RISNumerical Study of the Performance of Combined Spike and Transpiration Cooling Concept for Nose Cone under Hypersonic Conditions
Publisher: American Society of Civil Engineers
Abstract: During high-speed flight of hypersonic vehicles, the nose cone’s stagnation point encounters a severe aerothermodynamic environment. Although traditional transpiration cooling can effectively decrease the structural ...
Lattice Boltzmann Method for Advection and Anisotropic Dispersion Equation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A lattice Boltzmann method is developed for the solution of the advection and anisotropic dispersion equation. In the approach, a novel local equilibrium distribution function is formulated to ...
Global Transport on a Spherical Multiple-Cell Grid
Publisher: American Meteorological Society
Abstract: econd- and third-order upstream nonoscillatory (UNO) advection schemes are applied on a spherical multiple-cell (SMC) grid for global transport. Similar to the reduced grid, the SMC grid relaxes the Courant?Friedrichs?Lewy ...
Upstream Nonoscillatory Advection Schemes
Publisher: American Meteorological Society
Abstract: Upstream nonoscillatory (UNO) advection schemes are derived by optimizing existing classical advection schemes and combining them in different monotonic zones to avoid flux limiters for simplicity. The UNO schemes are ...
Velocity-Depth Coupling in Shallow-Water Flows
Publisher: American Society of Civil Engineers
Abstract: The two-dimensional shallow-water flow equations are first written in strong conservation form and are used for developing the flow model. In the discretization equations, based on the control volume method, the velocity ...
Probability Analysis of Aberrant Ship Collision with Sea-Crossing Bridges Considering Wind and Current
Publisher: ASCE
Abstract: The worldwide occurrence of numerous ship–bridge collisions has prompted a substantial concern regarding the safety of sea-crossing bridges. The majority of conventional risk models for ship–bridge collisions assume that ...
Estimation of Fatigue Parameters and Life Prediction for Orthotropic Steel Deck Based on Reverse Markov Theory
Publisher: American Society of Civil Engineers
Abstract: Orthotropic steel deck (OSD) is a widely used lightweight steel structure known for its high load-bearing capacity. However, it is susceptible to cracking, particularly in locations that exhibit structural degradation. In ...
New Mesoscale Phase Field Model for Analysis of FRP-to-Concrete Bonded Joints
Publisher: ASCE
Abstract: Externally bonded fiber-reinforced polymer (EB-FRP) laminates have become popular for strengthening existing reinforced concrete (RC) structures. However, the high tensile strength of the FRP laminate is often not fully ...
Fatigue Tests of 8‐yr Weathered A588 Steel Weldment
Publisher: American Society of Civil Engineers
Abstract: Fatigue tests of 62 specimens determined the effect of 3‐year, alternate, and 8‐year weathering on the number of cycles to failure of a transverse stiffener detail fabricated from ASTM A588 weathering steel. These three ...
Beam-Truss Model of Steel-Concrete Composite Box-Girder Bridges
Publisher: American Society of Civil Engineers
Abstract: In this paper, a beam-truss model is introduced for the design analysis of composite box-girder bridges. An integrated research program for beam-truss models, including modeling implementation, analysis, and application, ...
