RISThe Relation between the Tibetan Winter Snow and the Asian Summer Monsoon and Rainfall: An Observational Investigation
Publisher: American Meteorological Society
Abstract: Utilizing winter (November?March) accumulated snow depth data at 60 stations over the Tibetan Plateau (TP) for the period 1960?98, three typical patterns of the TP snow anomaly's spatial distribution were objectively ...
Investigation on a Type of Flow Control to Weaken Unsteady Separated Flows by Unsteady Excitation in Axial Flow Compressors
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: By solving unsteady Reynolds-averaged Navier-Stokes equations discretized by a high-order scheme, the results showed that the disordered unsteady separated flow could be effectively controlled by ...
Reducing Full-Field Residual Stress of Girth Weld With Thick Wall by Combining Local PWHT and Water Jet Peening
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, a new controlling method combined local postweld heat treatment (PWHT) and water jet peening (WJP) was proposed to reduce full-field residual stress of girth weld with thick wall. The finite element analysis ...
Probability of Failure Associated with Design and Safety Factors for Intact and Corroded Pipes under Internal Pressure
Publisher: ASCE
Abstract: The assessment of reliability levels associated with the design and safety factors (DFs and SFs) is important for modern pipeline engineering to achieve probabilistic design using a conventional deterministic format. To ...
Probabilistic Analysis of Pipelines in Geohazard Zones Using a Novel Approach for Strain Calculation
Publisher: ASCE
Abstract: This paper presents an approach for probabilistic analysis of pipelines buried through geohazard-prone areas that induce permanent ground movements potentially. In this approach, an easy-to-implement response prediction ...
