    1. Thermal simulation of high-power Li-ion battery with LiMn1/3Ni1/3Co1/3O2 cathode on cell and module levels (pages 564–572)

      Heat generated by change in entropy plays a significant part in the heat generation in Li-ion battery cell and should not be neglected. A DC resistance value is not enough for a proper thermal design of the battery module, and electrochemical reactions have to be taken into account.

    2. Experimental comparative study of heat pipe performance using CuO and TiO2 nanofluids (pages 573–580)

      R. Manimaran, K. Palaniradja, N. Alagumurthi and J. Hussain

      Version of Record online: 6 JUN 2013 | DOI: 10.1002/er.3058

    3. Thermal characteristics of a volumetric solar absorption system (pages 581–591)

      Osman K. Siddiqui and Bekir S. Yilbas

      Version of Record online: 13 JUN 2013 | DOI: 10.1002/er.3063

    4. Water transport into PEFC gas diffusion layer: experimental characterization of diffusion and permeation (pages 602–613)

      F. Bresciani, A. Casalegno, G. Varisco and R. Marchesi

      • the experimental methodology evaluates gas and liquid water transport through GDL quantifying effective diffusivity and breakthrough pressure
      • MPL presence causes a 5-time reduction in GDL effective diffusivity if compared with GDL without MPL
      • MPL doubles breakthrough pressure; cracks are responsible for MPL breakthrough, and permeation can occur through a wet GDL at a lower pressure if compared with a dry GDL
    5. Comparison of oil extraction methods, energy analysis and biodiesel production from flax seeds (pages 614–625)

      Mehmood Ali and Ian A. Watson

      Oil extraction yield by microwave, ultrasonic and combined assisted extraction methods with different moisture content (4%, 8% and 12%) samples showed that microwave treatment and combined treatment were not significantly different, whereas with ultrasonic treatment, the yield increased with moisture content. Oil yield and the energy requirements for flaxseed oil extraction showed that microwave treatment had the highest oil extraction energy efficiency (25.2%), followed by organic solvent (14.0%). In situ ultrasonic transesterification showed a conversion yield of 93.0% and 3.6% positive energy balance.

    6. Forecasting electricity price and demand using a hybrid approach based on wavelet transform, ARIMA and neural networks (pages 626–637)

      Sergey Voronin and Jarmo Partanen

      Version of Record online: 30 JUN 2013 | DOI: 10.1002/er.3067

      A hybrid forecast method is proposed for simultaneous prediction of electricity price and demand in the day-ahead energy market in order to capture the unique linear and nonlinear features of the price and demand series and consider interactions of both demand and price forecast processes without assuming known values for the forecast features. From the numerical studies, it is seen that the proposed method has more accurate behavior than other separate methods.

    7. Numerical investigation of combustion characteristics in an oxygen transport reactor (pages 638–651)

      A. E. Farooqui, H. M. Badr, M. A. Habib and R. Ben-Mansour

      Version of Record online: 29 JUN 2013 | DOI: 10.1002/er.3070

    8. Distribution of size in multi-evaporator air conditioning systems (pages 652–657)

      Y. Pan, S. Lorente, A. Bejan, L. Xia and S. Deng

      Version of Record online: 29 JUN 2013 | DOI: 10.1002/er.3072

      This paper reports the thermodynamic optimization of air conditioning systems with one or more evaporators, for one or more rooms. The trade-off between the power lost by fluid friction in the distribution network and the power required by the refrigerant determines the optimal allocation of hardware in the installation. The optimum diameters of the refrigerant pipelines are independent of their lengths.

    9. On the improvement of annual performance of solar thermal power plants through exergy management (pages 658–673)

      Antonio Rovira, María José Montes, Manuel Valdes, José María Martínez-Val and Fernando Varela

      • Exergy analysis of improved configurations of solar thermal power plants.
      • Double thermal energy storage keeps the HTF exergy when working at post-sunset hours.
      • Subdivision of the solar collector field reduces the temperature of the HTF in the solar field and its exergy losses.
      • Yearly energy production of both configurations is greater than that of a reference plant.
