Abstract: The performance and stable operating range of compressors are critical for the efficient operation of various turbomachinery systems. To reveal the flow instability mechanism of a high-speed and high-loaded compressor, a ...

Abstract: This paper compares the difference and accuracy of bursting pressure prediction based on the flow stress σf prediction method, plastic collapse prediction method, and ductile damage model prediction method in Inconel 690 ...

Abstract: Charpy impact specimens are preferred to characterize the deterioration of steel in irradiation surveillance program in nuclear industry. But the fracture toughness cannot be acquired by the Charpy impact experiment directly. ...

Abstract: In this paper, a minimum toughness assessment method of exempting postweld heat treatment (PWHT) based on the master curve method is proposed to replace the current method of determining whether to perform PWHT by material ...

Abstract: Rupture disk safety device plays an important role as the last safety barrier to prevent catastrophic overpressure in chemical vessels. In this article, a burst pressure calculation method of ultrahigh pressure rupture ...

Abstract: Sand and gravel mining from riverbeds is a major supply of construction materials. A mining pit in a riverbed is very unstable and subject to scouring and deposition, which results in migration of the pit. A series of ...

Abstract: Hydrogenation reactor services as key equipment in chemical and energy industries. Manufacturing processes of hydrogenation reactor changes its performance before long-term service but impact of manufacturing residual ...
