The Pd/H system: Transport processes and development of thermal instabilities
نویسندگان
چکیده
Recent years have witnessed renewed interest in the hydrogen economy, with emphasis n the metal/hydrogen system and its application to energy conversion efforts. Two ndustrially important aspects are emphasized, viz. the amount of hydrogen stored and the ate at which it can be transferred (absorbed/desorbed) because they are crucial factors in he design and construction of electrochemical energy conversion devices. The March 989 announcement of excess enthalpy generation [1], the Fleischmann-Pons effect, rovided an added incentive to examine in greater detail the behavior of the Pd/D system t very high electrode loadings and at high cell currents.

Role of Interatomic Potentials in Simulation of Thermal Transport in Carbon Nanotubes
Interatomic potentials, which describe interactions between elements of nanosystems, are crucial in theoretical study of their physical properties. We focus on two well known empirical potentials, i.e. Tersoff's and Brenner's potentials, and compare their performance in calculation of thermal transport in carbon nanotubes. In this way, we study the temperature and diameter dependence of thermal...
متن کاملPD Controller Design with H¥ Performance for Linear Systems with Input Delay
This paper presents H∞ control problem for input-delayed systems. A neutral system approach is considered to the design of PD controller for input delay systems in presence of uncertain time-invariant delay. Using this approach, the resulting closed-loop system turns into a specific time-delay system of neutral type. The significant specification of this neutral system is that its delayed coeff...

متن کاملCoupling Geomechanics and Transport in Naturally Fractured Reservoirs
Large amounts of hydrocarbon reserves are trapped in naturally fractured reservoirs which arechallenging in terms of accurate recovery prediction because of their joint fabric complexity andlithological heterogeneity. Canada, for example, has over 400 billion barrels of crude oil in fracturedcarbonates in Alberta, most of this being bitumen of viscosity greater than 106 cP in the GrosmontFormat...
متن کاملThe Quantum Statistical Mechanical Theory of Transport Processes
A new derivation of the quantum Boltzmann transport equation for the Fermion system from the quantum time evolution equation for the wigner distribution function is presented. The method exhibits the origin of the time - irreversibility of the Boltzmann equation. In the present work, the spin dependent and indistinguishibility of particles are also considered.
