An investigation into thermoelectric coolers
(University of Missouri--Columbia, 2018)
A thermoelectric cooler (TEC) is a type of cooler that uses the electricity between the junction of two materials to cause a temperature drop. These coolers operate using the Peltier effect. Effectively, a TEC uses electrical ...
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 ...
Automated trajectory generation and guidance for a new launch vehicle flight phases
(University of Missouri--Columbia, 2010)
Much effort has been put into developing technologies for next generation re-usable launch vehicles. Fully re-usable launch vehicles include a booster stage that is designed to land, usually near the launch site, after it ...
Sensitivity analysis and optimal design of conventional and magnnetorheological fluid brakes
(University of Missouri--Columbia, 2018)
Mechanical and electrical brakes have dominated the braking industry for many years and will most likely continue to do so for the foreseeable future due to their low cost and adequate operating performance, wide range of ...
Air-side heat transfer enhancement by self-agitators
(University of Missouri--Columbia, 2019)
Airfoil-based self-agitators (AFAs), bio-inspired rectangular-shaped self-agitators (RSAs), and caudal-fin inspired hourglass-shaped self-agitators (CHSAs) were installed inside plate-fin heat exchanger. The heat transfer ...
Theoretical analysis of heat and mass transfer processes in an evaporative cooling system with zeolite desiccant powered by solar energy
(University of Missouri--Columbia, 2018)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Concerns about energy sources depletion and environmental pollution issues have been raised and is a top priority of the global community. Refrigeration ...
3D printing of energetic material
(University of Missouri--Columbia, 2019)
In the world of macro-scale energetics, the problems of cost effectiveness, scalability, and manufacturability are of prime importance. But with the advent of 3D printing, a solution for scalability is in reach. In this ...
Thermal mechanical analysis of applications with internal heat generation
(University of Missouri--Columbia, 2014)
Analysis of oscillatory flow and heat transfer in an oscillating heat pipe
(University of Missouri--Columbia, 2010)
An advanced physical and theoretical model of a U-shaped minichannel - a building block of an Oscillating Heat Pipe (OHP) - has been developed step by step. a) The gravity and pressure loss at the bend are included in the ...
Modeling the inertial torque imbalance and foundation forces within an inline internal combustion engine : quantifying the equivalent mass approximation
(University of Missouri--Columbia, 2018)
single-piston engine. The next largest foundation forces are exhibited by a 2-piston engine, followed by a 3e-piston engine, and that a dramatic reduction in the foundation forces and torque imbalance may be obtained by using 4 or more pistons...
A new lumped parameter model for coronary blood flow, using nondimensional analysis
(University of Missouri--Columbia, 2019)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] The studies of the coronary circulation hemodynamics are of great importance due to the high mortality and morbidity associated with coronary diseases. ...
Mechanical behavior of transparent fiber reinforced polyester composites at extreme temperatures
(University of Missouri--Columbia, 2018)
Selecting materials for harsh or extreme environmental conditions can be a challenge. The combination of a harsh environment, large forces over extended periods and the need for lowest possible cost restricts the choice ...
