Analytical and numerical study of MHD natural convection in a horizontal shallow cavity with heat generation
Benos, L. T.; Kakarantzas, S. C.; Sarris, I. E.; Grecos, A. P.; Vlachos, N. S. (2014)A study is presented of two-dimensional MHD natural convection flow in an internally heated horizontal shallow cavity in the presence of an external uniform vertical magnetic field. The main feature of the present flow is ... -
Direct numerical simulation of a heat removal configuration for fusion blankets
Kakarantzas, S. C.; Grecos, A. P.; Vlachos, N. S.; Sarris, I. E.; Knaepen, B.; Carati, D. (2007)A series of direct numerical simulations (DNS) are performed to study the natural convection heat transfer between concentric cylinders at several Rayleigh and Hartmann numbers. The buoyant flow is driven by the temperature ... -
Magnetohydrodynamic natural convection in a vertical cylindrical cavity with sinusoidal upper wall temperature
Kakarantzas, S. C.; Sarris, I. E.; Grecos, A. P.; Vlachos, N. S. (2009)A series of numerical simulations were performed in order to study liquid metal MHD natural convection in a vertical cylindrical container with a sinusoidal temperature distribution at the upper wall and the other surfaces ... -
MHD natural convection in a laterally and volumetrically heated square cavity
Sarris, I. E.; Kakarantzas, S. C.; Grecos, A. P.; Vlachos, N. S. (2005)A numerical study is presented of unsteady two-dimensional natural convection of an electrically conducting fluid in a laterally and volumetrically heated square cavity under the influence of a magnetic field. The flow is ... -
Numerical modelling of rotating tangential layers (jets) in shells under strong uniform magnetic field
Fidaros, D. K.; Bühler, L.; Grecos, A. P.; Vlachos, N. S. (2010)A numerical study of tangential layers in steady-state magnetohydrodynamic rotating flows is presented using CFD to solve the inductionless governing equations. The analysis considers two basic flow configurations. In the ... -
On the limits of validity of the low magnetic Reynolds number approximation in MHD natural-convection heat transfer
Sarris, I. E.; Zikos, G. K.; Grecos, A. P.; Vlachos, N. S. (2006)In the majority of magnetohydrodynamic (MHD) natural-convection simulations, the Lorentz force due to the magnetic field is suppressed into a damping term resisting the fluid motion. The primary benefit of this hypothesis, ... -
Simulation of charged particle motion in a homogeneous magnetic field subject to a random force
Pantazis, S.; Valougeorgis, D.; Grecos, A. P. (2009) -
Statistical-mechanical description of classical test-particle dynamics in the presence of an external force field: modelling noise and damping from first principles
Kourakis, I.; Grecos, A. P. (2006)Aiming to establish a rigorous link between macroscopic random motion (described e.g. by Langevin-type theories) and microscopic dynamics, we have undertaken a kinetic-theoretical study of the dynamics of a classical ...
