The creation of open porous structures with an extremely high surface area is of great technological relevance. The electrochemical deposition of metal foams around co‐generated hydrogen bubbles that act as templates for the deposition is a promising, cheap and simple approach to the fabrication of new electrocatalyst materials. Metal foams obtained by dynamic hydrogen bubble templating (DHBT) offer an intrinsically high electrical conductance with an open porous structure that enables the fast transport of gases and liquids. As an additional benefit, the confined space within the pores of DHBT metal foams may act as small reactors that can harbour reactions not possible at an open electrode interface. The number, distribution, and size of the pores can be fine‐tuned by an appropriate choice of the electrolysis parameters so that metal foam catalysts prepared by the DHBT technique meet certain requirements. In this paper, we review the preparation of certain metal foams, and their applications as catalysts for the electrochemical reduction of CO2.

Foam materials produced by physical process are common in the field of material engineering such as foamed asphalt. Considering heat and phase transfer, the complicated nonlinear phenomenon of foaming and decay process is difficult to be described numerically. In this paper, a multicomponent thermal lattice Boltzmann model for simulation of physical foaming and decay process is proposed. The model combines a thermal single-component phase change model with a multicomponent model, and the two models are verified separately. The physical foaming and decay process is solved numerically based on the proposed model. Simulation results show the influence of the distribution and content of the phase-change component on the expansion rate and decay time during physical foaming and decay process.

“…The corrected Fritz model 6 is one of the most reliable models for prediction of the bubble diameter for the boiling of pure liquids and also liquid mixtures. Stephan 7 modified the Fritz model 6 by involving three dimensionless numbers, namely, Archimedes, Prandtl, and Jacob numbers. This model is used for boiling pure liquids and a few solutions.…”

“…Van Stralen and Zijl 8 proposed a model in an experimental study using the bubble growth mechanism, which includes the Jacob number and thermal diffusivity of the solution. Zuber 9, Cole and Rohsenow 10, and Cole 11 suggested models by changing the Fritz 6 model and taking into account the physical properties and the change in the contact angle.…”

Prediction of boiling heat transfer for pool boiling systems is crucial from the viewpoint of safe operation as well as in terms of logical use of energy. Here, five pool boiling processes for calculating the bubble detachment diameters are described. The effects of liquid density and vapor density on the bubble detachment diameter of these pool boiling systems, namely, ethanol, methanol, water, Na 2 SO 4 -water, and NaCl-water, are determined by applying response surface methodology. According to P-values and analysis of variance, there is a good agreement between the obtained regression models for the five pool boiling processes and experimental data for estimation of the bubble detachment diameters.
