A step towards reduced order modelling of flow characterized by wakes using Proper Orthogonal Decomposition

https://www.sintef.no/en/publications/publication/?pubid=CRIStin+1528534

High fidelity simulations of flow can be quite demanding, involving up to O(106) to O(109) degrees of freedom, and several hours or days of computational time, even on powerful parllel architectures. These techniques become prohibitive when expected to deal quickly and efficiently with repetitive so...

Quasi-Static & Dynamic Numerical Modeling of Full Scale NREL 5MW Wind Turbine

https://www.sintef.no/en/publications/publication/?pubid=CRIStin+1528533

Simulations of the National Renewable Energy Laboratory (NREL) 5MW wind turbine under quasi-static Multiple Reference Frame (MRF) and dynamic Sliding Mesh Interface (SMI) methodologies are presented. Two reference zone approach is considered, inertial and moving reference frame. The former contains ...

A full-scale 3D Vs 2.5D Vs 2D analysis of flow pattern and forces for an industrial-scale 5MW NREL reference wind-turbine

https://www.sintef.no/en/publications/publication/?pubid=CRIStin+1528532

NREL 5MW reference turbine, which is a popular, realistic and standardized industrial scale offshore turbine model, is used in this work for understanding the associated flow-complexities and for testing models. For such full-scale wind-turbine, the wish list is towards a accurate real-time predicti...

Demonstrating the impact of bidirectional coupling on the performance of an ocean-met model

https://www.sintef.no/en/publications/publication/?pubid=CRIStin+1528531

The mass, momentum and energy fluxes between the atmosphere and ocean surface depend on the state of the ocean surface. The fluxes in turn can significantly alter the nature of the marine boundary layer and the state of the ocean surface. These interactions can be modelled deterministically using a ...

Industrial scale turbine and associated wake development-comparison of RANS based Actuator Line Vs Sliding Mesh Interface Vs Multiple Reference Frame method

https://www.sintef.no/en/publications/publication/?pubid=CRIStin+1528528

This current work compares the three methodologies (Actuator Line model (ALM), Sliding Mesh Interface (SMI) and Multiple Reference Frame (MRF)) in modeling an industrial scale reference turbine at different tip speed ratios (TSR). The comparison shows that all the 3 models qualitatively predict the ...

Analysis of Unsteady Hydrodynamics Related to Vortex Induced Vibrations on Bluff-Bodied Offshore Structure

https://www.sintef.no/en/publications/publication/?pubid=CRIStin+1514207

Flows around a fixed cylinder with uniform and pulsating inflow conditions at different Reynolds numbers are simulated using Large Eddy Simulation (LES). For pulsating inflow, a sinusoidal profile, with an amplitude ΔU and a pulsation frequency fe, is superimposed onto the mean velocity U∞ at the in...

A Step Towards a Reduced Order Modelling of Flow Characterized by Wakes Using Proper Orthogonal Decomposition

https://www.sintef.no/en/publications/publication/?pubid=CRIStin+1514206

High fidelity simulations of flow might be quite demanding, because they involve up to O(106 – 109) degrees of freedom and several hours (or even days) of computational time, also on powerful hardware parallel architectures. Thus, high-fidelity techniques can become prohibitive when we expect them t...

Wind farm modeling in a realistic environment using a multiscale approach

https://www.sintef.no/en/publications/publication/?pubid=CRIStin+1512028

We present a multiscale approach to model a windfarm under real meteorological conditions. The multiscale model consists of a mesoscale atmospheric code coupled to a stochastic ocean wave model, a microscale model and a super-microscale model. The mesoscale model (with 2.5km×2.5km horizontal resolut...

Effect of UNI- and bi-directional coupling of ocean-met interaction on significant wave height and local wind

https://www.sintef.no/en/publications/publication/?pubid=CRIStin+1512027

Accurate prediction of near surface wind and wave height are important for many offshore activities like fishing, boating, surfing, installation and maintenance of marine structures. The current work investigates the use of different methodologies to make accurate predictions of significant wave hei...

On interactions between wind turbines and the marine boundary layer

https://www.sintef.no/en/publications/publication/?pubid=CRIStin+1512026

Most mesoscale models are developed with grid resolution in the range of kilometers. Therefore, they may require spatial averaging to analyze flow behavior over the domain of interest. In doing so, certain important features of sub-grid scales are lost. Moreover, spatial averaging on the governing e...
