Effect of Reynolds Number and Mach Number on flow angularity probe sensitivity [PDF]

Preliminary calibrations were performed on nine flow angularity probes in the Langley 7- by 10-Foot High-Speed Tunnel (7 x 10 HST) and the Langley 0.3-Meter Transonic Cryogenic Tunnel (0.3-m TCT).

The influence law of process parammeters on end concavity of hexahedral blank cross wedge rolling (CWR)

Metalurgija, 2020
In order to expand the range of the cross wedge rolling (CWR) product, realize CWR of hexahedral blank. In this paper, the three-dimensional Finite element model (FEM) of hexahedral blank CWR is established by DEFORM finite element software.

Inflation Dynamics [PDF]

This paper first outlines the key stylized facts about changes in inflation dynamics in recent years: 1) inflation persistence has declined, 2) the Phillips curve has flattened, and 3) inflation has become less responsive to other shocks.

Numerical analysis of the cross wedge rolling process (CWR) for a stepped shaft

Metalurgija, 2015
The paper presents the results of numerical modeling of a complex CWR process for producing a stepped shaft. The modeling was performed using the Finite Element Method (FEM) based commercial software Simufact.Forming.
