THEMIS Observations of Particle Acceleration by a Magnetosheath Jet‐Driven Bow Wave
Localized magnetosheath jets with high dynamic pressure are frequently observed downstream of Earth's bow shock. When such a fast magnetosheath jet compresses the ambient magnetosheath plasma, an earthward compressional bow wave could form.

Wave-making resistance reduction characteristics based on spherical bow configuration
Nowadays, the mechanism of a bulbous bow on resistance reduction is still ambiguous. By carry-ing out a study of wave-making resistance based on spherical bow configuration, we can reveal the truth of the problem and find out the effect of reducing ...

Investigation of the Bulbous Bow Effect on the Resistance of a Container Ship by CFD Method
In commercial ships, wave making resistance is a part of total resistance which to reduce it, a bulbous bow is added to the ship bow. To investigate the effect of bulbous bow on total resistance, a container ship model is simulated with and without the ...

Bond-order wave phase, spin solitons and thermodynamics of a frustrated linear spin-1/2 Heisenberg antiferromagnet [PDF]
The linear spin-1/2 Heisenberg antiferromagnet with exchanges $J_1$, $J_2$ between first and second neighbors has a bond-order wave (BOW) phase that starts at the fluid-dimer transition at $J_2/J_1 = 0.2411$ and is particularly simple at $J_2/J_1 = 1/2$.

Analysis of Effect of Bulbous Bow Shape to Ship Resistance in Catamaran Boat
Ship resistance is one of the main factors affecting the design of a ship. Catamaran boat is a ship with small wet surface area that able to reduce drag and improve ship power. Generally, a bulbous bow is implemented to reduce wave resistance because the

The KVLCC2 and its modified hull form were investigated in regular head waves using Unsteady Reynolds Averaged Navier–Stokes (URANS) methods. The modified KVLCC2 (named KWP-bow KVLCC2) is designed for reducing wave reflection from the bow.

First simultaneous measurements of waves generated at the bow shock in the solar wind, the magnetosphere and on the ground [PDF]
On 5 September 2002 the Geotail satellite observed the cone angle of the Interplanetary Magnetic Field (IMF) change to values below 30° during a 56 min interval between 18:14 and 19:10 UT. This triggered the generation of upstream waves at the bow
