Explanation :
Strainers are used in processing plants and chemical industry as a filtering device. The filtration process involves flow through narrow passages, which causes high pressure drop or head-loss. Besides the losses in filter screens, there are other component of head loss such as during entry and exit pipes, also due to expansion and contraction at junctions. Theoretically, pressure drops increase non-linearly with increasing flow rates. Computational Fluid Dynamics (CFD) is useful to understand the cause of pressure drops in industrial strainers.
In this case-study, the pressure drops across various locations of an off-line basket strainer for different strainers is determined using CFD analysis. The study is carried for a basket strainer with perforated sheet with wire mesh.
Challenges
Modeling the porous zone for the perforated sheet and wire mesh.
Finding the Darcy and Forchheimer coefficients for the porous zone.
Finding the correct turbulence model.
Maintaining the Y+ value.
