This paper presents an original approach to the numerical modelling of unilateral contact by the finite element method. The main point is the development of mixed contact finite elements in which the displacement field and the contact stress field (pressure and friction shear) are discretized independently. The theory, based on variational principles, is first presented in the framework of infinitesimal deformations and, subsequently, is extended to large inelastic strains. [less ▲]

Until now, the choice of a heating system is, in most cases, rather intuitive, but not based on significant comparisons among the many options available on the market. Friendly calculation tools are badly needed. A prototype of simulation model is shortly presented in this paper. It is designed as a preliminary design tool, allowing the different partners of a project to evaluate the energy impact of the very first design options: building envelope heat transfer coefficients, glazing areas, orientations, solar factors, ventilation mode, heat emission, distribution, generation and control strategy. The heating demand is calculated hour by hour with consideration to the time variations of inside and outside temperatures and free gains, to the control law and to the heating power actually available. The emitter is a water-ambient heat exchanger. It may have some thermal mass. Two emitters are here proposed: the radiator and the flow heating system. A steady state water distribution model is included in this simulation; it takes heat losses in unheated spaces into account: Three typical heating sources are proposed: classical boiler, condensing boiler and heat pump. All heat generators are here simulated with the help of very simple polynomial (“daughter”) models. The polynomial expressions are fitted on the simulation results obtained with reference (“mother”) models, themselves fitted on experimental data available. Examples of simulation results are presented in the paper. [less ▲]

We show that a double emulsion (oil in water in oil) can be created starting from a compound droplet (surfactant solution in oil). The compound drop bounces on a vertically vibrated liquid surface. When the amplitude of the vibration exceeds a threshold value, the oil layer penetrates the water content and leaves a tiny oil droplet within. As this phenomenon occurs at each vigorous impact, the compound drop progressively transforms into a double emulsion. The emulsification threshold, which is observed to depend on the forcing frequency but not on the drop size, is rationalized by investigating the impact of compound drops onto a static liquid surface. The droplet creation occurs when the kinetic energy released at impact is larger than the energy required to deform the compound drop, namely when the Weber number is higher than a given threshold value.
