ASSESSMENT OF THE CAPABILITY OF AVAILABLE METHODS OF FLOW FIELD NUMERICAL MODELLING ON THE EXAMPLE OF AIR FLOW THROUGH A CHANNEL WITH A CIRCULAR BUMP

TASK Quarterly, 2017
This paper is an attempt at a systematic approach to the flow field analysis in the case of air flowing through a straight channel with a circular bump. The results of the authors’ own experimental measurements are compared to those obtained by means of

Comparative Numerical Studies for the Flow Energy Dissipation Features in a Vertical Two‐Stage Centrifugal Pump in Pump and Turbine Conditions

Energy Science &Engineering, Volume 14, Issue 2, Page 764-779, February 2026.
Based on entropy theory, this study presents a comparative numerical analysis of the flow energy dissipation (FED) in a VTSP under two distinct operating conditions: pump condition and turbine condition, both characterized by relatively high hydraulic efficiencies of 88.9% and 87.4%, respectively. In pump condition, the highest FED production occurs in

In Vitro Hemocompatibility of the BiVACOR Total Artificial Heart in Continuous and Pulsatile Flow

Artificial Organs, Volume 50, Issue 1, Page 84-93, January 2026.
BiVACOR's total artificial heart generates remarkably similar hemocompatibility when operated with a pulse or during continuous flow. Under both conditions, hemolysis and von Willebrand Factor multimers were similar to a commercial reference device after 6 h in vitro evaluation.

Composite seal for turbomachinery [PDF]

, 1979
A gas path seal suitable for use with a turbine engine or compressor is provided. A shroud wearable or abradable by the abrasion of the rotor blades of the turbine or compressor protects the rotor blades. A compliant backing surrounds the shroud.

Brazing Temperature‐Dependent Cracking in Inconel 625/BNi‐2/Hastelloy X Brazed Junctions

Advances in Materials Science and Engineering, Volume 2026, Issue 1, 2026.
Inconel 625 and Hastelloy X are two commonly used solid‐solution‐strengthened superalloys, and the connection of them is inevitable in high‐temperature applications. Brazing is a commonly accepted joining method. In this study, the two alloys were vacuum brazed by sandwiching a BNi‐2 adhesive filler into them.
