Subharmonic Generation of Edge Waves by Nonuniform Incident Waves
Cellular-Automata for Hydrodynamic Modeling
A two-dimensional fluid continuum system can be modeled using a discrete field of particles that interact according to simple deterministic rules. The methodology is called Cellular Automata....
An Efficient, Accurate Technique for Navier-Stokes Solution
Solution of the Navier-Stokes equations for a Newtonian, incompressible fluid (such as water) requires both accuracy in the assuring conservation of mass and efficiency of convergence....
Discharge and Depth Behind a Partially Breached Dam
The role that the velocity-distribution correction factor plays in the determination of the flood discharge and corresponding flow depth behind a partially breached dam is investigated....
Limitations of Saint Venant Equations to Model Flood Waves
The subject of this paper is in direct contrast to all previously known research efforts. Previous effort has focused on simplified forms of Saint Venant using approximate routing models...
Modeling Unsteady One Dimensional Open Channel Flow Using the Slope Friction Form of the Saint-Venant Equations
The flow of water in open channels has been an important research topic for many years. In 1871, B. De. Saint-Venant published a set of equations that attempted to quantify the physical...
Infiltration as a Dependent Variable in Modeling Furrow Irrigation
Most surface irrigation models assume that infiltration is independent of surface flow hydraulics. However, wetted perimeter has been shown to significantly affect infiltration in furrows....
Response Charts for Designing Against Nuclear Overpressures
The single-degree-of-freedom equation of motion for an elastic-plastic system with a nuclear airblast overpressure forcing function is nondimensionalized and solved. Solutions are presented...
Limiting Performance and Design by Reanalysis of Structures for Blast Resistance
Limiting performance is the absolute optimal response of a structure under a specified transient load. Reanalysis methods are computational techniques for analyzing locally modified large-scale...
Time Domain Structural Parameters Identification
Identification techniques for linear lumped-parameters models of vibrating structures are critically assessed using data produced by numerical simulations. The structural model is excited...
The Lanczos Method in Structural Dynamics
The solution of the equations of motion often results in the solution of an eigenvalue problem in which the system matrices are large. Traditionally, the solution of this problem has employed...
