This thesis presents the results of two 2-D computational studies of a circulation control Inlet Guide Vane (IGV) that takes advantage of the Coanda effect for flow vectoring. The IGV in this thesis is an uncambered airfoil that alters circulation around itself by means of a Coanda jet that exhausts along the IGV’s trailing edge surface.

Feb 10, 2021 · CFD is a complex technology involving strongly coupled non-linear partial differential equations which attempt to computationally model theoretical and experimental models in a discrete domain of complex geometric shape.

Mar 15, 2017 · 2D CFD simulations compared to experimental tow-tank data on the RVAT test model. The use of CFD with open-field-like boundaries is suggested. A reliable estimation of the turbine performance and the wake structure is obtained. The transitional turbulence model is recommended for low TSRs and/or small rotors.

Apr 4, 2023 · This study describes a computational fluid dynamics (CFD) analysis of a vertical axis wind turbine (VAWT) in two dimensions (2D). The study aims to investigate the performance and flow...

Numerical simulations are performed using a Reynolds-averaged Navier-Stokes (RANS) ow solver for a circulation control airfoil. 2D and 3D simulation results are compared to a circulation control wind tunnel test conducted at the NASA Langley …

Aug 19, 2024 · For a nominally two-dimensional flow case, as in the 2D bi-directional pressure gradient case from the Virginia Tech experiments, 2D CFD results can provide valuable data and insights at a fraction of the cost of simulating the entire flow.

Truncation Error (TE) acts as the local source for the transport of the discretization error (DE) in the domain. Mesh adaption based upon TE is performed for 1D and 2D Burgers equations. Examination of the analytically derived TE expressions in generalized coordinates provides insight into the effects of mesh quality on the DE.

2D Computational Fluid Dynamics (CFD) to generate airfoil tables to drive the Comprehensive Analysis (CA) code CAMRAD II [8,9]. CAMRAD II is a CA tool for rotorcraft [18] and has undergone extensive correlation of performance and loads measurements on rotorcraft, including coaxial rotors [19].

Jul 15, 2017 · Here simulation of flow through a rotating high solidity vertical axis wind turbine using OpenFOAM is shared. pimpleDyMFoam solver is used for the computation. The blade is operating at a tip speed ratio of 1.0. The blade cross section is based on NACA 0015 with a …
