Vertical upward flow patterns in small diameter tubes [PDF]

, 2005
Two-phase flow patterns were studied in vertical small diameter tubes using R134a as the working fluid. The observed flow patterns include bubbly, dispersed bubble, confined bubble, slug, churn, annular and mist flow.

Recovering the Internal Dynamics and the Shapes of Galaxy Clusters: Virgo Cluster [PDF]

, 2001
We describe a method for recovering of the substructure, internal dynamics and geometrical shapes of clusters of galaxies. Applying the method to the Virgo cluster, we, first, reveal the substructure of the central 4 arc degree field of the Virgo cluster

Steady-State Flow Characteristics and End Clearance Optimization of Internal Gear Grease Pump

Advances in Materials Science and Engineering, 2021
The internal gear grease pump is a mechanical device used for transfer of high viscosity fluid. The existing clearance between the end faces of the internal or external gear and the floating side plate might cause pump leakage during operation.

Internal-external flow integration for a thin ejector-flapped wing section [PDF]

, 1979
Thin airfoil theories of an ejector flapped wing section are reviewed. The global matching of the external airfoil flow with the ejector internal flow and the overall ejector flapped wing section aerodynamic performance are examined.
