Photographic analysis of buoyant stack plumes in a laboratory model of the turbulent mixed layer

Creator:: Hukari, Neil F.
Abstract:: Four buoyant plumes were produced within a laboratory convectively mixed layer from a source height of about z[subscript s] = 0.15 h, where h is the height of the convectively mixed layer. The projected images of these plumes in the X-Z plane were analyzed using a densitometer (photomultiplier tube) to...

A study of turbulence in the viscous sublayer and logarithmic region of the bottom boundary layer

Creator:: Chriss, Terry Michael
Abstract:: Detailed current profiles between the sediment-water interface and 20 cm above it reveal a viscous sublayer in the bottom boundary layer on the Oregon continental shelf. Data from three field experiments are used to test fundamental assumptions about boundary layer flow in the ocean. The first study, discussed in Chapter...

Atmospheric boundary layer coupling to midlatitude mesoscale sea surface temperature anomalies

Creator:: Thum, Nicolai
Abstract:: This thesis examines the mechanisms that couple the monthly-averaged atmospheric boundary layer (ABL) to open-ocean sea surface temperature (SST) perturbations on scales of 50-500 km. The observed positive correlation between surface wind speed anomalies and SST anomalies is successfully simulated using the Weather Research and Forecasting (WRF) model. In numerical...

Observational studies of stable nocturnal boundary layers: intermittent turbulence, sensible heat budgets and observational errors

Creator:: Nakamura, Reina
Abstract:: Atmospheric boundary layers become stably stratified at night over land when the surface becomes colder than the air layer above. In stable nocturnal boundary layers (SNBL), turbulence becomes weak and intermittent, terrain-induced phenomena such as drainage currents or gravity-waves emerge and the surface heterogeneity is enhanced. Because of their complexity...

An experimental study of laminarization induced by acceleration and curvature

Creator:: Jackson, R. Brian
Abstract:: The Generation IV Very High Temperature Reactor (VHTR) design is being actively studied in various countries for application due to its inherent passive safe design, higher thermal efficiencies, and proposed capability of providing high temperature process heat. The pebble bed core is one of two core designs used in gas...

Linking dynamics of the near-surface flow to deeper boundary layer forcing in the nocturnal boundary layer

Creator:: Smoot, Alexander R.
Abstract:: Weak-wind flow in the nocturnal boundary is one of the most poorly understood problems in the field of meteorology. The understanding of weak-wind flows is essential for the improvement of regulatory dispersion models which are currently rendered invalid under weak-wind conditions and stable stratification. Recently there have been increased efforts...

A calculation of the suction requirements to prevent boundary layer separation on a circular cyclinder

Creator:: Corsiglia, Victor R.
Abstract:: An investigation was made to test the method of Head on the flow about a circular cylinder with suction. The method of Head is an approximate method of obtaining solutions to the boundary layer equations. The method was adapted to the digital computer to facilitate performing the calculations, and a...

Estimation of momentum, heat and mass transfer in laminar boundary layers

Creator:: Myers, Gary Allen
Abstract:: Sisson's formally exact series solution for momentum, heat and mass transfer in steady two-dimensional or axi-symmetrical constant-property, laminar boundary layer flow was examined. A new series was proposed for the boundary condition accounting for the mass transfer at the surface of the body on which the boundary layer is formed....

An examination of structure and parameterization of turbulence in the stably-stratified atmospheric boundary layer

Creator:: Ruscher, Paul Harold
Abstract:: The very stable boundary layer is a region of the atmosphere typified by large vertical gradients of temperature and momentum. Analysis of very stable atmospheric flows is complicated by the presence of nonlinear interactions among gravity waves, shear-driven overturning circulations, two-dimensional vortical modes and intermittent turbulence in various stages of...
