The growth and buoyancy induced departure of vapour bubbles at a horizontal superheated wall has been studied by global numerical methods. Integral forms of the heat transport equation have been solved by use of series expansions, obtained by the the

The electric resistance of the bubble containing electrolyte around a small circular electrode was measured as a function of current density, electrode diameter, pressure, temperature and KOH concentration, during both hydrogen and oxygen evolution.

The implosion of a translating, originally spherical, free vapour bubble due to a pressure step is described by numerical solution of the basic equations. The treatment is based on the application of a combination of the mathematical methods of collo

A theoretical description is given of a new model for mass transfer at gas-evolving electrodes where bubbles coalesce frequently. To check this model both the thickness of Nernst diffusion layer and the bubble behaviour were determined for an oxygen-

Initially, a growing vapour bubble is blown up due to an excess pressure. Continued bubble growth is governed by heat and mass diffusion. The combination of both mechanisms during the transition period may result in the occurrence of oscillations in

The growth of rotationally symmetric vapour bubbles on a horizontal plane has been studied by solving the equations of motion numerically. For this purpose, the global collocation method has been applied, cf. Zijl [1]. In this way deviations from the

The growth rate of vapour bubbles has been investigated experimentally up to departure in water boiling at pressures varying from 26·7 to 2·0 kPa (the corresponding Jakob number increasing from 108 to 2689). Comparison of the data with existing the

Pohlhausen's equation has been used to determine the initial thickness of the evaporating microlayer beneath a hemispherical vapour bubble on a superheated horizontal wall. Microlayer thickness is proportional to the square root of the distance to th

Nucleate boiling at a liquid-liquid interface was investigated experimentally and theoretically. This concept of liquid-liquid boiling is based on the introduction of a heavier thin liquid layer with higher boiling temperature between the heating sur

A survey is given of theoretical asymptotic bubble behaviour which is governed by heat or/and mass diffusion towards the bubble boundary. A model has been developed to describe the effect of turbulent forced flow on both bubble behaviour and ohmic re
