayer where the fluid velocity is low. To achieve this, passive and active methods are employed. Examples of passive methods include: (i) turbulence promotors of different geometry, (ii) corrugated surfaces, and (iii) the suspension of small solid particles with high thermal conductivity. Examples of active methods include: (i) stirring the fluid, (ii) surface vibration, (iii) fluid pulsation, (iv) fluid injection, and (v) fluid suction.
The aim of the present Special Issue of Fluids is to gather papers dealing with physical mechanisms leading to heat transfer enhancement in both single- and two-phase systems.

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. Fluids 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 1800 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.
