MM4TTF: Introduction to Turbulence and Turbulent Flows Case Study 1: Turbulent Boundary Layer Structure Turbulent coherent structures are flow patterns that can be distinguished from each other, as opposed to motions such as eddies which are subject to the phenomenon of superpositioning. Several of these occur in the near-wall region: ‘Low speed streaks’ refer to the regions of relatively slow flow spaced out in a pronounced manner. They generally occur ‘between the legs of hairpin vortices, where

Introduction: The purpose of this experiment was to measure the magnitude of velocity in a flat plate boundary layer in which the pressure was constant. A pitot tube located at the top of the test section that was used to determine the total pressure across the boundary layer. The Pitot tube needed to be able to more along both horizontal and vertical directions for accurate measurements. Five different tubes, aligned along the x-axis, were placed under the wind tunnel test section to measure the

Reviews on previous works The MER is bounded by boundary faults with the orientation of N400E, that form escarpments to the boundary of the rift and the plateau (Boccaletti et al, 1998). Much of Ethiopia and Djibouti has experienced Cenozoic hot spot tectonism, including flood basalt volcanism, plateau uplift, and rifting (Dugda M.T et al, 2007). Kieffer et al., (2004) studied the petrology, geochemistry, and isotopic compositions of the large shield volcanoes, compared their compositions with those

have the same boundaries as the continents or oceans. These plates shift over long periods of time, movements caused by a force resulted from the planet's internal heat energy convecting mantle. There are three main types of tectonic plate boundaries: divergent (when the movement of plate tectonics causes plates to separate, which can lead, on the long term, to the separation of continents), convergent (plates sink beneath each other forming subduction zones) and transform plate boundaries (one plate

Connections to World History Explanation Archaeology Archaeology helps us understand world history by showing us how the ancient groups of people lived before us. They do this by reviewing artifacts left behind by the people of the past. This special branch of study helps us grasp a vast majority of the events that happened before us. Remains left behind are evaluted and preserved to be showcased for future refrences and to give us a look in on who they were. Geography Geography helps us understand

Gabriela Velazques Professor Jackson GEO 305 9 December 2015 Yosemite National Park and the Sierra Nevada: Its Geologic Features and History. History In regards to the geologic components of Yosemite National Park, it essentially has two main parts. The first part is the deposition and deformation of the metamorphic rocks and the emplacement of the granitic rocks during the Paleozoic and Mesozoic periods. The second part is the uplift, erosion, and glaciation that took place with the rocks during

Serpentinite can be found worldwide in mountain chains, greenstone belts and mid-ocean ridges (SRI: Petrography). This group of minerals is produced by the reforming the water content within the ultramafic/mafic igneous rocks. These rocks are typically composed of olivine and peridotite, a form of pyroxene. These igneous rocks undergo serpentinization within a specific region which undergoes metamorphism. Serpentinization

Although convection current in the earth layer are closely associated with the movements of the tectonic plates they also play a role in the formation of rocks, such as the igneous and metamorphic rocks. Igneous rocks form through the solidification of magma or lava. This can occur in two different places, on earth surface and under earth surface. Rocks that form on earth surface are called extrusive, rocks that form under earth's surface are intrusive plutonic rocks. A Metamorphic rock is formed

encircles the Earth. Another boundary is called a convergent boundary. When the crust expands at the divergent boundary the plate is pushed into another plate where it is either sub-ducted or it buckles. This really depends on the type of lithosphere that is involved in the convergence (Kious). This convergence can occur between two ocean plates, two continental plates or an ocean and continental plates. Two of the features that can be found at a convergence boundary is a volcanic arc and a deep

flowing over the body has a small viscosity that is not negligible, the modifying effect appears to be confined to the narrowest regions adjacent to the solid surfaces; these are called boundary layers. Within these layers, there is a rapid change in velocity which gives rise to a large velocity gradient normal to the boundary which produces a shear stress
