On the Force Decompositions of Lighthill and Morison

Modelling Pressurized Water Reactor cores in terms of porous media

“…This approach is in good agreement with experiments and has been used in many subsequent studies (Zhou and Graham, 2000;Sarpkaya, 2001). For an axial flow, Paı¨doussis (1966) proposed an expression for the fluid forces acting on the slender body.…”

A brief review of recent results in vortex-induced vibrations

“…They provide a proof for the validity of the decomposition of the force in a general viscous flow. Sarpkaya (2001) made a contrasting conclusion, stating that ''Lighthill's assertion that the viscous drag force and the inviscid inertia force acting on a bluff body immersed in a time-dependent flow operate independently, is not in conformity with the existing exact solutions and experimental facts''. Sarpkaya quoted an exact solution given in a really famous paper by Stokes (1851) concerning the force F(t) on an oscillating sphere in a viscous fluid, valid for small amplitude.…”

Numerical simulation of flow around an orbiting cylinder at different ellipticity values

“…Oscillatory flow has been fairly widely researched [e.g., Bearman et al (1995), Sarpkaya (1986Sarpkaya ( , 2001), Chaplin and Subbiah (1996)]. Orbital flow, in which the fluid particles follow a closed orbit, has been investigated among others by Chen et al (1995), who modelled the flow about a stationary horizontal cylinder placed in an orbital flow.…”
