Design And Flow Analysis Of Electromagnetic Plasma Arc Propulsion System

1583 words - 7 pages

1.Introduction
A rocket engine, or simply "rocket", is a jet engine that uses only stored propellant mass for forming its high speed propulsive jet. Rocket engines are reaction engines and obtain thrust in accordance with Newton's third law. Since they need no external material to form their jet, rocket engines can be used for spacecraft propulsion as well as terrestrial uses, such as missiles.Rocket engines as a group have the highest exhaust velocities, are by far the lightest, but are the least propellant efficient of all types of jet engines.
2.Need of Plasma Arc Propulsion
We identify that most of the propulsion process comes under liquid and solid propulsion, but never been implemented on magnet or solar saving fuel systems. Usually solid and liquid propellant produces high thrust, but the problem of solid and liquid propellant is high cost and produce environment effect. In that time very high thrust can be produced by the magnetic plasma arc propulsion system and also it should not affect an environment because inert gases are used in this system. In these system an electromagnetic fields are accelerates the positive and negative charged particles (Plasma) to a very high velocity.
3.Modeling Process
Electromagnetic plasma arc propulsion an advanced modeling apart from the solid and liquid propellant. The propulsion systems were designed according to the same principle of solid and liquid propellant. Most of the rocket engine, the solid has gradient and the liquid has oxidizer and fuel tanks, but the Electromagnetic plasma arc propulsion works on the principle of magnetic principle were coils are made surrounded in Quartz Tube and fuel are converted to energy and and release the plasma arc. We look the studies of these propulsion and compared that electromagnetic plasma arc propulsion is the best and designed it in CATIA software.The full design of Electromagnetic plasma arc propulsion system is shown in figure 1.

4.Analysis Process
Electromagnetic Plasma Arc Propulsion flows are practically done through flow analysis techniques. These process can be done through flow analysis in fluent software. Fluent is compared to be the best analysis for the electromagnetic plasma arc propulsion, because the accuracy of the flow as shown the maximum percentage. All the difficult processes are done through Fluent , because in our analysis we are convert magnetic field into pressure field.
5.Meshing
The entire structure over the propulsion system was meshed with Triangular mesh with an interval of 0.03 . Triangular meshing was chosen because it was finer over the difficult regions when compared to the hexagonal mesh and it is shown in figure.Here applied value of Reynolds number is 50.35.So the laminar ...
