(2018-05-02)The helical coil steam generator is a type of tube and shell heat exchanger that is proposed for many small modular and Gen IV reactor designs. It is favored due to the higher heat transfer it provides compared to traditional ...
-
(2023-03-08)Implementing particle image velocimetry (PIV) data collection in wind tunnel testing increases understanding of the model flow field by providing velocity field data, as compared to single-point velocity data produced by ...
-
(Texas A&M University, 2005-11-01)An investigation of turbulent structure modification of a boundary layer for a fully developed channel flow by microbubble injection close to the upper wall was carried out using Particle Image Velocimetry (PIV). Two-dimensional ...
-
(2016-08-05)The very high temperature reactor (VHTR) is one of the most promising next generation reactors which will be commercialized in 2030. A loss-of-coolant accident (LOCA) is a major accident scenario in which the primary coolant ...
-
(2017-12-08)This research introduces a novel method to estimate nearshore bottom topography using an unmanned aerial vehicle (UAV), or drone. The UAV was manipulated over the area of interest to film video, and the Particle image ...
-
New and improved thermal hydraulic data is essential for ensuring safe operation for Pressurized Water Reactors (PWR). Excessive fission product buildup on fuel rods produces uneven subcooling during operation which poses ...
-
(2014-12-16)An experimental investigation of the effects of Initial Conditions (ICs) on Rayleigh-Taylor Instability (RTI) is performed using theWater Channel facility at Texas A&M University. Hot and cold water (with a temperature ...
-
(2009-05-15)The overarching objective of this research project was to gain improved basic understanding of the fluid mechanisms governing the development of secondary flow structures in complex, three-dimensional inlet ducts. To ...

(2012-02-14)Dynamic stall has proven to be a complex problem in helicopter aerodynamics because it limits the helicopter flight regime. Dynamic stall is characterized by drastic increases in lift and a delay of stall due to rapid ...
-
(2019-04-19)In the U.S., the helium-cooled VHTR has become the centerpiece of DOE NGNP program. Among the VHTR design’s many technological innovations is a safety system called reactor cavity cooling system (RCCS). The RCCS provides ...
-
(2019-11-04)Liquid metal fast reactors often use a tightly packed triangular lattice of fuel pins that are helically wrapped with a wire spacer, enclosed in a hexagonal duct. These reactors are thought to suffer from partial or total ...
-
(Texas A&M University, 2005-11-01)The effects of microbubbles injection in the boundary layer of a turbulent channel flow are investigated. Electrolysis demonstrated to be an effective method to produce microbubbles with an average diameter of 30 ??m and ...
-
(Texas A&M University, 2006-04-12)Particle Image Velocimetry (PIV) and pressure measurement techniques were performed to investigate the drag reduction due to microbubble injection in the boundary layer of a fully developed turbulent channel flow. ...
