  • Direct numerical simulation of a fully developed turbulent square duct flow up to Re-tau=1200 

    Zhang, Hao; Trias Miquel, Francesc Xavier; Gorobets, Andrey; Tan, Yuanqiang; Oliva Llena, Asensio (2015-08-01)
    Article
    Open Access
    Various fundamental studies based on a turbulent duct flow have gained popularity including heat transfer, magnetohydrodynamics as well as particle-laden transportation. An accurate prediction on the turbulent flow field ...
  • Direct numerical simulation of backward-facing step flow at Ret = 395 and expansion ratio 2 

    Pont Vilchez, Arnau; Trias Miquel, Francesc Xavier; Gorobets, Andrey; Oliva Llena, Asensio (2019-03-25)
    Article
    Open Access
    Backward-facing step (BFS) constitutes a canonical configuration to study wallbounded flows subject to massive expansions produced by abrupt changes in geometry. Recirculation flow regions are common in this type of flow, ...
