“…With increasing Reynolds number, the transition moves upstream, closer to the leading edge. Vortices generated in the transitional area were clearly shorter compared to regimes with Reynolds number Re2is = 2.5×10 5 .…”

“…Therefore several BL transition models were developed and are widely tested in various examples by Straka et al [3,4], Menter et al [5], Suzen and Huang [6] or Steelant and Dick [7]. To validate the CFD models it is necessary to have the relevant experimental data of the BL transition for the different flow conditions.…”

“…A transition model suggested by Menter et al [8] is based on correlation-based approach which appears to provide consistent results. This model has been applied to a number of two-(2D) and three-dimensional (3D) test §ow cases [9] and simulations agreed well with experiments for the studied cases at a wide range of Reynolds numbers and freestream turbulent intensities.…”

Prediction of laminar turbulent transition at high level of free-stream turbulence in boundary layers of airfoil geometries with external pressure gradient changeover is in focus. The aim is a validation of a transition model for transition prediction in turbomachinery applications. Numerical simulations have been performed by using a transition model by Langtry and Menter for a number of di¨erent cases of pressure gradient, at Reynolds-number range, based on the airfoil chord, 50 000 ≤ Re ≤ 500 000, and free-stream turbulence intensities 2% and 4%. The validation of the computational results against the experimental data showed good performance of used turbulence model for all test cases.

“…The former variable is used to trigger transition, whilst the latter is solved to set the transition onset criteria (ANSYS, 2012). This model has been extensively validated with experiments for a range of transitional flows (including turbomachinery applications) in works such as Menter et al (2004), Langtry et al (2004), Langtry and Menter (2005), Völker (2006), and.…”

(2017) Numerical investigation of the effect of viscosity in a multistage electric submersible pump, Engineering Applications of Computational Fluid Mechanics, 11:1, 258-272, DOI: 10.1080/19942060.2017 ABSTRACTElectric submersible pump (ESP) systems are commonly used as an artificial lift technique by the petroleum industry. Operations of ESPs in oil wells are subjected to performance degradation due to the effect of oil viscosity. To understand this effect a numerical study to simulate the flow in three stages of a multistage mixed-flow type ESP operating with a wide range of fluid viscosities, flow rates, and rotational speeds was conducted. The problem was solved by using a commercial computational fluid dynamics (CFD) software. The numerical model was validated with experimental head curves from the literature at different viscosities and rotational speeds available for the same ESP model used in this study, and good agreement was found. Performance degradation was evaluated by analyzing the effect of viscosity on head and flow rate. In addition, a flow field analysis to compare the flow behavior when the pump operates at different viscosities was carried out. The interaction between stages was also analyzed, and the influence of a previous stage on the upstream flow was evidenced. The flow field was analyzed at a curved surface that follows the complex mixed-flow geometry of the stages. CFD proved to be useful for exploring this kind of feature, a task whose accomplishment by means of experimental methods is not trivial. Such analysis helps to understand the flow pattern behind head and flow rate degradation when the Reynolds number is decreased. The results from this work are helpful as they provide a basis to estimate performance degradation for general scenarios. ARTICLE HISTORY
