What is propellant slosh?

Propellant slosh is a potential source of disturbance critical to the stability of space vehicles. The sloshing dynamics are typically represented by a mechanical model of a spring–mass–damper system.

How can fuel sloshing be prevented?

There are dividers (baffles) in the fuel tank precisely to stop the sloshing. They are just large plates that will stop the fuel from flowing across. High maneuver jets will use bladder tanks (so no air is in the tank with the fuel) as a way to contain the fuel.

What is the fluid sloshing effect?

The phenomenon of sloshing and its effects are related to the movement of free surface of a liquid inside of container. In the article [3] the researchers present the behaviour of the free liquid surface subjected to the dynamic loading which may result in liquid spilling or tank wall damage.

What is tank sloshing?

Sloshing is a violent resonant fluid motion in a moving tank. When a fluid moves and interacts with its container, the dynamic pressures of such an interaction may cause large deformation in the container wall as well as the supporting structure.

Why a vent hole is provided either in the filler neck or in the cap of fuel tank?

A vent hole is provided either in the filler neck or in the cap to have atmospheric pressure in the tank above the fuel.

What is a sloshing sound?

When you start the car, the water pump sends a surge of coolant into the heater core and you hear the sloshing. Obviously, air getting in means coolant is getting out, meaning you have a leak somewhere in the hoses, the radiator, water pump or engine.

Why can I hear water in my car?

The most common cause is a clogged drain trapping water in the heating and cooling system. The water, formed by condensation, usually empties onto the ground. But a clogged drain can cause it to back up, leading to the sloshing sound and even dampness on the passenger-side floor.

Does a diesel tank need to be vented?

Bulk diesel storage tanks should be equipped with a vent line to prevent vacuum formation or overpressure in the tank during drawdown or tank filling, or due to atmospheric temperature changes. Storage tanks used for ethanol-blended diesel fuel need to be fitted with a flame arrester at the vent pipe outlet.

What happens if fuel tank is not vented?

If your fuel tank was not vented, several undesirable things would happen: Storage tank – As ambient temperature changed up or down the tank would undergo stress from pressure or vacuum as the fuel and air inside of the tank expanded or contracted.
