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
Analytic models of heterogenous magnetic fields for liquid metal flow simulations
Votyakov, E. V.; Kassinos, Stavros C.; AlbetsChico, X. (2009)A physically consistent approach is considered for defining an external magnetic field as needed in computational fluid dynamics problems involving magnetohydrodynamics (MHD). The approach results in simple analytical ...

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 ...

Article
Analyzing a turbulent pipe flow via the onepoint structure tensors: Vorticity crawlers and streak shadows
Stylianou, F. S.; Pecnik, R.; Kassinos, Stavros C. (2016)Efforts to identify and visualize nearwall structures typically focus on the region y+≳5, where largescale structures with significant turbulent kinetic energy content reside, such as the highspeed and lowspeed streaks ...

Application of a New Algebraic StructureBased Model to Rotating Turbulent Flows
Langer, C. A.; Kassinos, Stavros C.; Haire, S. L. (Elsevier, 2005)This chapter discusses application of a new algebraic structurebased model to rotating turbulent flows. A primary goal of Reynolds averaged NavierStokes (RANSbased modeling is to determine the Reynolds stress tensor in ...

ASBMBSL: An easy access to the structure based model technology
Aupoix, B.; Kassinos, Stavros C.; Langer, C. A. (2011)The Algebraic Structure Based Model (ASBM) offers unique features to represent the Reynolds stress tensor from the underlying turbulent structures. It is usually coupled with a non standard length scale equation. A way of ...

The ASBMSA turbulence closure: Taking advantage of structurebased modeling in current engineering CFD codes
Panagiotou, C. F.; Kassinos, Stavros C.; Aupoix, B. (2015)Structurebased turbulence models (SBM) carry information about the turbulence structure that is needed for the prediction of complex nonequilibrium flows. SBM have been successfully used to predict a number of canonical ...
