Have you registered yet? Few spots left! Computational Fluid Dynamics & Biomedical Science

Wednesday, 21 Oct 2015

Technological advances in scanning technology allow high-resolution scanning and modelling of patients. The resulting models can be used to carry out patient-specific simulations and provide more tailored diagnosis and treatment. This presentation will be focusing on the use of supercomputers to model respiratory airflows and airway-related pathology.

The Pawsey Supercomputing Centre invites you attend a seminar on applications of Computational Fluid Dynamics (CFD) in the Biomedical Sciences by Dr. Julien Cisonni and Prof. Ben Mullins.

Sleep apnea and snoring by Dr Julien Cisonni – Curtin University 

Aiming to understand the causes of sleep apnoea and snoring, and assess the treatment options supercomputing resources have been used to perform 3D computer simulations of the human upper airway. While snoring refers to the vibration of the soft tissues of the upper airway, sleep apnoea refers to how the airway closes off when the person stops breathing. By looking at the oscillations of the soft palate, which simply refers to the interaction between the airflow and soft tissue, it will be possible to have an understanding of who is more susceptible to suffer from snoring and which patients are more likely to respond to surgical treatment for snoring problems, which will in turn benefit both surgeons and patients.

Respiratory airflow and particle deposition by A/Prof Ben Mullins – Curtin University

Inhalation is the most important route of exposure to environmental and occupational pollutants, as well as an important means of medication delivery. Furthermore, many diseases such as asthma and cystic fibrosis are associated with localised or transient changes in airway geometry and/or airflow stagnation. For these reasons, accurate simulation of airways and aerosol deposition and transport are vitally important. All previous CFD work apart from the presenters in the field have utilised static model geometries – i.e. lungs that do not expand.
Current results of the “moving mesh” approach will be presented, as well as future outlook.

Presenter Bios:

Dr Julien Cisonni

Dr Cisonni received his PhD from Grenoble Institute of Technology in 2008 for his research on the production of acoustical signals in speech and pathologies at the Speech & Cognition Department of GIPSA-lab (France). After two years of Post Doctoral Research Fellowship in the Biomechanics Group and the Center for Advanced Medical Engineering and Informatics at Osaka University (Japan), he joined the Department of Mechanical Engineering at Curtin University (Western Australia) in 2012 to become Lecturer. His research lies at the boundaries between mechanical engineering, high-performance computing and bio-medical engineering. His main research interests cover Computational Fluid Mechanics, Fluid-Structure Interactions and Computational Aero-Acoustics in the Human upper airway, with application to speech production and sleep-related breathing disorders. He regularly collaborates with speech pathologist and phoneticians, as well as dentists and sleep clinicians, on various bio-fluid research projects, including the physical modelling of voiced and unvoiced sounds of speech, snoring and sleep apnea.

A/Prof Ben Mullins

Professor Mullins is an Associate Professor (Research) in the Health Science Faculty at Curtin University. He started his research career with a PhD in Environmental/Process engineering from Griffith University, followed by a 3-year research position at KIT in Germany, and engineering academic positions at Curtin and Griffith Universities. Through an interest in aerosol science and health, Ben found his way to his current position in the School of Public Health at Curtin, where he has an interest in improving our understanding of respiratory dynamics and aerosol deposition for both therapeutic and toxicological applications, using both CFD and experimental approaches. Ben has published more than 50 Journal papers, mainly in aerosol science ( ) and has current ARC funded projects on computational aerosol science.
