Low-Mach number treatment for Finite-Volume schemes on unstructured meshes

“…The interface fluxes are computed based on the boundary extrapolated reconstructed values, which are obtained by a polynomial reconstruction from element-averaged data. The spatial discretisation is based on the approach of [8,9] and lies in the the k-exact least square reconstruction, which is suitable for unstructured meshes with various types of element shapes in 2D and 3D, and it has been previously used successfully for laminar, transitional and turbulent flows [13,[46][47][48][49][50][51][52][53] and all the schemes are implemented in the UCNS3D CFD code as detailed in [52]. Therefore, only the key characteristics of this approach are going to be described in this paper.…”

Computational modelling of a solid and deformed automotive rotating wheel in contact with the ground

“…High-order discretisation ( > 2 nd - order ) for vortex-dominant flows enhances accuracy and potential efficiency of the overall numerical method. 41…”

“…2nd-order) for vortex-dominant flows enhances accuracy and potential efficiency of the overall numerical method. 41 The CFD model consists of a rotating wheel equivalent to the conditions as in Fackrell's 9 experiment. The flow around the wheel is simulated with a Reynolds number of Re d = 5:3 Á 10 5 based on the wheel diameter.…”

An iterative near-boundary reconstruction strategy for unstructured finite volume method

“…Despite the fact that unstructured high-order finite volume methods (FVM) have been very promising and popular in the computational fluid dynamics (CFD) research community [1,2,3,4], the second-order FVM is still a prominent and dominating numerical method for simulating complex flows in both scientific and industrial scenarios, and it is still developing with much effort, aiming at further improvements regarding both accurate approximation and/or computational efficiency. An extensive overview of unstructured FVM discretizations and solvers was given by Mavriplis [5].…”
