Direct numerical simulation of supersonic pipe flow at moderate Reynolds number

Davide Modesti, Sergio Pirozzoli

We study compressible turbulent flow in a circular pipe, at computationally high Reynolds number. Classical related issues are addressed and discussed in light of the DNS data, inc…

Direct numerical simulation of conical shock wave/turbulent boundary layer interaction

Feng-Yuan Zuo, Antonio Memmolo, Guo-ping Huang +1

Direct numerical simulation of the Navier-Stokes equations is carried out to investigate the interaction of a conical shock wave with a turbulent boundary layer developing over a f…

Direct numerical simulation of developed compressible flow in square ducts

Davide Modesti, Sergio Pirozzoli, Francesco Grasso

We carry out direct numerical simulation of compressible square duct flow in the range of bulk Mach numbers M_b = 0.2-3, and up to friction Reynolds number Re_τ = 500. The effects…

Numerically stable formulations of convective terms for turbulent compressible flows

Gennaro Coppola, Francesco Capuano, Sergio Pirozzoli +1

A systematic analysis of the discrete conservation properties of non-dissipative, central-difference approximations of the compressible Navier-Stokes equations is reported. A gener…

On turbulent friction in straight ducts with complex cross section: the wall law and the hydraulic diameter

Sergio Pirozzoli

We develop predictive formulas for friction resistance in ducts with complex cross-sectional shape based on the use of the log law and neglect of wall shear stress nonuniformities.…

On the role of secondary motions in turbulent square duct flow

Davide Modesti, Sergio Pirozzoli, Paolo Orlandi +1

We use a direct numerical simulations (DNS) database for turbulent flow in a square duct up to bulk Reynolds number $\Rey_b=40000$, to quantitatively analyze the role of secondary…
