Available in PDF, EPUB and Kindle. Book excerpt: This thesis reports the results of an experimental study into the flow and heat transfers associated with both inclined and orthogonally impinging axisymmetric air jets. The majority of previously reported studies have been mainly confined to orthogonally impinging jets in stagnant surroundings. In this investigation, free jets as well as the effects of crossflows are considered. This investigation is Primarily concerned with local heat transfer variations. The experimental tests were. conducted with a single 12.7 mm diameter jet impinging on a flat surface, and heat transfers were evaluated using a heat-mass transfer analogy (t e Chilton-Colburn analogy). The sublimation of naphthalene was employed as the mass transfer technique. The flowfield associated with impinging jets has a significant influence on their heat transfer characteristics., In view of the present limited level of understanding of this 'complex' flowfield, extensive flow visualisation techniques were employed in this present investigation. Those were primarily intended to aid interpretation of the experimental heat transfer results, and also to provide further physical understanding of the flowfields resulting from the interactions between impinging jets and crossflowing streams. The flow and heat transfer tests conducted in the programme of work reported in this thesis covered typical ranges of flow parameters of interest in many practical applications of jet impingement systems. Jet inclinations of 45°, 600, and 90°, nozzle to target spacings of 2,11, and 8 nozzle diameters were studied. The Reynolds nuinbers were 30,200,32,700 and 55,100 and mass velocity ratios In the range 4.0 to 3.8 were studied. The effects of these parameters on the flow and heal transfers associated with impinging jets are reported. Comparisons were drawn between the heat transfer results and those of previously reported studies where appropriate.

Available in PDF, EPUB and Kindle. Book excerpt: An experimental test facility has been designed, constructed, and commissioned for studying the convective heat transfer of an array of 55 impingement jets. Spatial variation in time averaged Nusselt number as well as spanwise time averaged Nusselt number are presented for jet Reynolds numbers of 4,000, 8,000, 12,000, and 15,000 for jet to target standoff distances of z/D=3, 4, and 5. For each of these configurations the exit flow configuration has also been varied to include both a single exit and double exit configuration. For each jet standoff distance and exit configuration, time and overall area averaged Nusselt number is presented as a function of jet Reynolds number. Animations of measured unsteady Nusselt number are presented for selected cases. Numerical simulations have been conducted using the Fluent Computational Fluid Dynamics software package. The three dimensional, compressible, Navier Stokes equations are solved. Results for Nusselt number are presented for a grid dependency study of a steady, single impingement jet impacting a target surface at a standoff distance of z/D=3, at jet Reynolds numbers of 4,000 and 15,000. In the single jet grid dependency study flow is exhausted in all directions after impacting the target surface. Grids ranging from 1.2 million to 13.2 million grid points are evaluated. Unsteady simulations were conducted of a single impingement jet at a jet Reynolds number of 4000, a jet to target standoff distance of z/D=3, flow exiting in two directions, and a pair of repeating boundaries in the other two directions. Two cases were studied. The first with a spacing between the two repeating boundaries of y/D=6 and the second with a spacing of y/D=3. For both cases, contour plots of time averaged, as well as animations of unsteady in plane velocity magnitude, normal component of vorticity, and Nusselt number are presented. Unsteady simulations were also conducted of eleven impingement jets at a jet Reynolds number of 4,000, a jet to target standoff distance of z/D=3, and a double exit configuration. Two cases were studied. The first with a spacing between the two repeating boundaries of y/D=4.03 and the second with a spacing of y/D=3. For both cases, contour plots of time averaged in plane velocity magnitude, normal component of vorticity, pressure, temperature, and Nusselt number are presented. Animations of contours of in plane velocity magnitude, normal component of vorticity, and Nusselt number are also presented. Spanwise time average Nusselt number for both eleven jet numerical cases is compared to that of the central row of an experimental case with a double exit configuration. Comparisons are also made between spanwise average Nusselt number for the central jet of an experimental case, a single jet numerical, the single jet numerical cases with the repeating boundaries, as well as the central jet of the eleven jet numerical cases.
