Numerical and experimental assessment of a downdraft gasifier for electric power in Amazon using açaí seed (Euterpe oleracea Mart.) as a fuel

Itai, Yuu; Santos, Robson; Branquinho, Mónica; Malico, … - In: Renewable Energy 66 (2014) C, pp. 662-669

The Amazon region is characterized by communities isolated from the grid that currently are using diesel engines to produce electricity and that have residual biomass energy potentials between 60 and 500 kW. In this scenario, gasification appears as an evident choice as far as energy generation...

A numerical investigation of heat transfer in phase change materials (PCMs) embedded in porous metals

Tian, Y.; Zhao, C.Y. - In: Energy 36 (2011) 9, pp. 5539-5546

The effects of metal foams on heat transfer enhancement in Phase Change Materials (PCMs) are investigated. The numerical investigation is based on the two-equation non-equilibrium heat transfer model, in which the coupled heat conduction and natural convection are considered at phase transition...

The controversial piston in the thermodynamic limit

Gruber, Christian; Pache, Séverine - In: Physica A: Statistical Mechanics and its Applications 314 (2002) 1, pp. 345-354

We consider the evolution of a system composed of N non-interacting point particles of mass m in a container divided into two regions by a movable adiabatic wall (adiabatic piston). In this talk we discuss the thermodynamic limit where the area A of the container, the number N of particles, and...

Thermal equilibrium polarization: a near-surface effect in dipolar-based molecular crystals

Bebie, H.; Hulliger, J. - In: Physica A: Statistical Mechanics and its Applications 278 (2000) 3, pp. 327-336

a re-orientation of dipoles. When linear chains are subjected to thermal equilibrium, the system develops polarity as … crystal growth, two adjacent macrodomains are formed which show opposite net polarity. Although a state near thermal … equilibrium was assumed for the attachment of dipoles, resulting crystals are metastable with respect to the global free energy …
