Supersonic Retro-Propulsion Computational Fluid Dynamics Analysis Applied to Future Mars Mission
… was exposed to during its landing sequence. The plume expansion was analyzed for various cases, moving from free stream to supersonic conditions. Several computational methods were also examined to prove the model's accuracy. The mesh, physics models, and boundary conditions were ultimately …

Development of a Parallel Electrostatic PIC Code for Modeling Electric Propulsion
… The parallel code was also used to simulate the plume expansion of an ion thruster array composed of three NSTAR thrusters. Results showed that the multiple beams merge to form a single plume similar to the plume created by a single ion thruster.

Experimental and theoretical characterization of a Hall thruster plume
… of the Hall thruster, the interaction of its plume with the spacecraft remains an important integration issue. Because in-flight data fully characterizing the plume in the space environment are currently unavailable, laboratory measurements are often used to understand plasma expansion and …

Picosecond Infrared Lasers (PIRL): Applications in Biodiagnostics and Towards Quantitative Mass Spectrometry
… field cannot be observed in the early stage of plume expansion but that the polymers stay intact with shedding of the water solvation layers. These results illustrate that selective excitation of the water provides the desired ablation physics.

Interactions of intense optical and extreme-ultraviolet lasers with atoms and solids
… collide. The collision of these two expanding plumes will eventually lead to a region in space where the counter-streaming plumes begin to stagnate. As plasma expansion continues the temperature and density of material at this interface increases significantly, a dense stagnation layer is …
