A New Approach to the Accretive Growth of Surfaces Via Hyperbolical Kinematics

Mathematical Methods in the Applied Sciences, Volume 48, Issue 16, Page 15349-15363, 15 November 2025.
ABSTRACT In the current work, we introduce the accretive growth of surfaces by using hyperbolical geometry. First, we describe hyperbolical kinematics along a generating curve to construct accretive surfaces having a hyperbolical cross‐section. The obtained surfaces are not only the ones having hyperbolical cross‐sections but also their material points

Performance Enhancement of a Low-Pressure Ratio Centrifugal Compressor Stage with a Rotating Vaneless Diffuser by Impeller Disk Extended Shrouds

Journal of Applied Fluid Mechanics, 2016
Numerical simulations have been carried out to examine the performance and flow parameters of forced rotating vaneless diffuser obtained by the extension of impeller disks of a low-pressure ratio shrouded type centrifugal compressor stage with diffuser ...

Comparative study on the complex behaviour of flow fields in a transparent non-axisymmetric corotating system between two arm-insertion angles at two measurement planes in an enclosure

Journal of Fluid Science and Technology
Flow driven by co-rotating disks, such as hard disk drives (HDD) have been studied in previous research using axisymmetric models. In our work, a unique non-axisymmetric 3.5" transparent HDD model for information storage was used to investigate the ...

The Influence of Swirl Brakes on the Rotordynamic Forces Generated by Discharge-to-Suction Leakage Flows in Centrifugal Pumps [PDF]

, 1993
Increasing interest has been give to swirl brakes as a means of reducing destabilizing rotordynamic forces due to leakage flows in new high speed rocket turbopumps.

A Theoretical Study of Ingress for Shrouded Rotating Disk Systems With Radial Outflow [PDF]

Journal of Turbomachinery, 1989
Sealing of the cavity formed between a stationary disk and a rotating disk under axisymmetric conditions is considered. A mathematical model of the flow in the cavity based on momentum integral methods is described and this is coupled to a simple model of the seal for the case when no ingress occurs.

Diplomat and International Worker Mobilities: A Family Lens on Power Dynamics

Population, Space and Place, Volume 31, Issue 7, October 2025.
ABSTRACT This article applies a family lens to power relations experienced by families of diplomats and international workers during frequent relocations. The life‐making practices of families are crucial for intergenerational well‐being as well as these workers' international assignments.

Who cares? The legal (non)recognition of caregiving by single and childfree aunts in Taiwan

Family Court Review, Volume 63, Issue 4, Page 745-765, October 2025.
Abstract Aunts remain the “forgotten kin” in family and kinship care studies, which largely center on parenthood and coupledom. Existing literature tends to subsume them under the broad category of extended family members, devoting scant scholarly attention to aunthood as a distinct category or to the relationship between aunthood and the law.
