  • Experimental analysis of the influence of microcapsule mass fraction on the thermal and rheological behavior of a PCM slurry
    Applied Thermal Engineering, 2014
    Co-Authors: Monica Delgado, Ana Lázaro, Conchita Peñalosa, Bel n Zalba
    Abstract:

    Abstract A microencapsulated PCM (Phase Change Material) slurry with three different PCM mass fractions (14, 20 and 30%) has been analyzed. The present study investigates the influence of the PCM microcapsule mass fraction on the thermal and rheological characterization. Specifically, the Enthalpy–Temperature curves, the Thermal Conductivity–Temperature curves and the Viscosity–Shear rate curves have been determined. In addition, the physical stability under thermo-mechanical cycles has also been studied, as well as the Heat Transfer Phenomenon and the fluid mechanics. The results have shown an enhancement in the Heat Transfer Phenomenon, the slurry with 20% PCM microcapsules being the best option for use as a Heat Transfer fluid. Rupture of the PCM microcapsules was only observed for the slurry with 30% PCM microcapsules, after being pumped during three weeks and having experienced 10,000 solidification–melting cycles.

  • experimental analysis of a microencapsulated pcm slurry as thermal storage system and as Heat Transfer fluid in laminar flow
    Applied Thermal Engineering, 2012
    Co-Authors: Monica Delgado, Javier Mazo, Ana Lázaro, Jose M Marin, Bel n Zalba
    Abstract:

    Abstract A microencapsulated PCM (Phase Change Material) slurry is a dispersion where the PCM, microencapsulated by a polymeric capsule, is dispersed in water. Compared to water, these new fluids have a higher Heat capacity during the phase change and a possible enhancement, as a result of this phase change, in the Heat Transfer Phenomenon. From the literature review, the existing experimental results are found incomplete and contradictory in many cases. For this reason the objective of this investigation is to analyze the Heat Transfer Phenomenon in mPCM slurries, proposing a new methodology, developed by the authors. In this manner, an experimental analysis using a slurry with a 10% weight concentration of paraffin has been conducted to study it as a thermal storage material and as a Heat Transfer fluid. The results demonstrated an improvement of approximately 25% on the convective Heat Transfer coefficient when compared to water.
