Active Suppression of Vortex-Driven Combustion Instability Using Controlled Liquid-Fuel Injection

Active Suppression of Vortex-Driven Combustion Instability Using Controlled Liquid-Fuel Injection

Abstract :-
Combustion instabilities remain one of the most challenging problems encountered in developing propulsion and power systems. Large amplitude pressure oscillations, driven by unsteady heat release, can produce numerous detrimental effects. Most previous active control studies utilized gaseous fuels to suppress combustion instabilities. However, using liquid fuel to suppress combustion instabilities is more realistic for propulsion applications.

Abort Trajectories for Manned Lunar Missions

Abort Trajectories for Manned Lunar Missions

Abstract :-
With NASA’s renewed focus towards a permanent human presence on the moon, comes the development of the Crew Exploration Vehicle. Unforeseen circumstances can induce emergency situations necessitating contingency plans to ensure crew safety. It is therefore desirable to define the feasibility of a direct abort from an outbound translunar trajectory. Continue reading Abort Trajectories for Manned Lunar Missions

Adsorption Humidity Effects, Microparticle Rate Behavior and Thermal Swing Adsorption

Abstract :-
Application of adsorption processes for air purification requires an approach, which accounts for the presence of humidity. Four separate but related studies are conducted to examine the adsorption processes. A new pure component adsorption isotherm is developed to describe Type 5 adsorption. The results are used to correlate data of water on activated carbon. Continue reading Adsorption Humidity Effects, Microparticle Rate Behavior and Thermal Swing Adsorption
