Research on the Hydrodynamic Performance of a Pentamaran in Calm Water and Regular Waves
Applied Sciences, 2023 As a typical multi-hull ship, the pentamaran has a wider deck, higher damage stability, and low-speed seaworthiness in harsh sea conditions compared with other multi-hull types such as the catamaran and trimaran, having more potential for becoming a new ...

Research on Influence of Tank Sloshing on Ship Motion Response under Different Wavelengths
Applied Sciences, 2022 The motion of the liquid-carrying ship under waves is simultaneously affected by the external wave moment and the sloshing moment of the internal tank, which makes the motion of the ship more complicated.

Regular and Mach reflection of shock waves [PDF]
, 1986 The properties that distinguish a shock wave from other waves are that its thickness is negligible compared with other characteristic lengths, and that the state of the medium is changed irreversibly by the passage of the wave.

Cylindrical gravitational waves in expanding universes: Models for waves from compact sources [PDF]
, 2007 New boundary conditions are imposed on the familiar cylindrical gravitational wave vacuum spacetimes. The new spacetime family represents cylindrical waves in a flat expanding (Kasner) universe. Space sections are flat and nonconical where the waves have

Pure loss of stability calculation of naval ship in regular waves
Zhongguo Jianchuan Yanjiu, 2017 The pure loss of stability of a ship is one of the failure modes of the second-generation intact stability criteria. Based on the static surface coordinate system, the generalized pitch angle and draught variable are defined, and a wave equation with ...

Special Purpose Pulsar Telescope for the Detection of Cosmic Gravitational Waves [PDF]
, 2002 Pulsars can be used to search for stochastic backgrounds of gravitational waves of cosmological origin within the very low frequency band (VLF), $10^{-7}$ to $10^{-9}$ Hz. We propose to construct a special 50 m radio telescope.

Journal of Marine Science and Engineering, 2023 Due to the interference between the main hull and the outrigger of the pentamaran, resistance is greatly affected. Therefore, research on the pentamaran front outrigger inclination angle has further practical significance for reducing resistance. In this
