Experimental research of pulsation pressure and hydrodynamic noise at the bow of underwater vehicle
Xibei Gongye Daxue XuebaoThe design of the bow of the underwater vehicle affects its hydrodynamic performance, and a better design can reduce the direct impact of water on the bow and thus reduce the hydrodynamic noise of the underwater vehicle.

Low‐Angle Grain Boundaries and Re‐Segregation in Single‐Crystalline Ni‐Base Superalloys
Advanced Engineering Materials, EarlyView.This work demonstrates that Re‐segregation at low‐angle grain boundaries (LAGBs) in Ni‐base superalloys is influenced by misorientation angle. Advanced microscopy and atom probe tomography reveal that higher misorientation angles increases Re‐segregation.

Surface Tension Measurement of Ti‐6Al‐4V by Falling Droplet Method in Oxygen‐Free Atmosphere
Advanced Engineering Materials, EarlyView.In this article, the temperature‐dependent surface tension of free falling, oscillating Ti‐6Al‐4V droplets is investigated in both argon and monosilane doped, oxygen‐free atmosphere. Droplet temperature and oscillation are captured with one single high‐speed camera, and the surface tension is calculated with Rayleigh's formula.

Classical Cepheid Pulsation Models: IX. New Input Physics
, 2003 We constructed several sequences of classical Cepheid envelope models at solar chemical composition ($Y=0.28, Z=0.02$) to investigate the dependence of the pulsation properties predicted by linear and nonlinear hydrodynamical models on input physics.

Simulation of Pressure Pulsations
, 2020 Utmattelsesbelastning er den primære årsaken til turbinskade i vannkraftverk. Syklisk belastning fra trykkpulsasjoner kan forårsake slik utmattelsesbelastning. Tilegning av informasjon om trykkpulsasjoner, og samspillet mellom turbin og vannvei, kan bidra til å unngå tidlig svikt i turbinene. Fenomenet kan studeres gjennom feltmålinger, men å utføre og
