Numerical Simulation of 3D Flow Pattern at Open-Channel Junctions [PDF]
علوم و مهندسی آبیاری, 2011 This paper numerically investigates the 3D flow pattern at the 900 equal-width rectangular open channel junction. The Reynolds-Stress Model (RSM) is applied to simulate the turbulent flow. The flow is analyzed under steady-state conditions.

Influence of Test Temperature and Test Frequency on Fatigue Life of Aluminum Alloy EN AW‐2618A
Advanced Engineering Materials, EarlyView.The influence of test temperature and test frequency on the fatigue life of EN AW‐2618A is investigated. High‐cycle fatigue tests are performed at different test temperatures and frequencies on the 1000 h/230°C overaged state. Both test parameters reduce fatigue life due to time‐dependent damage mechanisms.

Advanced Engineering Materials, EarlyView.Different Al/Al bimetals with a single engineered interface reveal how mechanical mismatch governs fatigue crack growth under cyclic loading. Additionally, loading–unloading–reloading tests link the microyielding behavior to the fatigue crack growth resistance, while crack‐path analysis reveals toughening mechanisms at the interface, highlighting ...
