Book Description
The book summarises the outcom of a priority research programme: 'Analysis, Modelling and Computation of Multiphase Flows'. The results of 24 individual research projects are presented. The main objective of the research programme was to provide a better understanding of the physical basis for multiphase gas-liquid flows as they are found in numerous chemical and biochemical reactors. The research comprises steady and unsteady multiphase flows in three frequently found reactor configurations, namely bubble columns without interiors, airlift loop reactors, and aerated stirred vessels. For this purpose new and improved measurement techniques were developed. From the resulting knowledge and data, new and refined models for describing the underlying physical processes were developed, which were used for the establishment and improvement of analytic as well as numerical methods for predicting multiphase reactors. Thereby, the development, lay-out and scale-up of such processes should be possible on a more reliable basis.

Book Description
The research concerns the experimental and theoretical studies of the flow of a predominantly liquid two-phase fluid in nozzles and diffusers, undertaken as part of a longrange program dealing with the development of a gas-driven jet pumpt for rocket engines. The physical description of the flow is based on momentum, heat, and mass transfer phenomena, droplet mechanics, and the influence of flow geometry and operating conditions. As the mass ratio of one of the components is increased, it is imperative to consider at least some aspects of the discreteness of the component of lower volume in mass and energy transfer processes in a theoretical analysis for a first-order prediction of velocities, droplet diameters, and pressure for the flow in an accelerating or nozzle flow and a decelerating or diffuser flow. In the nozzle experiments, the total flow rate and the mass ratio of liquid to gas were varied to establish a series of design and performance parameters. The experimental investigation for diffusing flows was performed employing a conical diffuser and a predominantly liquid medium with the gas in the form of small bubbles dispersed in the liquid. The objects of the research were to determine the feasibility of diffusing a free jet to liquid and the effect of gas entrained in the flowing liquid. (Author).
