In the present work, enhancement of thermal performance a central processor unit (CPU) cooling system through heat sink subjected to an impinging air jet is realized. The height duct, mode flow on sink, blowing and as well suction blow "pull" duct geometry are three important influence parameters phenomenon. results obtained show that H = 20mm, convergent 40mm in hair dryer tip provide further ...

Abstract The fluid mechanics of deposition of micron liquid (olive oil) droplets on a glass wall in an impinging tu...

BACKGROUND In clinical color Doppler examinations, mitral regurgitant jets are often observed to impinge on the left atrial wall immediately beyond the mitral valve. In accordance with fluid dynamics theory, we hypothesized that a jet impinging on a wall would lose momentum more rapidly, undergo spatial distortion, and thus have a different observed jet area from that of a free jet with an iden...

To study the influence of impinging height H/D on flow field characteristics oblique submerged jets, numerical calculation an jet was carried out based Wray–Agarwal (W–A) turbulence model. The structure and pressure distribution under various heights (1 ≤ 8) when angle θ = 45° were analyzed. results show that with increase in height, diffusion degree gradually increased velocity decreased reach...

In this paper, we investigate steady two-dimensional free-surface flows of an inviscid and incompressible fluid emerging from a nozzle, falling under gravity impinging onto horizontal wall. More precisely, for any given atmosphere pressure $$p_{atm}$$ appropriate incoming total flux Q, establish the existence jet with gravity. The two free surfaces initiate smoothly at endpoints nozzle become t...
