Modeling of Heat Transfer in a Mist/Steam Impinging Jet
The addition of mist to a flow of steam or gas offers enhanced cooling for many applications, including cooling of gas turbine blades. The enhancement mechanisms include effects of mixing of mist with the gas phase and effects of evaporation of the droplets. An impinging mist flow is attractive for study because the impact velocity is relatively high and predictable. Water droplets, less than 1...
متن کاملMist/Steam Heat Transfer in Confined Slot Jet Impingement
Internal mist/steam blade cooling technology has been considered for the future generation of Advanced Turbine Systems (ATS). Fine water droplets of about 5 mm were carried by steam through a single slot jet onto a heated target surface in a confined channel. Experiments covered Reynolds numbers from 7500 to 25,000 and heat fluxes from 3 to 21 kW/m. The experimental results indicate that the co...
متن کاملHeat Transfer of an Impinging Jet on a Plane Surface
Abstract—A cold, thin film of liquid impinging on an isothermal hot, horizontal surface has been investigated. An approximate solution for the velocity and temperature distributions in the flow along the horizontal surface is developed, which exploits the hydrodynamic similarity solution for thin film flow. The approximate solution may provide a valuable basis for assessing flow and heat transf...
متن کاملPrediction of turbulent heat transfer in impinging jet geometries
This chapter summarizes the current knowledge on the numerical prediction of turbulent impinging jet flows. The predictive capabilities of numerical models are evaluated by careful comparison with experimental fluid flow and heat transfer data. Turbulent fluctuations in the velocity field are mathematically modelled using the Reynolds Averaged Navier–Stokes (RANS) methodology. Turbulence is ass...
متن کاملNumerical study of a confined slot impinging jet with nanofluids
BACKGROUND Heat transfer enhancement technology concerns with the aim of developing more efficient systems to satisfy the increasing demands of many applications in the fields of automotive, aerospace, electronic and process industry. A solution for obtaining efficient cooling systems is represented by the use of confined or unconfined impinging jets. Moreover, the possibility of increasing the...
