Computational fluid dynamics (CFD) models are oftenused to simulate and optimize BCRs. However, these models still requiread hoc adjustments of model parameters to anchor simulations to real-worldreactors. A recently proposed idea suggests that wall pressure fluctuationscould be exploited to obtain relevant closure models. In this work,we evaluated this idea for simulating BCRs. A published case of abubble column with 0.1 m diameter and 2 m height, for which the gasholdup and wall pressure fluctuation data were available, was considered.Three-dimensional transient flow in the BCR was simulated by usingthe Euler–Euler models. In the first step, following the conventionalapproach, the values of the key parameter (<em>C</em><sub>D</sub>/<em>d</em><sub>B</sub>) for estimating interphasedrag were obtained by matching simulated results with experimentalgas holdup data. An artificial neural network (ANN) was then trainedto relate experimental wall pressure fluctuations data with thoseof (<em>C</em><sub>D</sub>/<em>d</em><sub>B</sub>).The hybrid model demonstrated high accuracy, with an <em>R</em><sup>2</sup> of 0.99, and the predicted values fall within ±5%of the experimental data. The trained ANN was subsequently used toestimate the (<em>C</em><sub>D</sub>/<em>d</em><sub>B</sub>) for the cases unseen by the model. The wall pressure fluctuations-basedapproach successfully captured the influence of gas velocity on gasholdup for both the water and the 1.5% ethanol case. The approachwas also found to be reasonably successful for simulating the influenceof ethanol concentration on gas holdup. These findings demonstratethe feasibility of combining wall pressure fluctuations with machinelearning to estimate relevant model parameters. This work establishesa robust foundation for advancing the presented approach toward anchoringCFD models to real-world reactor systems.</p>","PeriodicalId":29804,"journal":{"name":"ACS Engineering Au","volume":"6 1","pages":"185–196"},"PeriodicalIF":9.0,"publicationDate":"2026-02-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147272082","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Variations in the chemistry of the base components (e.g., their polydispersities or ionic contents) require extensive off-line rheological analysis to ensure the products meet benchmarks for performance and thus consumer satisfaction. An in-line alternative for rheological quality control and monitoring thus has the potential to improve efficiency on industrial pipelines. Therefore, we demonstrate optical coherence tomography velocimetry (OCT-V) for the in-line processing of a shampoo based on SLES and CAPB with varying concentrations of salt. OCT-V is a noninvasive quasi-elastic light scattering technique, capable of spatially resolved velocity measurements with an axial depth resolution of 9 μm and a penetration depth of 1.5 mm into the samples. Our in-line apparatus uses infrared light (the wavelength is 1315 nm) and has been optimized for live manufacturing with a 200 L test rig at the Unilever R<i>&</i>D lab. The addition of salt to the shampoo is used for <i>in situ</i> formulation to increase the viscosity, inducing the spherical-to-wormlike micelle transition. To create in-line rheological benchmarks, we measured time averaged velocity profiles and transient velocity fluctuations in the shampoo formulations at imposed flow rates of <i>Q</i> = 500 and 1000 L/h.

Combined with measurement of the longitudinal pressure drop, this could be used to calculate constitutive properties, such as the viscosity.
