RISOscillating Tidal Barriers and Random Waves
Publisher: American Society of Civil Engineers
Abstract: The interaction between sea waves and the oscillating gates designed to close the three inlets of Venice lagoon and to protect the city from the phenomenon of high waters is studied. Previous studies of this topic, which ...
Conical Failure Surface of Medium-Dense Hostun Sand in Undrained Multidirectional Simple Shear Tests
Publisher: American Society of Civil Engineers
Abstract: Realistic seismic shearing is usually not limited to a single direction. A number of studies on the effect of multidirectional shearing have proven that soil behaves differently under multidirectional loading compared with ...
Application of Unsteady Computational Fluid Dynamics Methods to Trailing Edge Cutback Film Cooling
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The main purpose of this numerical investigation is to overcome the limitations of the steady modeling in predicting the cooling efficiency over the cutback surface in a high pressure turbine nozzle guide vane. Since ...
Radiative Damping and Amplitude of Long-Wavelength Modes in the Stratosphere
Publisher: American Meteorological Society
Abstract: The dependence of radiative damping rates in the stratosphere is investigated as a function of the distribution of active radiative gases and the wavelength of the temperature perturbation. Damping rates are found to depend ...
Stress-Blended Eddy Simulation of Coherent Unsteadiness in Pressure Side Film Cooling Applied to a First Stage Turbine Vane
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Within the framework of scale resolving simulation techniques, this paper considers the application of the stress-blended eddy simulation (SBES) model to pressure side (PS) film cooling in a high-pressure turbine nozzle ...
Wave Boundary Layer over a Rough Bottom at Moderate Reynolds Numbers
Publisher: American Society of Civil Engineers
Abstract: We make use of the partial slip boundary condition, commonly introduced to investigate steady flows, to evaluate the oscillatory flow generated close to a rough sandy bottom by propagating surface waves. Moderate values ...
Investigating the Impacts of Built Environment Knowledge on Hurricane Evacuation Intentions in a College Student Sample: A Test of the Power of Information
Publisher: American Society of Civil Engineers
Abstract: During hurricanes, residents’ evacuation decisions are significantly influenced by their knowledge and risk perceptions. However, many residents may lack a precise understanding of the structural integrity of their homes ...
Personalized Vulnerability Assessment of Customized Low-Rise Wood-Frame Residential Structures under Hurricane Wind Loads: A Flexible Scenario-Based Simulation Approach
Publisher: ASCE
Abstract: Hurricanes are one of the costliest and deadliest weather and climate disasters that impact the United States, largely affecting the residential sector. Residential structures are essential for the health and safety of the ...

Seafloor-Riser Interaction Model
Publisher: American Society of Civil Engineers
Abstract: Fatigue stresses associated with extreme storms, vessel movements, and vortex-induced vibrations are critical to the performance of steel catenary risers. The critical location for fatigue damage often occurs within the ...
