ABSTRACT Weapons are morphological structures used by animals in various contexts, especially in intra‐specific contests and visual displays. In snapping shrimps of the genus Alpheus, particularly the monogamous species Alpheus brasileiro, both sexes bear enlarged chelipeds, potentially conferring advantages in mate competition or territorial defence ...

It was shown in the past bench-mark simulation of cavitation that a lift of hydrofoil is underestimated in the break-down region in the condition of transient cavitation at high angle of attack in which cavitation has highly unsteady behavior.

ABSTRACT Plant‐based antioxidants are widely incorporated into foods to retard oxidative deterioration and to deliver health‐related benefits. Yet, their in‐product and in vivo performance frequently diverges from predictions based on solution‐phase chemical assays, because matrix interactions, processing history, and host metabolism reshape both ...

Compressibility Effects on Cavity Dynamics behind a Two-Dimensional Wedge
To understand cavity dynamics, many experimental and computational studies have been conducted for many decades. As computational methods, incompressible, isothermal compressible, and fully compressible flow solvers were used for the purpose.

Numerical Study of the Effect of the Leading Edge Shape on Cavitation around Inducer Blade Sections
A numerical study of the cavitation behaviour of two-dimensional hydrofoils simulating a section of an inducer blade is presented. Two leading edge shapes were chosen to approach rocket engine inducer designs.

Experimental Factors and Techniques for Pool Boiling Heat Transfer Enhancement: A Critical Review
ABSTRACT This review presents a comprehensive assessment of active strategies for enhancing pool boiling heat transfer, with a focus on techniques that do not rely solely on the boiling surface modification. It examines a broad range of methodologies including fluid additives, external fields, mechanical interventions, and thermal‐geometric tuning that

Characteristics of Acoustic Field inside Cavitation Tunnel
At present it is usual that the propeller cavitation noise characteristics are evaluated from the measured results at the cavitation tunnel through the scaling laws. However, the test section boundary of the cavitation tunnel is made of plural materials such as stainless steel and acrylic observation window.
