An experimental biomass combustion facility has been
built and established at Oregon State University. The
furnace, or Biomass Combustion Unit ( BCU ), uses an augertype
fuel feed system, grate-type fuel support with under
and over fire air supply.
Fourteen pellet species from five States - Alaska,
Washington, Oregon, Idaho,...
Nickel (Ni)-based alloys with a high chromium (Cr) content are frequently employed in applications where elevated temperatures and/or corrosive environments are present due to their excellent corrosion resistance and mechanical properties. However, a gap exists around the formation, and kinetics of long-range order (LRO) Ni2Cr phase in both model binary...
Flat, laminar, premixed hydrocarbon-air flames were stabilized
on a porous-plate burner. In addition to temperature profiles,
concentration profiles were measured for methane, ethane, ethylene,
propane, acetylene, propylene, carbon monoxide, carbon dioxide and
oxides of nitrogen. Dead space thickness, luminous flame zone
thickness and hydrocarbon disappearance point responses were also
monitored....
This research seeks to identify how changes in temperature and oxygen concentration in the reaction zone affects liftoff heights for moderate or intense low-oxygen dilution (MILD) combustion of a jet fuel and a surrogate fuel. MILD combustion offers a method of burning fuels with reduced CO and NOx production by...
Business and recreation in the modern day world often include air travel as their
cornerstone. Travelers who are disabled and wheelchair bound have to undergo a
transfer process to board and deplane a commercial aircraft. This transfer process is
typically done manually, with agents physically lifting the passenger who is...
Realizing the vast amount of energy available in ocean waves, an industry has emerged that is progressing towards the deployment of grid–connected wave energy converters. Likely to be deployed in arrays, a challenge to the wave energy industry is maximizing the energy production of such arrays. We have been developing...
Interbody fusion cages are increasingly used in the treatment of spinal disease and injury in order to stabilize movement and promote arthrodesis of the vertebral bodies, but the micro-mechanics of the interaction between the cage and the adjacent host bone is not fully understood. This information has bearing on post-surgical...
Heat transfer measurements have been made from a long (L/D = 15)
horizontal cylinder in water parallel to a heated vertical wall. The
cylinder and wall boundary conditions were isothermal, and they were
maintained at equal temperatures. The investigation covered Rayleigh
numbers based on cylinder diameter from 400,000 to 10,000,000....
In a seminal paper published in 1982, scientist have warned that humanity was pushing earth’s ecosystems beyond their capacities to support the web of life. One response to the concern was outlined by NASA with its vision for advanced fixed wing transport aircraft to be environmentally compatible and have revolutionary...
