Abstract: This study evaluates how Reynolds-averaged Navier–Stokes (RANS) models perform in simulating the characteristics of mean three-dimensional perturbed flows in pipes with targeted wall-shapes. The principal objective of this ...

Abstract: Abstract. This study numerically investigates the impact of wall-based perturbation length on the response and recovery of turbulent pipe flow toward developing an effective passive flow manipulation system. The Reynolds ...

Abstract: The characteristics of blood flow in an abnormal pediatric aorta with an aortic coarctation and aortic arch narrowing are examined using direct numerical simulations and patient-specific boundary conditions. The blood flow ...
