Meta-Model-Based Calibration and Sensitivity Studies of Computational Fluid Dynamics Simulation of Jet Pumps

Abstract

Calibration and sensitivity studies in the computational fluid dynamics (CFD) simulation of process equipment such as the annular jet pump are suitable for design, analysis, and optimization. The application of CFD for such purposes is computationally intensive. Hence, an alternative approach with kriging-based meta-models was utilized. Calibration via the adjustment of two turbulent model parameters, Cμ and C2ε, and likewise two parameters in the simulation correlation for Cμ was considered, while sensitivity studies were based on Cμ as input. The meta-model-based calibration aids exploration of different parameter combinations. Computational time was also reduced with kriging-assisted sensitivity studies which investigated the effect of different Cμ values on pressure distribution.
