Book excerpt: The mixing of liquids, solids and gases is one of the most commonunit operations in the food industry. Mixing increases thehomogeneity of a system by reducing non-uniformity or gradients incomposition, properties or temperature. Secondary objectives ofmixing include control of rates of heat and mass transfer,reactions and structural changes. In food processing applications,additional mixing challenges include sanitary design, complexrheology, desire for continuous processing and the effects ofmixing on final product texture and sensory profiles. Mixing ensures delivery of a product with constant properties. Forexample, consumers expect all containers of soups, breakfastcereals, fruit mixes, etc to contain the same amount of eachingredient. If mixing fails to achieve the requiredproduct yield, quality, organoleptic or functional attributes,production costs may increase significantly. This volume brings together essential information on theprinciples and applications of mixing within food processing. Whilethere are a number of creditable references covering generalmixing, such publications tend to be aimed at the chemical industryand so topics specific to food applications are often neglected.Chapters address the underlying principles of mixing, equipmentdesign, novel monitoring techniques and the numerical techniquesavailable to advance the scientific understanding of food mixing.Food mixing applications are described in detail. The book will be useful for engineers and scientists who need tospecify and select mixing equipment for specific processingapplications and will assist with the identification and solving ofthe wide range of mixing problems that occur in the food,pharmaceutical and bioprocessing industries. It will also be ofinterest to those who teach, study and research food science andfood engineering.

Abstract: Abstract of the thesis entitled "Mixing of Turbulent Advected Line Puffs" submitted by CHU Chi Keung Paul for the degree of Doctor of Philosophy at the University of Hong Kong in June 1996.i Abstract Wastewater after land-based treatment is often discharged in the form of buoyant jet into a river or tidal flow via a sewage outfall. The initial dilution achieved by the outfall is of great importance to the effectiveness of such a disposal scheme. Limited by inadequate experimental techniques, detailed information on the scalar and flow field of the two important asymptotic regimes of a buoyant jet in crossflow, the momentum-dominated far field (MDFF) and buoyancy-dominated far field (BDFF), are scarce in previous studies. In particular, the dilution prediction and our physical understanding of the vortex-pair flow in the MDFF need much improvement. The methodology of advected line puffs (ALP) and thermals (ALT), which overcomes some major difficulties in performing experiment in the MDFF and BDFF, is adopted in the present investigation to study the mixing of a turbulent buoyant jet in crossflow. Digital image processing techniques are applied to quantify the visual properties of ALP/ALT from the flow visualization (side view). The results strongly support the feasi- bility of the present methodology. The numerical coefficients of the self-similar solutions in MDFF/BDFF are obtained. Contrary to previous studies, the spreading rates of ALP and ALT are found to be quite similar. The cross-sectional instantaneous and time-averaged scalar field of ALP are measured using non-intrusive laser-induced fluorescence techniques; the cross-sectional flow field is de- termined using laser doppler anemometry. Detailed information about the turbulence structure in the developed stage including instantaneous maximum concentration, turbulent intensity and maximum vertical velocity are obtained. The flow is highly intermittent with coherent rotating turbulent patches that randomly move around the entire section. The intermittency is generally less than 1; ambient fluid can be present anywhere in the cross-section. The time-averaged measurements show clearly the kidney-shaped (often bifurcated) scalar field and the vortex-pair flow. A similar study of jet in coflow is also performed. Using the top-hat average velocity as the characteristic velocity in a spreading hypothesis, an integral model is formulated and the predictions show good agreement with the experiments. The correlation of conceptual model parameters with physical entities is established. It is found that the edge defined by the top-hat profile is a proper representation of jet boundary in both the near and far field. The significant loss of ALP impulse, as predicted by a 2D line puff turbulence model, which implies the existence of added mass in the MDFF, is experimentally confirmed. Solely based on the experimentally determined spreading rate, and added mass coefficient, an integral model can be developed. The predictions compare favorably with the present andii previous experimental results. Flow visualization of the major vortical features of a jet in crossflow are studied in relation to the mixing. Although the wake vortices have little effect on the scalar field, contrary to previous studies, it is observed that their origin is not necessarily related to the wall boundary layer but is closely related to the vortex shedding in

Available in PDF, EPUB and Kindle. Book excerpt: It has been demonstrated that the conventional technique of fixed-laser-sheet flow visualization can be extended to include three-dimensional visualization by means of a scanning laser sheet. This system was implemented using a rotating mirror in conjunction with appropriate fixed optics. A space-filling three-dimensional data base was digitally obtained from the imaging and recording units, and was processed to yield a variety of three dimensional views of the flow field in addition to obtaining quantitative results regarding mixing levels and velocities. Laser-sheet scanning was first applied in a study of boundary-layer turbulence in which active control was implemented. The flow visualization readily indicated the near-wall instabilities present in turbulent spots and synthetic turbulent boundary-layers. When control was attempted using an array of surface heating elements, the visualization technique graphically illustrated the attenuation of the near-wall sublayer 'streaks' and resultant quiescent outer flow.

Book excerpt: This is the 2nd edition of the book, Flow Visualization: Techniques and Examples, which was published by Imperial College Press in 2000. Many of the chapters have been revised and updated to take into consideration recent changes in a number of flow visualization and measurement techniques, including an updated high quality flow gallery. Unique among similar publications, this book focuses on the practical rather than theoretical aspects. Obtaining high quality flow visualization results is, in many ways, more of an art than a science, and experience plays a key deciding role. The depth and breadth of the material will make this book invaluable to readers of all levels of experience in the field.
