Heat and mass transfer of ambient air flowing over cold fins
(University of Missouri--Columbia, 2016)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Moisture condensation takes place as ambient air is contacting a surface with a temperature lower than the dew point. In the current investigation, a ...
Hybrid thermoelectric ejector - refrigeration system
(University of Missouri--Columbia, 2017)
A mathematical model is developed to predict the refrigeration performance of an ejector powered by waste energy from a thermoelectric cooler. The model is based on constant pressure mixing process and considers the effect ...
Compact oscillating heat pipe and development of fuzzy copper or wicking structures
(University of Missouri--Columbia, 2008)
A central processing units (CPU) calculation speed is limited by the heat it produces. As the number of transistors and the clock speed of CPUs increase they become more powerful, but they also generate more heat which ...
Advanced guidance algorithms for the Ares V cargo launch vehicle
(University of Missouri--Columbia, 2008)
Launch ascent guidance is an area that routinely involves applications of optimization tools and optimal control theory. The vacuum ascent trajectory problem has been formulated as a two-point boundary-value problem with ...
Elastic property prediction of long fiber composites using a uniform mesh finite element method
(University of Missouri--Columbia, 2008)
This research numerically evaluates elastic non-isotropic material properties of fiber reinforced composite materials. Calculations are performed with a finite element mesh composed of a uniform array of three dimensional ...
A comparison of modeling techniques: using the finite element method to determine local displacements in a human hip
(University of Missouri--Columbia, 2007)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Artificial hip implant surgery is required by approximately 120,000 Americans each year. A typical hip replacement requires the surgical insertion of ...
Characterization of mechanical properties of fused deposition modeling manufactured polycarbonate composites
(University of Missouri--Columbia, 2007)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] The use of composites in all products - from sporting goods to bridges to satellites - is increasing due to the ability of composite structures to ...
High strain properties of advanced high strength spot welded steels

Forced convection in nanofluids over a flat plate
(University of Missouri--Columbia, 2008)
This work analyzes the characteristics, flow development, and heat transfer coefficient of nanofluids under laminar forced convection over a flat plate. Nanofluids are engineered colloids composed of a base fluid and ...
Experimental investigation of a novel disc oscillating heat pipe and heat conduction effect on the startup of oscillating motion
(University of Missouri--Columbia, 2009)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] A new disc oscillating heat pipe has been developed and tested for use in high heat flux applications with a localized heat source. The results show ...
Effect of chip thickness, sub-critical bifurcations and process parameters in high-speed milling
(University of Missouri--Columbia, 2010)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] The main focus of the current research is to experimentally and numerically investigate of subcritical bifurcations in milling accounting for actual ...
Development of a two-dimensional human thermal model for EVA applications
(University of Missouri-Columbia, 2002)
The human thermoregulatory system, with its active and passive components, is difficult to model due to nonlinearities, complex interactions, and a lack of understanding of many of the active thermoregulatory mechanisms. ...
Developing and automating time delay system stability analysis of dynamic systems using the Matrix Lambert W (MLW) function method
(University of Missouri--Columbia, 2009)
Stability analysis of time-delayed (TD) systems is not easy to conduct since the addition of delays within a dynamic model results in irrational system equations. Traditional TD analysis methods involve adding approximations ...
