Synthesis of Nd-Fe-B/Fe hybrid micro-magnets
(Amer Inst Physics, 2019)
There is an overgrowing interest in the synthesis of high performance micro magnets due to their wide application areas in MEMS, microfluidics, and micro-robotics. In addition, they possess great potential to become a model ...
Acoustic analysis and measurements of mega yachts during construction
(Royal Institution of Naval Architects, 2019)
Noise is a critical parameter for super/mega yachts which can be verified only in the final stage of a mega yacht building project. Although there are more and more advanced methods to predict noise prior to the sea trials, ...
A DECISION-MAKING PROCESS FOR SELECTION OF BETTER SHIP MAIN DIMENSIONS WITH THE EEDI REQUIREMENT
(Society of Naval Architects and Marine Engineers, 2022)
As the main dimensions of a ship, are vital on the performance of a vessel, major improvements in performance may be achieved by selecting “better” main dimensions. This paper proposes to integrate in the design technique ...
UNCERTAINTY QUANTIFICATION OF SELF-PROPULSION ANALYSES WITH RANS-CFD AND COMPARISON WITH FULL-SCALE SHIP TRIALS
(University of Zagreb - Faculty of Mechanical Engineering and Naval Architecture, 2022)
RANS-CFD is a well-established tool with widespread use in maritime industry and research. Valuable information might be extracted from the results of such simulations in terms of ship resistance and flow field variables. ...
High performance CFD simulations of sloshing in a moving tank with SPH method
(American Institute of Physics, 2021)
The aim of this work is modeling of sway-sloshing motion in a partially filled rectangular tank while different frequency of motions are enforced. Within the study, a CFD code based on Smooth Particle Hydrodynamics (SPH) ...

(Emerald, 2021)
Purpose: This paper aims that optimization parameters depending on machining processes examine to define for the milling process of AL 6061-T6 aluminum alloy used in the aviation industry. Design/methodology/approach: The ...
An investigation into the nonlinear effects in the roll motion of 2-D bodies by SPH method
(Elsevier, 2022)
Nonlinear effects in the roll motion of a 2–D body in the free surface are investigated by utilizing the Smoothed Particle Hydrodynamics (SPH) method. The continuity and Navier–Stokes equations are solved by employing the ...
Nonlinear surface SH waves in a half-space covered by an irregular layer
(Springer, 2022)
Research on the shear horizontal (SH) waves propagating in a nonlinear elastic half-space coated with a nonlinear elastic layer having slow variation in the boundary surfaces is presented. It is assumed that both the free ...
