This research effort presents a tabu search algorithm to solve the dynamic airlift loading problem. Given a set of palletized cargo items which require transportation from an aerial port of embarkation to an aerial port of debarkation within a pre-specified time frame, the dynamic airlift loading problem seeks to partition the pallets into aircraft loads, select an efficient and effective subse...

The objective of this study was to investigate the hydrodynamics and gas-liquid mass transfer coefficient an external-loop airlift reactor (ELAR). ELAR operated in three cases: different inlet velocities fluids, alcohols solutions (water, 0.5% methanol, ethanol, propanol butanol) concentration methanol (0%, 0.5%, 1%, 2% 5%). influence superficial gas velocity various diluted alcohol on studied....

This paper presents the results of a simulation model designed to estimate aircraft Mission Capable Rates (MCR) for the United States Air Force. This simulation model originated out of the need to estimate the MCR for different modernization schemes to be implemented on the Air Force C-5 Galaxy aircraft. Assigned to the Air Mobility Command (AMC), the C-5 is one of our nation’s only two strateg...

BACKGROUND: Airlift solid–liquid two-phase partitioning bioreactors (SL-TPPBs) have been shown to be effective for the treatment of gas streams containing benzene, toluene, ethylbenzene and o-xylene (BTEX). The airlift SL-TPPB is a low-energy system that utilizes a sequestering phase of solid silicone rubber beads (10%v/v) that will uptake and release large amounts of BTEX in order to maintain ...
