Influence of axial spacing on stall development of FBCDZ-10-No20 mode contra-rotating fan

Meitan kexue jishu, 2023
The rotating fan is prone to instability such as stall and even surge when operating at low flow rates. In order to study the influence of axial spacings on the stall inception and its development and propagation process of a contra-rotating fan , a ...

Research on axial compression performance of concrete columns with angle steel embedded in BMSCC stay-in-place formwork

Case Studies in Construction Materials, 2023
A new type of stay-in-place formwork column (SFC) was proposed. The square prefabricated shell was made of basic magnesium sulfate cement based composite (BMSCC) and reinforced by angle steel frame. The SFC can be formed after ordinary concrete is poured.
