Hybrid RANS/LES models, capable of transitioning through arbitrary levels modeled and resolved turbulence, aim to ameliorate both RANS deficiencies LES expense. We propose a method combining active forcing the flow field, where appropriate, with splitting standard single turbulence model into separate responsible for either unresolved stress or dissipation, which adapts that $i\phantom{\rule{0}...

Oscillating water column (OWC) is an advanced form of wave energy converter (WEC). This study aims at improving the efficiency amended OWC through a novel methodology for simulating several vertical plates within chamber. paper provides numerical investigation considering one, two, three, and four plates. The open field operation manipulation (OpenFOAM) solver verified based on Reynolds-Average...

The increasing complexity of engineering problems makes the coupling of multiple simulation codes attractive. In fluid mechanical applications, the physical range of flow phenomena that can be modeled can be extended significantly by coupling flow solvers based on the Reynolds-averaged Navier Stokes (RANS) approach and on LargeEddy Simulations (LES). These separate flow solvers run simultaneous...

Standardization efforts towards achieving 4G objectives have resulted in the development of Orthogonal Frequency Division Multiple Access (OFDMA) technology. The flexible frequency assignment enabled by OFDMA allows for the introduction of new network elements such as distributed antenna ports, femto base-stations, and relays, and new coordinated multipoint (CoMP) transmission and reception tec...

Recent works have valid the chance of increase the energy potency in radio access networks (RANs). done by dynamically turning on/off some base stations (BSs). According to this paper, to extend the analysis over Base Stations switching operations that ought to match up with traffic load variations. . we have a tendency to first of all formulate the traffic variations as a Markov Decision Proce...

Recent many works have concentrated on dynamically turning on/off some base stations (BSs) in order to improve energy efficiency in radio access networks (RANs). In this survey, we broaden the research over BS switching operations, which should competition up with traffic load variations. The proposed method formulate the traffic variations as a Markov decision process which should differ from ...

We introduce recurrent additive networks (RANs), a new gated RNN which is distinguished by the use of purely additive latent state updates. At every time step, the new state is computed as a gated component-wise sum of the input and the previous state, without any of the non-linearities commonly used in RNN transition dynamics. We formally show that RAN states are weighted sums of the input vec...

Computational fluid dynamics (CFD) is increasingly used to simulate complex industrial systems. Most CFD analysis relies on the Reynolds-averaged Navier-Stokes (RANS) approach and traditional two-equation turbulence models. Higher-fidelity approaches to the simulation of turbulence such as wallresolved large eddy simulation (LES) and direct numerical simulation (DNS) remain limited to smaller a...
