Study on the hydrodynamic coefficients of the nettings [PDF]
Bulletin of the Korean society of Fisheries Technology, 2009 In this study, the hydrodynamic coefficients were measured using various nettings to analyze the change of drag coefficients and lift coefficients as a basic study for deriving hydrodynamic coefficients. The data on hydrodynamic force obtained from the flume tank tests were used to compare and analyze the hydrodynamic coefficients based on Reynolds ...

Hydrodynamics and transport coefficients for dilute granular gases [PDF]
Physical Review E, 2003 The hydrodynamics of granular gases of viscoelastic particles, whose collision is described by an impact-velocity dependent coefficient of restitution, which is developed using the Chapman-Enskog approach. We derive the hydrodynamic equations and the according transport coefficients with the assumption that the shape of the velocity distribution ...
