Article
Advances in particle representation modeling of homogeneous turbulence. From the linear PRM version to the interacting viscoelastic IPRM
Kassinos, Stavros C.; Akylas, Evaggelos (2012)In simple flows with mild mean deformation rates the Reynolds stresses are determined by the strain rate. On the other hand, when the mean deformation is very rapid, the turbulent structure takes some time to respond and ...

Article
An analytical solution for rapidly distorted turbulent shear flow in a rotating frame
Akylas, Evaggelos; Kassinos, Stavros C.; Langer, A. C. (2006)In this study we apply rapid distortion theory to the case of nonstratified homogeneous turbulence that is sheared in a frame that counterrotates at a rate that matches in magnitude the rotation associated with the mean ...

Effects of selective water withdrawal schemes on thermal stratification in Kouris Dam in Cyprus
Ma, Shengwei; Kassinos, Stavros C.; FattaKassinos, Despo; Akylas, Evaggelos (2008)Thermal stratification and its seasonal variations in Kouris Dam in Cyprus were simulated, and the impact of five different water withdrawal schemes was studied, using the 2D, laterally averaged CEQUALW2 reservoir model. ...

Linear analysis of generalized turbulent hyperbolic flow in a rotating frame
Langer, C. A.; Akylas, Evaggelos; Kassinos, Stavros C. (2007)We apply inviscid rapid distortion theory to the generalized case of turbulent hyperbolic flow in a rotating frame and investigate the dependence of the evolution of the turbulent kinetic energy on the frame rotation rate. ...

Article
On the linear stability of turbulent plane strain flow in a rotating frame
Akylas, Evaggelos; Langer, C. A.; Kassinos, Stavros C.; Demosthenous, E. (2007)We apply inviscid rapid distortion theory to the limiting hyperbolic case of turbulent plain strain flow in a rotating frame and investigate the dependence of the evolution of the turbulent kinetic energy on the frame ...

Article
Rapid shear of initially anisotropic turbulence in a rotating frame?
Akylas, Evaggelos; Kassinos, Stavros C.; Langer, C. A. (2007)In the present study, we investigate, using inviscid rapid distortion theory, the evolution of sheared turbulence in a rotating frame as a function of the rotation rate (including stable, transitional, and unstable regimes), ...

Article
Rapidly sheared homogeneous stratified turbulence in a rotating frame
Kassinos, Stavros C.; Akylas, Evaggelos; Langer, C. A. (2007)Rapid distortion theory is applied to stratified homogeneous turbulence that is sheared in a rotating frame. Insight into the stabilizing and destabilizing effects of the combined stratification and frame rotation is gained ...
