Slosh Baffle
A slosh baffle is a device used to dampen the adverse effects of liquid slosh In fluid dynamics, slosh refers to the movement of liquid inside another object (which is, typically, also undergoing motion). Strictly speaking, the liquid must have a free surface to constitute a slosh dynamics problem, where the dynamics of t ... in a tank. Slosh baffles have been implemented in a variety of applications including tanker trucks, and liquid rockets, although any moving tank containing liquid may employ them. Baffle rings Baffle rings are rigid rings placed within the inside of a tank to retard the flow of liquid between sections. The location and orifice size of the rings yield varying performance for a given application. See also Baffle blocks References Fluid dynamics {{fluiddynamics-stub ...

Slosh
In fluid dynamics, slosh refers to the movement of liquid inside another object (which is, typically, also undergoing motion). Strictly speaking, the liquid must have a free surface to constitute a slosh dynamics problem, where the dynamics of the liquid can interact with the container to alter the system dynamics significantly. Important examples include propellant slosh in spacecraft tanks and rockets (especially upper stages), and the free surface effect (cargo slosh) in ships and trucks transporting liquids (for example oil and gasoline). However, it has become common to refer to liquid motion in a completely filled tank, i.e. without a free surface, as "fuel slosh". Such motion is characterized by "inertial waves" and can be an important effect in spinning spacecraft dynamics. Extensive mathematical and empirical relationships have been derived to describe liquid slosh. These types of analyses are typically undertaken using computational fluid dynamics and finite element met ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tank Truck
A tank truck, gas truck, fuel truck, or tanker truck (American English) or tanker (British English) is a motor vehicle designed to carry liquids or gases on roads. The largest such vehicles are similar to railroad tank cars, which are also designed to carry liquid loads. Many variants exist due to the wide variety of liquids that can be transported. Tank trucks tend to be large; they may be insulated or non-insulated; pressurized or non-pressurized; and designed for single or multiple loads (often by means of internal divisions in their tank). Some are semi-trailer trucks. They are difficult to drive and highly susceptible to rollover due to their high center of gravity, and potentially the free surface effect of liquids sloshing in a partially filled tank. History Oil Prior to tank distribution, oil was delivered in cans. From the 1880s, it was distributed in horse-drawn tanks. In 1910, Standard Oil started using motor tankers. Anglo American Oil introduced underg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Liquid-propellant Rocket
A liquid-propellant rocket or liquid rocket uses a rocket engine burning liquid rocket propellant, liquid propellants. (Alternate approaches use gaseous or Solid-propellant rocket , solid propellants.) Liquids are desirable propellants because they have reasonably high density and their combustion products have high Specific impulse, specific impulse (''I''sp). This allows the volume of the propellant tanks to be relatively low. Types Liquid rockets can be monopropellant rockets using a single type of propellant, or bipropellant rockets using two types of propellant. Tripropellant rockets using three types of propellant are rare. Liquid oxidizer propellants are also used in hybrid rockets, with some of the advantages of a solid rocket. Bipropellant liquid rockets use a liquid fuel such as liquid hydrogen or RP-1, and a liquid oxidizer such as liquid oxygen. The engine may be a cryogenic rocket engine, where the fuel and oxidizer, such as hydrogen and oxygen, are gases which hav ...

Baffle Blocks
Baffle blocks are concrete structures with different shapes, for example trapezoidal,Effect of baffle block configurations on characteristics of hydraulic jump in adverse stilling basins Ali Abbas,Haider Alwash, Ali Mahmood, MATEC Web of Conferences 162, 03005 (2018), ''matec-conferences.org'' used in flowing water to reduce its force. They are arranged in several rows in stilling basins. They are used in spillways and dams, in irrigation systems, to protect fishes in rivers with hydrotechnical installations, to improve sediment deposition, as a solution to scouring in hydraulic projects and in flood control.
