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...

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...

A COMPUTATIONAL FRAMEWORK INVOLVING CFD AND DATA MINING TOOLS FOR ANALYZING DISEASE IN CAROTID ARTERY BIFURCATION

https://www.sintef.no/en/publications/publication/?pubid=CRIStin+1508337

Cardiovascular diseases, like Carotid Artery Disease and Coronary Artery Disease (CAD) are associated with the narrowing of artery due to build-up of fatty substances and cholesterol deposits (called plaque). Carotid Artery Disease increases the chances of brain stroke. Hence, the main objective of ...

Near wake region of an industrial scale wind turbine: comparing LES-ALM with LES-SMI simulations using data mining (POD)

https://www.sintef.no/en/publications/publication/?pubid=CRIStin+1477265

Accurate prediction of power generation capability needs proper assessment of blade loading and wake behavior. In this regard, the Sliding Mesh Interface (SMI) approach and the Actuator Line Model (ALM) are two diverse computational fluid dynamics (CFD) based approaches of simulating the turbine beh...

Wake modeling in complex terrain using a hybrid Eulerian-Lagrangian Split Solver

https://www.sintef.no/en/publications/publication/?pubid=CRIStin+1389182

Wake vortices (WVs) generated by aircraft are a source of risk to the following aircraft. The probability of WV related accidents increases in the vicinity of airport runways due to the shorter time of recovery after a WV encounter. Hence, solutions that can reduce the risk of WV encounters are need...

Spline based Mesh Generator for high fidelity simulation of flow around turbine blades

https://www.sintef.no/en/publications/publication/?pubid=CRIStin+1298993

Mesh generation involving complex geometries, such as wind turbine blades, is highly complicated. The problem is generally addressed using tetrahedral meshes, or hybrid meshes with hexahedral elements close to the body and tetrahedral elements elsewhere. The popularity of such mesh generators can be...
