Heat 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 کاملUnsteady Turbulence Characteristics in an Undular Bore
When a river mouth has a flat converging shape with a tidal range exceeding 6 to 9 m, the river may experience a tidal bore. A tidal bore is a positive surge, and the aim of the study is to detail the turbulent field beneath an undular bore. New unsteady experiments were conducted in a large channel. Turbulence measurements were performed with high-temporal resolution using side-looking acousti...
متن کاملHydrodynamic Characteristics of Staggered Ribbed Backward Facing Step Flow with Inclined Impinging Jet
In this paper, A numerical study has been conducted to predict the hydrodynamic characteristics of the staggered ribbed backward facing step flow with inclined impinging jet. The impinging jet flow was inclined towards the main cross flow and the angle of inclination is ranged from 30 to 90 . The ribs were in staggered arrangement and aligned after the slot jet in normal direction to the ma...
متن کاملUnsteady Numerical Investigations of Flow and Heat Transfer Characteristics of Nanofluids in a Confined Jet Using Two-Phase Mixture Model
The development of high-performance thermal systems has increased interest in heat transfer enhancement techniques. The application of additives to heat transfer liquids is one of the noticeable effort to enhance heat transfer. In this paper two-dimensional unsteady incompressible nanofluid flow in a confined jet at the laminar flow regime is numerically investigated. The Mixture model is consi...
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...
