Flow And Heat Transfer Characteristics Of Turbulent Swirling Impinging Jets [Thesis], Muhammad Ikhlaq
Flow And Heat Transfer Characteristics Of Turbulent Swirling Impinging Jets [Thesis], Muhammad Ikhlaq
Theses: Doctorates and Masters
Numerous industrial applications rely on impinging jets to impart convective heat and mass transfer in processes ranging from the cooling of electronic devices and gas turbine blades to drying of paper and food products. Conventionally, non-swirling impinging jets have been employed, but some studies have shown that inducing swirl allows better control of uniformity and improved convective fluxes. A better understanding of the underlying physical mechanisms that lead to such behaviour warrants deeper insights into the flow and heat transfer characteristics of impinging jets, both swirling and non-swirling. Whilst important to achieve, the flow field of an impinging jet is …

An Experimental And Numerical Study Of Surface Interactions In Turbulent Swirling Jets, Zahir Uddin Ahmed
Theses: Doctorates and Masters
Convective heat transfer and drying processes are found in industrial applications from gas turbine blade cooling to drying of food products and paper. In many instances, these processes rely on either a single or an array of fluid jets which impinge onto a surface. Traditionally, non-swirling impinging jets have been used, but interest surrounds possible advantages from imposing swirl into these jets to further promote heat and mass transfer at the surface. The challenge of resolving this question is that including swirl further complicates fluid-surface interactions. Studies are faced with the complexity of flow behaviour, the need for intricate measurement …
