  • Heat transfer by natural convection and radiation in three dimensional differentially heated tall cavities

    Article by P. Hernández-Castillo, J. A. Castillo, G. Huelsz in the Case Studies in Thermal Engineering (2022), 40, 102529. •Natural convection coupled to radiation in tall cavities varying the emissivity •3D CFD simulations with RANS and surface to surface models validated with experiments •The radiative heat transfer represents more than 63% of the total for hollow block cavities •Convective Nu number depends on the temperature difference for low Ra numbers
  • Evaluation of different window heights and facade porosities in naturally cross-ventilated buildings: CFD validation

    Article by S.F.Díaz-Calderón, J. A. Castillo, G. Huelsz in the Journal of Wind Engineering and Industrial Aerodynamics (2023) 232,105263. •Natural cross-ventilation by different window heights and facade porosities. •Simultaneous validation with indoor airflow distribution and pressure coefficients. •3D steady RANS CFD simulations using a single model and grid for all configurations. •Porosity increase does not imply a systematic increase of velocity homogeneity. •Bottom and middle windows with the highest porosity have the best performance.

Short-bio

Dr. J. Antonio Castillo T. is an Engineer and Architect holding the Doctor degree in Engineering in Energy.  He did two postdoctoral stays: 1) at the Laboratory of Sustainable Buildings of the Faculty of Architecture of the National Autonomous University of Mexico (UNAM) and 2) at the Institute of Renewable Energies (IER) of the UNAM. He is collaborator of the Group of Energy in Buildings of the IER-UNAM. He is also Visiting Professor in the Postgraduate and Research Section (SEPI) of the Superior School of Architecture and Engineering (ESIA) of the Politechnique National Institute (IPN). He has awarded by the Fluid Dynamic Division of the Mexican Society of Physics, by the 10th Student congress of the Center of Energy Research and by the National Congress of Students of Renewable Energies 2014. He is member of the Researcher National System – CONACYT with level 1 in the period January 2020 – December 2023. His main areas of expertise are the Bioclimatic Design and Building Wind Engineering. His research focuses on theorical, experimental and numerical modelling of natural ventilation, hygrothermal comfort, air quality, heat and mass transfer.
