Study of frost growth on heat exchangers used as outdoor coils in air source heat pump systems
(2011-05)
Scope and Method of Study: During winter heating operation, the outdoor coil of a heat pump acts as an evaporator and when the ambient temperature is near freezing, the moisture in the atmospheric air freezes on the coil ...
Injection molded poly(ethylene terephthalate)-graphene nanocomposites
(2015-05)
Polymer nanocomposites are known for their superior properties (mechanical, thermal, etc.) compared to conventional composites. Nanoscale reinforcements are used to make such composites as they have fewer defects and higher ...
Closed cycle propulsion for small unmanned aircraft
(2015-07)
This study evaluates the merit of closed cycle propulsion systems for use in unmanned systems. The complexity and added weight of closed cycle engines is offset by benefits in high altitude performance, operation in polluted ...
Honeycomb in hybrid composite armor resisting dynamic impact
(2015-07)
Behind Armor Blunt Trauma (BABT) is an emerging problem in body armor due to excessive deformation resulting from projectile impact. A potential to reduce BABT has been identified by incorporating a honeycomb layer in a ...
Development of optimized path planning and autonomous control for return-to-point vehicle of high altitude ballooning
(2014-07)
In 2004, The Atmospheric and Space Threshold Research Oklahoma (ASTRO) program was launched to provide access to the near space environment for both educational and research purposes. Mainly, this ASTRO vehicle consisted ...
Development of nonlinear finite element codes for stability studies of web material with strain state dependent properties
(2011-12)
Scope and Method of Study: The objective of the proposed research is to develop user friendly finite element codes that will solve nonlinear instability problems associated with strain state dependent material properties ...
Effects of ion irradiation on the mechanical properties and structural evolution of sol-gel derived hybrid silicate thin films
(2015-07)
A study of the effects of ion irradiation on the surface mechanical properties and structural evolution of sol-gel derived hybrid silicate thin films has been conducted. Green films were synthesized through a sol-gel process ...
