... Impinging jet pulsating jet forcing frequency Large Eddy Simulation This study is devoted to a forced turbulent plane jet emerging from a slot rectangular nozzle impinging on a semi-cylindrical surface using large eddy simulation. Both forced and unforced cases are considered...

... is projected on the hot interface between the tool and the material through a curved duct coolant distributor. The performance of such a system is strongly dependent on the fluid flow in the curved duct and on the impinging jet flow properties. To optimize cooling setup, CFD simulations and in-situ...

... 03 03 2009 Flow characteristics of turbulent impinging jets issuing, respectively, from a rectangular and a square nozzles have been investigated numerically through the solution of three-dimensional Navier-Strokes equations in steady state. Two geometries with two nozzle-to-plate...

... 03 03 2009 An experimental investigation of the impinging jet cooling from a heated flat plate has been carried out for several Reynolds numbers (Re) and nozzle to plate distances. The present results indicate that the maximum heat transfer occurs from the heated plate at stagnation...

... 08 09 2008 In this work, Large Eddy Simulation (LES) has been carried out to analyze the turbulent mixing processes in an impinging jet configuration. To characterize and quantify turbulent mixing processes, in terms of scalar structures and degree of mixing, three parameters have been...
