Book Description
Heat Exchange of Tubular Surfaces in a Bubbling Boiling Bed bridges the gap surrounding the study of a boiling bed of large particles with smooth and ribbed pipes, as well as pipe bundles. The book's authors combine results from experimental studies with their varied practical experience in fields of boiling bed applications across various disciplines such as chemical, pharmacological, metallurgical and power engineering industries. This book provides readers with a deep practical understanding of how to calculate the heat engineering parameters of ribbed pipe bundles in a boiling bed, along with the hydrodynamics of the boiling bed.Researchers and experts involved in the design, development and operation of boiling bed apparatus will follow step-by-step methods and procedures to gain knowledge of the hydrodynamic and heat exchange elements of the boiling bed which can be applied to their own settings. The effect of gas velocity, size and properties of the dispersed material, the geometric characteristics of the pipe bundle is also presented, alongside data on the effect of high temperature and high pressure of gas in a dispersed system on heat exchange intensity. Covers the design of apparatus and devices with a boiling bed in various industries Includes criteria equations for calculating heat exchange, as well as data for the calculation of furnace devices Presents the structure analysis of the boiling bed with submerged pipe bundles and the calculation of the hydrodynamic resistance of the boiling bed

Book Description
"This research studied the impact of the dense vertical immersed heat exchanging tubes on the gas and solids hydrodynamic characteristics, flow regime, pressure drop, and heat transfer in a 0.14 m inside diameter gas-solid fluidized bed column of. Two sizes of vertical internal tube bundles (0.0127 and 0.0254 m) of circular arrangement have been implemented to represent the heat exchange tubes covering 25% of the column cross-sectional area. The experimental work was achieved at different operating conditions and various solids particle types that differ in average particle size, solids density, particles shape, and particles sphericity. The experimental measurements were performed using various kinds of measurement techniques such as advanced optical fiber probe for local solids and bubble hydrodynamics measurements, differential pressure transducer for pressure fluctuation measurements, advanced fast response heat transfer probe for local heat transfer coefficient measurements, probe-single ended and probe-differential pressure transducers for measuring the pressure fluctuations and pressure drop inside the bed. It was found that the immersed vertical tubes have a significant effect on the studied hydrodynamics parameters (solids velocity, solids and gas holdups, bubbles velocity, bubble frequency, and bubble chord length), flow regime, pressure drop and heat transfer coefficients inside the gas-solid fluidized bed. In which, the vertical internals improve the heat transfer performance, increase the heat transfer coefficient, reduce the pressure drop, affect the flow regimes and their transition velocities, as well as enhance the performance of the gas-solid fluidization process by improving the studied local hydrodynamic characteristics"--Abstract, page iv.
