Numerical investigations of heat transfer and pressure drop characteristics in multiple jet impingement system
TL;DR: In this paper, the physics of impinging jets in large array in low Reynolds number regime was discussed and the major pressure loss in the system is due to contraction effect at the nozzle entrance and due to viscous losses.

A dynamic subgrid‐scale eddy viscosity model
TL;DR: In this article, a new eddy viscosity model is presented which alleviates many of the drawbacks of the existing subgrid-scale stress models, such as the inability to represent correctly with a single universal constant different turbulent fields in rotating or sheared flows, near solid walls, or in transitional regimes.

Eddies Stream, and Convergence Zones in Turbulent Flows
TL;DR: In this article, a set of objective criteria were found which describe regions in which the streamlines circulate, converge, or diverge, and form high streams of high velocity flow.
