Book Description
"The object of this thesis is to simulate the Handlos and Baron Model for mass transfer into droplets by using an iterative analog computer in order to obtain eigenvalue and other parameters in a series solution. The eigenvalues [lambda][subscript n] calculated in this work are compared with the results obtained by Wellek-Skelland using a variational technique and by Patel using numerical approaches on the digital computer. From the analytical series solution, one can calculate the fraction of solute extracted in the droplets as a function of droplet contact time. PACTOLUS, a digital-analog simulator, provides a check on the validity of analog simulation. The PACTOLUS simulation confirmed the results obtained from the analog simulation"--Abstract, leaf i.

Book Description
The field of multiphase flows has grown by leaps and bounds in the last thirty years and is now regarded as a major discipline. Engineering applications, products and processes with particles, bubbles and drops have consistently grown in number and importance. An increasing number of conferences, scientific fora and archived journals are dedicated to the dissemination of information on flow, heat and mass transfer of fluids with particles, bubbles and drops. Numerical computations and "thought experiments" have supplemented most physical experiments and a great deal of the product design and testing processes. The literature on computational fluid dynamics with particles, bubbles and drops has grown at an exponential rate, giving rise to new results, theories and better understanding of the transport processes with particles, bubbles and drops. This book captures and summarizes all these advances in a unified, succinct and pedagogical way. Contents: Fundamental Equations and Characteristics of Particles, Bubbles and Drops; Low Reynolds Number Flows; High Reynolds Number Flows; Non-Spherical Particles, Bubbles and Drops; Effects of Rotation, Shear and Boundaries; Effects of Turbulence; Electro-Kinetic, Thermo-Kinetic and Porosity Effects; Effects of Higher Concentration and Collisions; Molecular and Statistical Modeling; Numerical Methods-CFD. Key Features Summarizes the recent important results in the theory of transport processes of fluids with particles, bubbles and drops Presents the results in a unified and succinct way Contains more than 600 references where an interested reader may find details of the results Makes connections from all theories and results to physical and engineering applications Readership: Researchers, practicing engineers and physicists that deal with any aspects of Multiphase Flows. It will also be of interest to academics and researchers in the general fields of mechanical and chemical engineering.

Book Description
"This investigation was carried out to check the accuracy of the eigenvalues, [lambda][subscript n], calculated by Wellek and Skelland, using some method other than the Rayleigh-Ritz technique and also, to determine the coefficients, B[subscript n] in series solution, which were not calculated before. The eigenvalues were obtained by trial and error procedure using the standard Runge-Kutta method. The coefficients B[subscript n] were obtained by using eigenvalues. By using this information the fractional extraction was calculated as a function of droplet contact time. The Wellek-Skelland modification was also solved by finite difference technique to compute fraction extracted as a function of contact time. The eigenvalues, [lambda][subscript n], and coefficients, B[subscript n], were also obtained by Hamming's method, and the values agreed with those obtained by the Runge-Kutta method to within 2%. The first eigenvalues obtained by Wellek and Skelland and the values obtained by the author were in agreement to within 5%. The family of curves of E[subscript m] versus bt, obtained using finite difference method, is in agreement with the physical situation. Therefore, at the higher values of bt ( > 0. 5) results observed using Runge-Kutta method should be used,and at lower values of bt (
