Influence of inlet velocity condition on unsteady flow characteristics in piping with a short elbow under a high-Reynolds-number condition

open access: yesMechanical Engineering Journal, 2017
In the design of the Advanced Sodium-cooled Fast Reactor in Japan, the mean velocity of the coolant is approximately 9 m/s in the primary hot leg (H/L) piping, which has a diameter of 1.27 m.

A Computational Fluid Dynamics Study on Characteristics of Flow Separation in Flow Rate Measurement Using Multi-Hole Plates

open access: yesEngineering Proceedings, 2023
Flow rate measurement is a challenging task in the industry as there is no general-purpose measuring instrument for all appliances. However, orifice plates with multiple holes can be employed to measure the flow rate accurately.

CFD Modeling of Hydrocyclones—A Study of Efficiency of Hydrodynamic Reservoirs

open access: yesFluids, 2020
The dynamics of hydrocyclones is complex, because it is a multiphase flow problem that involves interaction between a discrete phase and multiple continuum phases. The performance of hydrocyclones is evaluated by using Computational Fluid Dynamics (CFD),

Model-Based Analysis of Flow Separation Control in a Curved Diffuser by a Vibration Wall

open access: yesEnergies, 2021
Vibration wall control is an important active flow control technique studied by many researchers. Although current researches have shown that the control performance is greatly affected by the frequency and amplitude of the vibration wall, the mechanism ...

Phase Separation Driven by Active Flows

open access: yesPhysical Review Letters, 2023
We extend the continuum theories of active nematohydrodynamics to model a two-fluid mixture with separate velocity fields for each fluid component, coupled through a viscous drag. The model is used to study an active nematic fluid, mixed with an isotropic fluid.

Effects of flow rate ratio on loss reduction of T-junction pipe

open access: yesJournal of Fluid Science and Technology, 2014
T-junction pipes are frequently used in industrial facilities to split one flow into two flows or to merge two flows into one flow. In the counter-flow type of confluence in this type of pipe, separated vortex flow regions are formed near the junction ...

Effects of contraction ratio on loss reduction of the flow in the reducing elbow duct with a weir-shaped obstacle

open access: yesJournal of Fluid Science and Technology, 2023
90-degree elbow pipe/duct is one of the piping element which is used frequently in industrial apparatus. The separated flow which occurs at inner corner of elbow part and the secondary flow which occurs at the elbow and its downstream cause significant ...
