Travelling-waves consistent with turbulence-driven secondary flow in a square duct [PDF]
, 2010 We present numerically determined travelling-wave solutions for pressure-driven flow through a straight duct with a square cross-section. This family of solutions represents typical coherent structures (a staggered array of counter-rotating streamwise ...

Numerical simulation of a supersonic ejector for vacuum generation with explicit and implicit solver in openfoam [PDF]
, 2019 Supersonic ejectors are used extensively in all kind of applications: compression of refrigerants in cooling systems, pumping of volatile fluids or in vacuum generation. In vacuum generation, also known as zero-secondary flow, the ejector has a transient

Flow structure of the confluence between an open channel and a pipe
Water Science and Technology, 2023 It is common that the sewage is discharged into rivers through a municipal drainage network. The hydraulic properties of the confluence between a lateral drainage pipe and a rectangular open channel are investigated using numerical simulation.

Stability of an Axisymmetric Liquid Metal Flow Driven by a Multi-Pole Rotating Magnetic Field
Fluids, 2019 The stability of an electrically conducting fluid flow in a cylinder driven by a multi-pole rotating magnetic field is numerically studied. A time-averaged Lorentz force term including the electric potential is derived on the condition that the skin ...

Compressibility Effects on Secondary Flows [PDF]
Journal of the Aeronautical Sciences, 1956 The method of W. R. Hawthorne for the calculation of the secondary vorticity is generalized for compressible flow. It is shown that in the linearized theory (small vorticity) the influence of compressibility upon the secondary vorticity is due to (1) the entropy gradient in the approaching flow and (2) the compression of the fluid during the ...

New Insights into Flow for a Low-Bypass-Ratio Transonic Fan with Optimized Rotor
Energies, 2023 In this paper, a three-dimensional aerodynamics optimization system is built and applied to optimize a rotor blade to balance the conflicts between stall margin, total pressure ratio, adiabatic efficiency, and mass flow rate for the high-loading and ...
