Image source: IADC

International Association of Dredging Companies (IADC) recently released a new article titled “Numerical investigation of the head and unsteady flow characteristics of a dredge pump loading high-concentration sands”.

The article presents research which numerically simulates the unsteady water flow and silt-laden flow in a dredge pump and comparatively analyses the unsteady characteristics of the pump performance and the flow field in three typical conditions to expound the influence of sands and the relationship between head and flow field.

The research object is a three-blade dredge pump and the calculation domain includes a suction pipe, an impeller, a volute casing and two sidewall gaps beside the impeller shrouds.

Auhthors of the article are Cao Lei (R&D Engineer at CCCC National Engineering Research Center of Dredging Technology and Equipment CO. LTD), Wang Zheng-wei (Professor in the Department of Energy and Power Engineering at Tsinghua University), and Zheng Lin-zhu (Director of the Equipment Design & Research Institute, CCCC National Engineering Research Center of Dredging Technology and Equipment CO. LTD.)
