Heat Transfer Characteristics of Swirling Impinging Jets
Impinging jets are used in a wide number of industrial cooling applications due to their high heat and mass transfer abilities. The current research is concerned with the effect of swirl on the heat transfer characteristics of jet impingement cooling. Two inserts were designed order to generate swirling flow. These two designs, “Swirl Insert A” and “Swirl Insert B”, were tested at various Reyno...
متن کاملSimulation and measurement of flow and heat transfer in two planar impinging jets
The flow and heat transfer in two planar impinging jets are investigated using Large-Eddy simulation and experiments. The jet Reynolds number based on nozzle width and centerline velocity is 500. Predictions are obtained of unforced jets in addition to forced cases in which periodic injection and suction is applied at the nozzle exit of each jet. The goal of the current effort is to characteriz...

متن کاملInvestigation of Laminar Pulsating Nanofluid Flow and Heat Transfer in a Rectangular Channel
In this study, two-dimensional pulsating unsteady flow of nanofluid through a rectangular channel with isothermal walls is investigated numerically. The set of resultant algebraic equations is solved simultaneously using SIMPLE algorithm to obtain the velocity and pressure distribution within the channel. The effects of several parameters, such as volume fraction of different nanoparticles, Rey...
متن کاملHeat Transfer under Double Turbulent Pulsating Jets Impinging on a Flat Surface
In this study, the numerical analysis of turbulent flow and heat transfer of double pulsating impinging jets on a flat surface has been investigated. The unsteady two-dimensional numerical solution for two similar and dissimilar jets was performed using the RNG k-ε model. The results showed that the RNG k-ε model has more satisfactory predictions of the Nusselt number distribution. Comparisons ...
