(2021-06-21)Reaction kinetics between different rock and acid systems have been studied using the rotating disk apparatus (RDA). However, simplifying assumptions have been made to develop the current equations used to interpret RDA ...
-
(2012-11-21)The determination of the leakage and consequently the friction factor is an important part of analyzing the flow through a seal. This is done experimentally by means of a flat plate tester, which allows for the simplified ...
-
(2011-08-08)The design of passive heat removal systems is one of the main concerns for the modular Very High Temperature Gas-Cooled Reactors (VHTR) vessel cavity. The Reactor Cavity Cooling System (RCCS) is an important heat removal ...
-
(2023-05-01)Reduced-order computational design tools used to model hypersonic shock wave / boundary layer interactions have been known to provide unreliable estimates of surface heat flux and total pressure, which are key parameters ...
-
(Texas A&M University. Libraries, 1982)Both fresh and sheared dilute polymer solutions of Separan AP-30 (100, 250, 500 ppm by weight) were used to establish a correlation between rheological properties and turbulent drag reduction in tube flow. The viscosities ...
-
(2020-10-30)The unsteady flow physics promoted by complex turbulent interactions are found in a variety of engineering applications. Classical turbulence studies are strongly motivated by individual canonical flow types, though rarely ...
-
(Texas A&M University. Libraries, 1991)This study discusses the derivation and assessment of a new two-scale dissipation equation, the genesis of which begins with a different fundamental equation than previous multi-scale or single-scale models. The new approach ...

Design and PIV Measurements on a Wire-Wrapped 61-Rod Hexagonal Fuel Assembly Experimental Facility (2017-05-04)The superior uranium utilization efficiency of fast spectrum reactors relative to thermal spectrum reactors was recognized shortly after commercial reactor development started. The sodium fast reactor design, a type of ...

(Texas A&M University, 2004-09-30)Particle-laden turbulent flow through a straight square duct at Reτ = 300 is studied using direct numerical simulation (DNS) and Lagrangian particle tracking. A parallelized 3-D particle tracking direct numerical simulation ...
-
(Texas A&M University. Libraries, 1991)This dissertation details an experimental investigation of the influence of high mainstream turbulence on leading edge film cooling heat transfer. High mainstream turbulence was produced by a bar grid (Tu = 3.3-5.1%), a ...
-
(Texas A&M University. Libraries, 1976)Laminar flow of fluid through reservoir rock can be described using Darcy's Law. If the flow is not laminar, the Forchheimer equation should be used to describe the system. The Forchheimer equation contains a term, β, which ...
-
(2010-10-12)The technical feasibility of hypersonic flight (i.e., re-entry, hypersonic flight vehicles, cruise missiles, etc.) hinges on our ability to understand, predict, and control the transport of turbulence in the presence of ...
-
(2022-07-27)Pressurized Water Reactors (PWRs) are the most common types of electricity generating reactors. Inside of a PWR core, pressurized liquid water is used as a coolant to remove the fission heat generated in the cylindrical ...
-
(2020-07-28)Thrust collars (TCs) are bearing elements used in geared machinery that transmit axial loads from one shaft to another. TCs are primarily used in integrally geared compressors (IGCs), but have applications in gearboxes, ...
-
(Scientific & Academic Publishing, 2015)Vegetation in channels, rivers, reservoirs, and wetlands alters the flow turbulence characteristics. Vegetation has both positive and negative effects, depending on the objective of the hydraulic conduit. For example, it ...
-
(2011-10-21)A new measurement technique called fiber optic reflectometer (FOR) was developed to investigate multiphase flows. The principle and setup of the FOR technique were introduced and applied to various experiments. Based on ...
-
(2013-11-08)A systematic study was performed to investigate the combined effects of hole geometry, blowing ratio, density ratio and free-stream turbulence intensity on flat plate film cooling with forward and backward injection. ...
-
(Texas A&M University. Libraries, 1990)A rectangular turbulent jet has a complex three dimensional flow field. These jets are frequently used in industry, however their flow field dynamics are not understood. The objective of this study was to increase the ...
-
(2021-08-18)Turbulence is an important process governing the mixing of fluid properties in nature. Nowadays, it remains a complex topic in oceanography, and other fields, due to its inherent stochastic nature. It is important in many ...
-
(2020-11-16)Friction loss and heat transfer enhancement measurements were obtained for double-sided, partial length, strip fin arrays within a high aspect ratio (AR=8), rectangular channel. Fins were arranged in a staggered array ...
