,A High-Order Finite Volume Method for the Simulation of Phase Transition Flows Using the Navier–Stoons for the direct and accurate discretization of higher-order derivatives, which is particularly suitable for simulations on unstructured meshes. In this work, we show two numerical examples in which the interface is set to interact with great changes in the properties, in order to demonstrate the robustness of the method.

Simple Models for Cross Flow Turbines,tatistics of the generated wakes (time averaged velocities and Reynolds stresses). Subsequently, we compare the wakes resulting from simple models (a circular cylinder and an actuator disc) to the time averaged cross-flow turbine wakes. Additionally, we provide results for a reduced order model base

,Harmonic Balance Navier–Stokes Analysis of Tidal Stream Turbine Wave Loads,ted. One of its unique features is a harmonic balance solver enabling high–fidelity analyses of turbine periodic hydrodynamic loads with runtimes reduced by more than one order of magnitude over conventional time–domain CFD, and with negligible accuracy penalty. The strength of the new technology is

Analysis of the Aerodynamic Loads on a Wind Turbine in Off-Design Conditions,id dynamics (CFD) simulations. The turbulent wind flow is solved using an unsteady RANS approach and choosing the . model. Appropriate boundary conditions are used in combination with modified wall functions in order to preserve the atmoshperic boundary layer (ABL) profiles throughout the entire dom

An Algorithm for the Generation of Biofouled Surfaces for Applications in Marine Hydrodynamics,ver this type of surface roughness, marine biofouling has mainly been realized as ordered arrangements of roughness elements. These surfaces cannot be compared to realistic biofouled surfaces which show an irregular distribution of roughness features. In this work, a geometric algorithm for generati
