Interstellar Turbulence I: Observations and Processes
Annual Review of Astronomy and Astrophysics, 2004 This two-part review summarizes interstellar turbulence and its implications. The first part begins with diagnostics and energy sources. Turbulence theory is considered in detail, including the basic fluid equations, solenoidal and compressible modes ...

Hybrid Computation of the Aerodynamic Noise Radiated by the Wake of a Subsonic Cylinder
Fluids, 2023 The noise radiated by the flow around a cylinder in the subcritical regime at ReD=1×104 and at a subsonic Mach number of M=0.5 is here studied. The aerodynamic sound radiated by a cylinder has been studied with a wide range of Reynolds numbers, but there
