Development of an Implicit Numerical Model for Calculation of Sub and Super Critical Flows
A two dimensional numerical model of shallow water equations was developed tocalculate sub and super-critical open channel flows. Utilizing an implicit scheme the steady stateequations were discretized based on control volume method. Collocated grid arrangement was appliedwith a SIMPLEC like algorithm for depth-velocity coupling. Power law scheme was used fordiscretization of convection and dif...

متن کاملDeficits for bursty latency-critical flows: DRR++
Fair Queuing was invented to ensure that every flow gets its fair share of the total bandwidth. Efficient Fair Queuing Using Deficit Round-Robin, DRR, proposed by Shreedhar and Varghese [1], reduces the work to process each packet from O(log(n)) to O(1). DRR was also extended to accommodate latency-critical flows. DRR+ uses a timer to police each latency-critical flow, and was shown to have a l...
متن کاملNumerical Simulation of Failure Behavior of Granular Debris Flows Based on Flume Model Tests
In this study, the failure behaviors of debris flows were studied by flume model tests with artificial rainfall and numerical simulations (PFC(3D)). Model tests revealed that grain sizes distribution had profound effects on failure mode, and the failure in slope of medium sand started with cracks at crest and took the form of retrogressive toe sliding failure. With the increase of fine particle...
متن کاملCritical Thresholds in a Relaxation Model for Traffic Flows
In this paper, we consider a hyperbolic relaxation system arising from a dynamic continuum traffic flow model. The equilibrium characteristic speed resonates with one characteristic speed of the full relaxation system in this model. Thus the usual sub-characteristic condition only holds marginally. In spite of this obstacle, we prove global in time regularity and finite time singularity formati...
