Comparative analysis of turbulence model influence in numerical simulation of an experimental radial compressor stage

open access: yesВестник Самарского университета: Аэрокосмическая техника, технологии и машиностроение, 2023
The accuracy of a CFD model of a turbo-machine might depend on a number of factors: turbulence model, quality of the mesh model, boundary conditions, solver settings, consideration of secondary geometric factors, etc.

Centrifuge model testing for pile foundation reuse [PDF]

open access: yesInternational Journal of Physical Modelling in Geotechnics, 2011
With continuous development in the urban environment, the ground is becoming increasingly congested with redundant foundations. The underground development of services and infrastructure already restricts the location of new building foundations and the redundant foundations only add to this problem.

Study on distribution of sidewall earth pressure on open caissons considering soil arching effect

open access: yesScientific Reports, 2023
Based on the soil arching effect theory, the magnitude and distribution of sidewall earth pressure on open caissons when the embedded depth is large was analyzed by using theory of non-limit state earth pressure theory and horizontal differential element

Development of a stereovision-based technique to measure the spread patterns of granular fertilizer spreaders [PDF]

open access: yes, 2017
Centrifugal fertilizer spreaders are by far the most commonly used granular fertilizer spreader type in Europe. Their spread pattern however is error-prone, potentially leading to an undesired distribution of particles in the field and losses out of the ...
