Non - flow , and what flow to subtract in jet - correlation

چکیده
We derive an analytical form for jet-correlation flow-background in a cluster approach. We argue that the elliptic flow parameter to be used in jetcorrelation background is that from two-particle method excluding non-flow correlation irrelevant to reaction plane, but including cross-terms between cluster correlation and cluster flow. We verify our result with Monte Carlo simulations. We discuss implications of our result on Mach-cone signal and jet modification in general.

Experimental study and numerical simulation of three dimensional two phase impinging jet flow using anisotropic turbulence model
Hydrodynamic of a turbulent impinging jet on a flat plate has been studied experimentally and numerically. Experiments were conducted for the Reynolds number range of 72000 to 102000 and a fixed jet-to-plate dimensionless distance of H/d=3.5. Based on the experimental setup, a multi-phase numerical model was simulated to predict flow properties of impinging jets using two turbulent models. Mesh...

The study of interactions of jet into cross flow at different longitudinal and transverse angles of jet was studied. The following components were designed and constructed: a low velocity wind tunnel to produce the uniform flow, a flat plate with a traverse injection system to simulate the jet injection, and a spatial rake to measure the total pressure. The tests were carried out at longitudina...

متن کاملThermal Performance of Jet Impingement with Spent Flow Management
The present study proposes novel micro-jet impingement heat sink with effusion holes for flow extraction. The design consists of impingement nozzles surrounded by multiple effusion holes to take away the spent fluid. A three-dimensional numerical model is used for steady, incompressible, laminar flow and conjugate heat transfer for the performance analysis of the proposed design. The computatio...
متن کاملUnsteady Numerical Investigations of Flow and Heat Transfer Characteristics of Nanofluids in a Confined Jet Using Two-Phase Mixture Model
The development of high-performance thermal systems has increased interest in heat transfer enhancement techniques. The application of additives to heat transfer liquids is one of the noticeable effort to enhance heat transfer. In this paper two-dimensional unsteady incompressible nanofluid flow in a confined jet at the laminar flow regime is numerically investigated. The Mixture model is consi...
