Force measurements with the atomic force microscope: Technique, interpretation and applications

to be done in this area. Face recognition is a problem that scarcely clamoured for attention before the computer age but, having surfaced, has involved a wide range of techniques and has attracted the attention of some fine minds (David Mumford was a Fields Medallist in 1974). This singular application of mathematical modelling to a messy applied problem of obvious utility and importance but with no unique solution is a pretty one to share with students: perhaps, returning to the source of our opening quotation, we may invert Duncan's earlier observation, 'There is an art to find the mind's construction in the face!'.

Linear and nonlinear waves, by G. B. Whitham. Pp.636. £50. 1999. ISBN 0 471 35942 4 (Wiley).

This book describes and explains the fundamental physical processes involved in bubble dynamics and the phenomenon of cavitation. It is intended as a combination of a reference book for those scientists and engineers who work with cavitation or bubble dynamics and as a monograph for advanced students interested in some of the basic problems associated with this category of multiphase flows. A basic knowledge of fluid flow and heat transfer is assumed but otherwise the analytical methods presented are developed from basic principles.

The book begins with a chapter on nucleation and describes both the theory and observations of nucleation in flowing and non-flowing systems. The following three chapters provide a systematic treatment of the dynamics of the growth, collapse or oscillation of individual bubbles in otherwise quiescent liquids. Chapter 4 summarizes the state of knowledge of the motion of bubbles in liquids. Chapter 5 describes some of the phenomena which occur in homogeneous bubbly flows with particular emphasis on cloud cavitation and this is followed by a chapter summarizing some of the experiemntal observations of cavitating flows. The last chapter provides a review of the free streamline methods used to treat separated cavity flows with large attached cavities.

Cavitation and Bubble Dynamics

The boundary layer equations for plane, incompressible, and steady flow are 

$$\matrix{ {u{{\partial u} \over {\partial x}} + v{{\partial u} \over {\partial y}} = - {1 \over \varrho }{{\partial p} \over {\partial x}} + v{{{\partial ^2}u} \over {\partial {y^2}}},} \cr {0 = {{\partial p} \over {\partial y}},} \cr {{{\partial u} \over {\partial x}} + {{\partial v} \over {\partial y}} = 0.} \cr }$$

Boundary Layer Theory

A method and apparatus utilizing inelastic neutron scattering for measuring the volume fractions of the various constituents of a multiconstituent substance. A source of fast neutrons is positioned proximate the substance. A detection system is provided to monitor the gamma emissions resulting from inelastic scattering of the fast neutrons from the various nuclides within the substance. The resulting measurement of the relative abundance of gamma emissions characteristic of the various nuclides within the substance is used to determine the relative concentrations of the major constituents of the substance. In a preferred embodiment, the present invention is used to provide a real-time measurement of the volume fractions of oil, gas and water in the production flowstream from an oil well.

Modelling of Dispersion of Two-Phase Releases: Part 1—Conservation Equations and Closure Relationships

Mass transfer rates in vertical gas-liquid flow were measured by an electrochemical technique. The flow regimes studied were slug, churn and annular. Average mass transfer coefficients in gas-liquid flow could be correlated by expressions similar to those for single phase flow. Fluctuations in local mass transfer coefficient could be used to indicate flow regimes. Average wall shear stress determined from the average mass transfer coefficients agreed with values calculated from measurements of pressure drop, void fraction and flow rate, provided flow reversals did not occur. The results indicate that the electrochemical technique could be used to measure wall shear stress in accelerating gas-liquid flows, such as critical flow.



On a mesure, par une methode electrochimique, les vitesses de transfert de matiere dans un ecoulement vertical gaz-liquide. Les regimes d'ecoulement etudies ont ete les suivants: annulaire, lent et bouillonnant. Qn a etabli des correlations, dans le cas des coefficients de transfert de matiere moyen dans un ecoulement gaz-liquide, en employant des expressions semblables a celles utiliees pour les ecoulements monophasiques. On a pu utiliser les fluctuations dans le coefficient de transfert de matiere local pour indiquer les regimes d'ecoulement. La contrainte de cisaillement moyenne a la paroi, determinee a partir des coefficients de transfert de matiere moyens, est en accord avec les valeurs calculees a partir de la perte de charge, de la fraction de vide et du debit, a condition qu'il n'y ait pas de reflux. Les resultats indiquent qu'on pourrait employer la methode electrochimique pour mesurer l'effort de cisaillement sur les parois dans des ecoulements gaz-liqnide ncceleres, tels que l'ecoulement critique.
