Numerical Analysis of Thermal Behavior and Fluid Flow in Geothermal Energy Piles
(Virginia Tech, 2013-11-11)
Geothermal heat exchangers are a growing energy technology that improve the energy efficiency of heating and cooling systems in buildings. Vertical borehole heat exchangers (BHE) coupled with ground source heat pumps have ...
Methods and Applications of Controlling Biomimetic Robotic Hands
(Virginia Tech, 2014-02-06)
Vast improvements in robotics and wireless communication have made teleoperated robots significantly more prevalent in industry, defense, and research. To help bridge the gap for these robots in the workplace, there has ...
Heat Transfer Characterization in Jet Flames Impinging on Flat Plates
(Virginia Tech, 2015-06-21)
The experimental work involves calculation of radial distribution of heat transfer coefficient at the surface of a flat Aluminium plate being impinged by a turbulent flame jet. Heat transfer coefficient distribution at the ...
Long-Term Cooling of an SBLOCA: Boron Precipitation in the Core, Boron Dilution in the Steam Generators
(Virginia Tech, 2014-01-18)
When soluble boron is used to control reactivity, there are two particular events which can challenge long-term core cooling (LTCC) during the small break loss-of-coolant accident (SBLOCA): boron precipitation and boron ...
Detailed Experimental Measurements of Heat Transfer Augmentation in Internal Channels Using a Thermochromic Liquid Crystal Technique
(Virginia Tech, 2015-06-22)
Design of internal cooling channels for gas turbine blade is critical to system performance. To achieve maximum efficiency, i.e. maximum cooling with minimum coolant usage, intensive research is required to optimize heat ...
A study of a method for testing boiler feedwater treatments in Duplex Test Boiler
(Virginia Agricultural and Mechanical College and Polytechnic Institute, 1938)
The Influence of Development and Fan/Screen Interaction on Screen-Generated Total Pressure Distortion Profiles
(Virginia Tech, 2014-02-03)
The rising interest in fan performance in the presence of total pressure distortion, a topic of fundamental interest for integrated airframe/engine architectures, has led to increased research in ground based testing ...
Unmanned Aerial System for Monitoring Crop Status
(Virginia Tech, 2014-01-11)
As the cost of unmanned aerial systems (UAS) and their sensing payloads decrease the practical applications for such systems have begun expanding rapidly. Couple the decreased cost of UAS with the need for increased crop ...
Fluidic Flexible Matrix Composite Wafers for Volume Management in Prosthetic Sockets
(Virginia Tech, 2015-05-28)
Persons with transfemoral (above knee) and transtibial (below knee) prostheses experience changes in the volume of their residual limb during the course of the day. These changes in volume unavoidably lead to changes in ...
Prospects for the Collision-Free Car: The Effectiveness of Five Competing Forward Collision Avoidance Systems
(Virginia Tech, 2013-12-17)
Rear-end collisions in which the leading vehicle was stationary prior to impact and at least one vehicle was towed from the crash site represent 18% of all yearly crashes in the United States. Forward Collision Avoidance ...
