    <description descriptionType="Abstract">&lt;p&gt;Wall-resolved fluid-structure interaction (FSI) numerical simulations of the NREL 5 MW wind turbine blade&lt;br&gt;
are compared using two FSI approaches. The first method is based on high-fidelity Nektar++/SHARPy FSI framework,&lt;br&gt;
where the fluid governing equations are solved using high-order spectral/hp element method and the turbulent flow is&lt;br&gt;
resolved using Large Eddy Simulation (LES) on thick strips, while large-deformation dynamics of the structure are mod-&lt;br&gt;
elled using a geometrically exact nonlinear composite beam finite-element model. Thick strip method for the fluid reduces&lt;br&gt;
the computational cost by considering a series of smaller domains, each of which has a finite thickness in the spanwise&lt;br&gt;
direction. Hence, the overall flow over the blade is treated with a sectional approach, where in each of these sections,&lt;br&gt;
strips, the 3D flow is reconstructed locally. Tip-loss correction is used to compensate for the sectional approach over the&lt;br&gt;
blade. The second FSI approach is based on OpenFoam/Calculix coupling, where the second-order unstructured finite&lt;br&gt;
volume method approach is used for solving the three-dimensional flow equations and the flow turbulence is captured us-&lt;br&gt;
ing the k-&amp;omega; SST model. The structural dynamics are modeled via second-order finite element method using standard solid&lt;br&gt;
elements. Effects of the solution fidelity on the prediction of aerodynamic forces as well as on the full three-dimensional&lt;br&gt;
flow modelling over the blade versus sectional representation of flow over the blade while incorporating the local three-&lt;br&gt;
dimensionality in each section and tip-correction are discussed. Further, significance of two approaches on modelling&lt;br&gt;
the slender blade, one using the beam mode and the other utilizing the full 3D solution of structure is addressed. Finally,&lt;br&gt;
assessment of computational cost and scalability of the two approaches are presented and discussed.&lt;/p&gt;</description>
