Special Issue Information

Dear Colleagues,

Marine engineering dates back to the origins of human civilization. In recent centuries, the exponential growth of marine engineering and naval architecture was caused by the development of global industrial capitalism. Offshore industries and marine transport, supported by state-of-art marine and ocean engineering knowledge, are indispensable parts of modern society. Numerous state-of-art methods suitable for marine engineering have been developed in recent decades, and complex fluid-structure theoretical and computational models have been created to ensure synergy between the fundamental sciences (e.g., mathematics, physics, hydrodynamics, and chemistry) and engineering.      

The scope of this Special Issue includes but is not limited to, the safety and reliability of naval architecture, as well as the dynamic stability of marine transport energy-efficient logistics. We hope to collate innovative research studies on engineering and mathematics, physics, hydrodynamics, reliability and statistics, control, logistics, and stability theories. Green energy and CO2 reduction technologies are especially 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 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. Journal of Marine Science and Engineering 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.

By combining computational fluid dynamics (CFD) and surrogate model method (SMM), the relationship between turbine performance and airfoil shape and flow characteristics at low flow rate is revealed. In this paper, the flow velocity tidal energy airfoil model is designed based on the Kriging model, and the original airfoil with a relative thickness of 12% and a relative curvature of 2.5% is obtained. The parameter optimization is carried out by setting the 4th CST equations through the surrogate model; the maximum lift-drag ratio is the optimization goal, the optimization design variable is 10, the maximum number of iterations is 100, and the maximum number of sub-optimization iterations is 200. The results show that the hydrodynamic performance of the airfoil with thinner thickness and more curvature is better, the maximum thickness part is shifted forward by 4.58%, and the lift-drag ratio is improved by 4.03%. The flow field and the efficiency are more stable, which provides an engineering reference for the optimal design of hydraulic turbine airfoils under low flow velocity. It supplements the research on the performance of turbine blades in low velocity. Full article
