An efficient spectral code for incompressible flows in cylindrical geometries
Mercader Calvo, María Isabel; Batiste Boleda, Oriol; Alonso Maleta, María Aránzazu (2010-02)
Article
Restricted access - publisher's policyAn efficient and accurate numerical scheme is proposed to solve the incompressible Navier–Stokes equations in a bounded cylinder. The scheme is based on a projection method formulated in primitive variables to maintain the ... -
