Impinging jets are characterized by an acoustic feedback resonance capable of generating intense tones. This investigation examines changes in single impinging jet (SIJ) dynamics when another is added alongside to form a dual (DIJ) arrangement interest vertical takeoff and landing applications. The emphasis on the hydrodynamic coupling region between jets, which affects aircraft surface loading...
In this paper, construction of triplet atmospheric plasma jet using argon, air, oxygen and nitrogen gases is reported. Bactericidal effect of the plasma jet is also investigated. To that end, longitudinal geometric configuration for the electrodes was chosen because it would increase the jet length. Electrical characteristics, jet length dependencies on the applied voltage and gas flow rate wer...
The performance of a corner based impinging jet ventilation system (CIJV) in an office environment was evaluated numerically. evaluation done both terms the local thermal comfort and indoor air quality. Three different inlet configurations were tested for range outdoor temperatures that included winter summer conditions. In quality, results showed CIJV performed better than traditional mixing s...
Newtonian impinging jets have been investigated for decades. However, limited is known about non-Newtonian impinging jets. The present work attempts to improve this situation by performing high-fidelity numerical simulations of non-Newtonian impinging jet dynamics. Emphasis is placed on the near field of the liquid sheet formed by the impingement of two shear-thinning (viscosity deceases with i...
many experimental studies have been conducted on development of the scour hole as a result of vertical jet impaction. research has shown that aeration of the nappe flow in the model is much weaker than that in the prototype. therefore, the influence of aeration on scour holes needs further study. experimental investigation of the effects of air entrainment and tail water depth on the scour hole...
Radiant floor heating systems provide comfortable indoor thermal environment. Primary air supply can be used to remove contaminants in the space heated by radiant floor. In this study, performance of integrated system impinging jet ventilation (IJV) and was numerically investigated. The lowest capacity 0 W/m 2 gradually increased 50W/m , primary temperature supplied IJV were 14, 16 18°C, respec...
