Identification of cleaning mechanism by using neural networks

Computational fluid dynamics (CFD) modeling and application for cleaning of food‐contact surfaces: A review

“…This approach might significantly curtail development times (Hanisch et al, 2022). However, with the current technological landscape, simulating industrial-scale cleaning processes with a manageable computational burden remains unattainable (Golla et al, 2023). Compared with experimental results, the average cleaning rate of pipelines is often overestimated.…”

“…ML can further refine CFD in domains like turbulence modeling, formulating inflow boundary conditions, subgrid scale (SGS) models for LES, closure of RANS equations, crafting reduced order models (ROMs), and orchestrating flow control (Vinuesa & Brunton, 2022). Besides, a neural network‐based cleaning mechanism recognition algorithm, which can inform the choice of an apt cleaning model or spotlight areas where the cleaning mechanism diverges from anticipated behavior Golla et al (2023). Envisioning future research trajectories, harnessing ML for modeling and computations can substantially enhance model accuracy, revolutionizing the approach to food surface cleaning.…”

Aspects of image data preparation to extend a classification scheme for cleaning mechanisms to realistic soils

“…Simulation of cleaning processes would be a feasible approach for systematic variation of operating parameters with subject to reduce ecological and economical costs [6]. However, cleaning processes are very complex and often involve time-dependent material properties and turbulent multiphase flows [7]. A cost efficient way of conducting cleaning simulations of film-like soils with accuracies reasonable for industrial application is the Boundary Condition Cleaning Model (BCCM) approach, first introduced by Joppa et al [8].…”

“…However, the newer models no longer require solving a scalar transport equation, since soil removal is described differently. The way how this is done depends on the cleaning behavior of the soil, that is, the specific cleaning mechanism that is active in a particular situation [7]. Hence, knowledge about the cleaning mechanism is mandatory for the applicability of the aforementioned models.…”

“…Various authors distinguish soils according to their cleaning mechanism. A detailed discussion of the literature can be found in Golla et al [7]. The cleaning mechanisms considered in the present paper are based on the work of Köhler et al [11].…”
