The finite volume immersed boundary method (feedback forcing-based), along with semi-implicit strategy, is incorporated to create a computational model. The control force is applied in the direction against the fluid flow, to control the equilibrium position and drive it to the channel center. The effect of the Reynolds number, particle diameter and density ratio on the control force is studied. From parametric studies, a prediction model is developed for the control force with the Reynolds number, particle diameter and density ratio as inputs. The linear regression methodology in machine learning is utilized to create the prediction model. The predicted values of control force are observed to match those of the simulation results. © 2023 Taylor & Francis Group, LLC.ForecastingParticle sizePosition controlTurbulent flowControl forceDensity ratioDiameter ratioEquilibrium positionsInertial migrationParticle densitiesParticle diametersPoiseuille flowPrediction modellingReynold numberReynolds numberarticlecomputer modelfluid flowlinear regression analysismachine learningpredictionsimulation
