Self Oscillation of Underexpanded Impinging Jet with Annular flow

Hybrid RANS/LES computation of plane impinging jet flow

Flow characteristics are presented of simulation results of plane impinging jets at high nozzle-plate distances, with two k-ω based hybrid RANS/LES (Reynolds Averaged Navier–Stokes/Large–Eddy Simulation) models and a k-ω RANS model. The first hybrid RANS/LES model is obtained by substitution of the turbulent length scale by the local grid size in the destruction term of the turbulent kinetic en...

Krypton tagging velocimetry of an underexpanded jet.

In this work, we present the excitation/emission strategy, experimental setup, and results of an implementation of krypton tagging velocimetry (KTV). KTV is performed as follows: (i) seed a base flow with krypton; (ii) photosynthesize metastable krypton atoms with a frequency-doubled dye laser to form the tagged tracer; (iii) record the translation of the tagged metastable krypton by imaging th...

Review of fluid flow and convective heat transfer within rotating disk cavities with impinging jet

Fluid flow and convective heat transfer in rotor-stator configurations, which are of great importance in different engineering applications, are treated in details in this review. The review focuses on convective heat transfer in predominantly outward air flow in the rotor-stator geometries with and without impinging jets and incorporates two main parts, namely, experimental/theoretical methodo...

Hydrodynamic Characteristics of Staggered Ribbed Backward Facing Step Flow with Inclined Impinging Jet

In this paper, A numerical study has been conducted to predict the hydrodynamic characteristics of the staggered ribbed backward facing step flow with inclined impinging jet. The impinging jet flow was inclined towards the main cross flow and the angle of inclination is ranged from  30 to  90 . The ribs were in staggered arrangement and aligned after the slot jet in normal direction to the ma...
