Special Issue Information

Dear Colleagues,

Fluid–structure interactions of biological systems (e.g., swimming, flying and arterial flows) have attracted considerable attention in recent years, with the aim of understanding the high aero/hydrodynamic performance of fish, insects and birds, as well as the flow physics, and applying the knowledge in bionic robotics, flyers and biomedical devices. Numerical simulation becomes more and more important in the study of biological systems, for its convenience in controlling relevant parameters and obtaining comprehensive flow details. To further explore the mechanism of biological systems, it is necessary to develop more realistic numerical models. This Special Issue seeks to highlight recent advances in the numerical simulations of fluid–structure interactions of biological systems. We welcome articles on themes including but not limited to locomotion with multi-degree freedom, locomotion in the complex flow field, body–fin (wing) interaction, active and passive mechanisms in flexible structures, fluid dynamics of microstructures on surface, flying and swimming in turbulence, collective biological locomotion and swimming and flying based on machine learning and arterial flows.

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.

The self-propelled swimming of a flexible propulsor is numerically investigated by using fluid-structure interaction simulations. A distributed active moment mimicking the muscle actuation in fish is used to drive the self-propulsion. The active moment imposed on the body of the swimmer takes the form of a traveling wave. The influences of some key parameters, such as the wavenumber, the amplitude of moment density and the Reynolds number, on the performance of straight-line swimming are explored. The influence of the ground effect on speed and efficiency is investigated through the simulation of near-wall swimming. The turning maneuver is also successfully performed by adopting a simple evolution law for the leading-edge deflection angle. The results of the present study are expected to be helpful to the design of bio-inspired autonomous underwater vehicles. Full article
