Exploration of a horizontal confined impinging heated jet using both experimental and numerical methods

Abstract

Impinging jets have been fascinating experimentalists and numerical modellers for many years with seemingly simple geometries revealing complex flow characteristics. Due to their high heat and mass transfer rates, impinging jets find wide use in engineering and industrial applications. Not only is the impinging jet interesting in isolation but it is often found as part of a more complex flow situation within an industrial setting. The dilemma for analysts under commercial pressure is always what level of detail is required for the results to be helpful but available in a reasonable time. The aims of this paper are: To understand a horizontal confined heated impinging jet using a combination of visualisation, experimental and numerical techniques. To understand the significance numerical modelling decisions can have in the context of an industrial setting. To make informed decisions about turbulence modelling dependent on the context of the flow problem
