The interface Halo-Cell sliding mesh approach simplifies the coding, specially in 3D, since it only requires the construction of a single halo cell, instead of the standard methodologies that require the computation of intersections between non edges (2D) or faces (3D) of the nonconforming elements at the interface. Note that this method does not assure mass conservation. However, in the numerical tests we have observed that the magnitude of the conservation error is below the magnitude of the error in the variables, and the order of convergence is at least the same than for the variables.

The disadvantage of RANS models is that the flow is temporally averaged and thus unsteady vortices shed off turbine blades are damped and their influence reduced. Large-Eddy Simulations achieve a more accurate representation of the instantaneous flow [14, 18], which appears to be critical for VATT simulations, because the downstream side of a VATT is affected significantly by the vortices shed on the upstream side. In all above-mentioned studies, the sliding mesh technique is used to represent the movement of the blades in relation to the fixed Eulerian fluid mesh.
