Special Issue Information
Dear Colleagues,
Flow control technologies are usually employed to modify flow forces acting on bluff bodies. Traditionally, passive flow control devices (where no injection/suction of flow is required) were used, but the tendency nowadays is to interact with the boundary layer using active flow control technologies, mostly because they do not impose any drag penalties in off-design conditions. In this regard, synthetic jets, fluidic oscillators and plasma actuators appear to be particularly efficient since they are capable of generating a pulsating flow, and as a result, the boundary layer can be activated using particularly low levels of energy. In this Special Issue, any scientific research work related to passive and active flow control applications are very welcome, and research considering the design and performance of different actuators will also be accepted. Both experimental work and computational simulations fall into the scope of this Special Issue; moreover, applications considering optimization techniques capable of obtaining optimum parameters will be highly regarded, since they greatly help in minimizing the number of computational simulations while gathering the most appropriate set of active flow control parameters in any given application. Finally, papers considering the application of flow control technology employed to enhance heat transfer on any surface or used to reduce cavitation in water turbines, for example, will also fall into the scope of the present Special Issue.
As a conclusion, it can be stated that any novel research work considering flow control applications to any bluff body is entitled to be published in the present issue.

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. Applied Sciences 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 2400 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.
