Characterization and application of vortex flow adsorption for simplification of biochemical product downstream processing
… an outer stationary cylindrical shell. Above a critical rotation rate, circular Couette flow bifurcates to a series of counter-rotating toroidal vortices. By suspending adsorbent resin in the vortices, a novel unit operation, vortex flow adsorption (VFA), is created. In VFA, the rotation of the …

Geometrically nonlinear configurations in rod-like structures
… uncovered, whereby the filament buckles above a critical rotation frequency. We then augment our experiments and simulations to include the effect of a no-slip rigid boundary on the locomotion of uni-flagellar bacteria. We find that the propulsive force is strongly affected by the presence of a …

Helical magnetorotational instability in MHD Taylor-Couette flow
Magnetorotational instability (MRI) is one of the most important and most common instabilities in astrophysics. Today it is widely accepted that it serves as a major source of turbulent viscosity in accretion disks, the most energy efficient objects in the universe. The importance of the MRI for …

Υπολογιστική σχετικιστική μελέτη των αστέρων νετρονίων με γενίκευση της μεθόδου των μετανευτωνείων προσεγγίσεων
Το κύριο αντικείμενο μελέτης της παρούσας διατριβής είναι τα σχετικιστικά πολυτροπικά μοντέλα περιστρεφόμενων αστέρων νετρονίων. Ο τελικός στόχος είναι να υπολογισθούν τα φυσικά χαρακτηριστικά ενός αστέρα νετρονίων στην περίπτωση της υδροστατικής ισορροπίας, της ομοιόμορφης περιστροφής με περαιτέρω …
