    • Dynamics of Airflow in a Short Inhalation 

      Bates, Alister J.; Doorly, Denis J.; Cetto, Raul; Calmet, Hadrien; Gambaruto, Alberto; Tolley, Neil; Houzeaux, Guillaume; Schroter, Robert (The Royal Society, 2015-01-06)
      Article
      Open Access
      During a rapid inhalation, such as a sniff, the flowin the airways accelerates and decays quickly. The consequences for flow development and convective transport of an inhaled gas were investigated in a subject geometry ...
    • Fluid-structure interaction based on HPC multicode coupling 

      Cajas García, Juan Carlos; Houzeaux, Guillaume; Vázquez, Mariano; Garcia Gasulla, Marta; Casoni Rero, Eva; Calmet, Hadrien; Artigues, Antoni; Borrell Pol, Ricard; Lehmkuhl Barba, Oriol; Pastrana Maldonado, Daniel; Yáñez, David; Pons, Ramon; Martorell Lopez, Jordi (2018)
      Article
      Restricted access - publisher's policy
      The fluid-structure interaction (FSI) problem has received great attention in the last few years, mainly because it is present in many physical systems, industrial applications, and almost every biological system. In the ...
    • Large-scale CFD and micro-particles simulations in a large human airways under sniff condition and drug delivery application 

      Calmet, Hadrien (Universitat Politècnica de Catalunya, 2020-11-10)
      Doctoral thesis
      Open Access
      As we inhale, the air drawn through our nose undergoes successive accelerations and decelerations as it is turned, split, and recombined before splitting again at the end of the trachea as it enters the bronchi. Fully ...
    • Large-scale CFD simulations of the transitional and turbulent regime for the large human airways during rapid inhalation 

      Calmet, Hadrien; Gambaruto, Alberto M.; Bates, Alister J.; Vázquez, Mariano; Houzeaux, Guillaume; Doorly, Denis J. (Elsevier, 2016-02-01)
      Article
      Open Access
      The dynamics of unsteady flow in the human large airways during a rapid inhalation were investigated using highly detailed large-scale computational fluid dynamics on a subject-specific geometry. The simulations were ...
    • Nasal sprayed particle deposition in a human nasal cavity under different inhalation conditions 

      Calmet, Hadrien; Inthavong, Kiao; Eguzkitza, Beatriz; Lehmkuhl, Oriol; Houzeaux, Guillaume (Public Library of Science, 2019-09-06)
      Article
      Open Access
      Deposition of polydisperse particles representing nasal spray application in a human nasal cavity was performed under transient breathing profiles of sniffing, constant flow, and breath hold. The LES turbulence model was ...
    • Scientific Big Data Visualization: a Coupled Tools Approach 

      Artigues, Antoni; Cucchietti, Fernando M.; Tripiana, Carlos; Vicente, David; Calmet, Hadrien; Marín, Guillermo; Houzeaux, Guillaume; Vázquez, Mariano (South Ural State University (Chelyabinsk, Russia), 2015-02)
      Article
      Open Access
      We designed and implemented a parallel visualisation system for the analysis of large scale time-dependent particle type data. The particular challenge we address is how to analyse a high performance computation style ...
    • Subject-variability effects on micron particle deposition in human nasal cavities 

      Calmet, Hadrien; Kleinstreuer, Clement; Houzeaux, Guillaume; Kolanjiyil, Arun Varghese; Lehmkuhl, Oriol; Olivares, Edgar; Vázquez, Mariano (Elsevier, 2018-01)
      Article
      Open Access
      Validated computer simulations of the airflow and particle dynamics in human nasal cavities are important for local, segmental and total deposition predictions of both inhaled toxic and therapeutic particles. Considering ...
    • The OTree: multidimensional indexing with efficient data sampling for HPC 

      Cugnasco, Cesare; Calmet, Hadrien; Santamaria Mateu, Pol; Sirvent Pardell, Raül; Eguzkitza, Ane Beatriz; Houzeaux, Guillaume; Becerra Fontal, Yolanda; Torres Viñals, Jordi; Labarta Mancho, Jesús José (Institute of Electrical and Electronics Engineers (IEEE), 2019)
