Large-eddy Simulation of Boundary Layer Transition on Swept Wings
The large-eddy simulation of the spatial evolution of a stationary cross ow vortex packet in a three-dimensional boundary layer was performed. Although a coarse grid was used (compared to that required by a direct numerical simulation) the essential features of the disturbance evolution, such as the spanwise disturbance spreading and the vortex rollover, were captured accurately. The eddy visco...
متن کاملOptimizing profits from hydroelectricity production
This paper presents a deterministic and a stochastic mathematical model for maximizing the profits obtained by selling electricity produced through a cascade of dams and reservoirs in a spot market. The first model is based on deterministic electricity prices while the other integrates stochasticity through the management of a tree of potential price scenarios. Numerical results based on histor...
متن کاملPutting Wings on SPHINCS
SPHINCS is a recently proposed stateless hash-based signature scheme and promising candidate for a post-quantum secure digital signature scheme. In this work we provide a comparison of the performance when instantiating SPHINCS with different cryptographic hash functions on both recent Intel and AMD platforms found in personal computers and the ARMv8-A platform which is prevalent in mobile phon...
متن کاملApplication of Variable Leading-Edge Roughness for Transition Control on Swept Wings
For transition to turbulence in crossflow-dominated swept-wing boundary layers, details of the strongly nonlinear nature of the stationary primary instability are well understood both experimentally and theoretically. It is the particular action of the nonlinearities that makes possible a transition control scheme using subcritically spaced leading-edge surface roughness arrays. What is desired...
متن کاملHydroelectricity production and forest conservation in watersheds.
Globally, particularly in developing countries, hydroelectricity production and economic growth occur together with ecosystem/biodiversity conservation in watersheds. There is a relationship between hydroelectricity production and ecosystem/biodiversity conservation in watersheds, centering on the supply and demand for ecosystem services of river water flow regulation and sediment retention. He...
