Multiplex process diaphragm pump meets industry demands for flexibility
82
ANNUAL LITERATURE SURVEY 1996
modern single stage'or multistage barrel pump so there is not much new in centrifugal pumping. The Sweepax approach tackles a very specific pro blem in a very specific market with an original solution. It consists of three stages in series: a centripetal stage, an axial inducer and a centrifugal stage. This is to pump slurries and waste products with such high concentrations of solids in suspension that they do not flow naturally into the pump.
Multiplex process diaphragm pump meets industry demands for flexibility World Pumps, 1996, 362/- (30-32). In English. Traditionally, demanding and hazardous processing operations have involved the use of fixed stroke positive displacement reciprocating pumps, such as the triplex type as well as multi-stage and high speed centrifugal pumps. However, these contain inherent limitations particularly in respect of sealing and high operation costs. Leak-free and energy efficient high volume pumping of aggressive and dangerous liquids, slurries and suspensions can now be achieved by using a new concept of process pump, the 'Novaplex' developed by Bran + Luebbe.
Waves and nonlinear processes in hydrodynamics Grue J., Gjevik B. & Weber J.E., (Kluwer; Fluid Mechanics and its Applications, 34), ISBN (HARDBACK) 0 7923 40, 1996. In English. Waves and Nonlinear Processes in Hydrodynamics contains thirty-one papers by international experts in hydrodynamics based on talks at a symposium held in honour of Professor Enok Palm on his 70th birthday. The volume begins with two review papers on the history of hydrodynamic research at the University of Oslo and on engineering applications of hydrodynamics in the offshore industry. It continues with recent developments in marine hydrodynamics, nonlinear wave-diffraction, wave drift damping, nonlinear wave theory, breaking of waves, effect of surface tension on wave motion, nonlinear stability, thermal convection, turbulence stratified flows, particle drift and dispersion, self-organization, damping of waves in kelp forests and ocean modelling.

In English. The selection of refereed papers included in this book are primarily concerned with ongoing work and the latest advances in heat transfer. These transactions address the key areas of: radiation and combustion; convection; conduction; two-phase flow and condensation; boiling; numerical techniques and modelling; heat exchangers and heat transfer augmentation; and applied heat transfer and measurement.

Annual review of fluid mechanics. Volume 28 Lumley J.L., Van Dyke M. & Reed H.L., (Annual Reviews Inc, Palo Alto), ISBN (HARDBACK) O 8243 07, 1996. In English. This volume begins with a review of the Vtb Volta Congress and continues by including thirteen papers entitled as follows: numerical models for two-phase turbulent flows; new trends in large-eddy simulations of turbulence; vorticity, free surface, and surfactants; fully elastic instabilities of multiphase flow in porous media; modelling of the oceanic general circulation; computations of nonlinear free-surface flows; the role of surfacewave breaking in air-sea interaction; fluid phenomena in scramjet combustion systems; the fluid dynamics of parachute inflation; linear instability theory applied to boundary layers; atmospheric lee waves; vortex dynamics in the cylinder wake.

Axisymmetric thermophoresis of multiple aerosol spheres Shih Chen H. & Huan Keh J., Aerosol Science & Technology, 1996, 24/1 (21-35). In English. A semianalytieal study of the thermophoretic motion of a finite chain of aerosol spheres along the line through their centers is presented. The spheres may differ in radius, thermally conductivity, and in surface properties, and they are allowed to be unequally spaced. Also, the spheres can be either freely suspended in the gaseous medium or connected by infinitesimally thin rods. The Knudsen numbers are assumed to be small so that the fluid flow is described by a continuum model with a thermal creep and a hydrodynamic slip at the particle surfaces. Through the use of a boundary-collocation method, a set of energy and momentum equations governing this problem is solved in the quasisteady limit and the interaction effects are computed for various cases. For the thermophoretic motion of two-sphere systems, the numerical results for the particle velocities agree very well with the exact calculations using spherical bipolar coordinates. For the cases of two or three spheres touching one another, the numerical solutions for the particle interaction parameters compare quite favorably with the formulas derived analytically.
