What is the rocket plume?

What is the rocket plume?

Rocket plume-surface interaction (PSI) is a multi-phase and multi-system complex discipline that describes the lander environment due to the impingement of hot rocket exhaust on regolith of planetary bodies. This environment is characterized by the plume flow physics, cratering physics and ejecta dynamics.

What is plume effect?

In hydrodynamics, a plume or a column is a vertical body of one fluid moving through another. Several effects control the motion of the fluid, including momentum (inertia), diffusion and buoyancy (density differences). Flows between these two limits are usually described as forced plumes or buoyant jets.

What is the exhaust of a rocket called?

For rocket propulsion the fuel and oxidizer are usually stored as either a liquid or a solid. During combustion, new chemical substances are created from the fuel and the oxidizer. These substances are called exhaust. Soot, for example, is a form of solid exhaust that occurs in some combustion processes.

Are rocket exhausts plasma?

The exhaust is a neutral but highly ionized plasma. One of the studies that remains to be done on this rocket is a careful characterization of the exhaust plume that the rocket produces in various operating configurations.

What is plume and its types?

1) Looping Plume: Occurs in super adiabatic environment. Unstable and need higher stacks. 2) Neutral Plume: Upward vertical rise when ELR = ALR. 3) Coning Plume: When wind velocity is high and sub-adiabatic conditions exist (ELR < ALR). Environment is highly stable.

What is heat plume?

What Does Thermal Plume Mean? Therefore, a thermal plume involves a part of a particular substance such as water or atmosphere which is of a different temperature, usually an elevated temperature which is proceeding from a source and has not yet dissipated into the surrounding substance and equalized temperature.

What are the plumes on Europa?

Scientists have theorized on the origin of the water plumes possibly erupting from Jupiter’s moon Europa. Recent research adds a new potential source to the mix. Plumes of water vapor that may be venting into space from Jupiter’s moon Europa could come from within the icy crust itself, according to new research.
