Computational study of flow–induced oscillation of a simplified soft palate
Khalili, Mohammadtaghi; Larsson, Martin; Müller, Bernhard (Chapter, 2017)Two-dimensional numerical simulations are employed to study fluid structure interaction of a simplified model of the soft palate in the pharynx for uniform inhalation. We take a next step towards a better biomechanical ... -
Developing an immersed boundary method for compressible flow
Kristoffersen, Frederik; Larsson, Martin; Johnsen, Sverre Gullikstad; Schröder, Wolfgang; Müller, Bernhard Theodor (Journal article; Peer reviewed, 2023)Development of a 3D sharp interface ghost node immersed boundary method (IBM) within a fluid solver based on the compressible Navier–Stokes equations is underway. The objective of the IBM is to accurately apply boundary ... -
Fluid-Structure Interaction and Immersed Boundary Method for the Compressible Navier–Stokes Equations Using High Order Methods
Khalili, Ehsan (Doctoral theses at NTNU;2018:30, Doctoral thesis, 2017)There has been a growing interest in the study of biological flows in biomechanical systems in recent years. Such flows mostly appear in domains with complex geometries, flexible moving boundaries and usually involve ... -
High-order ghost-point immersed boundary method for viscous compressible flows based on summation-by-parts operators
Khalili, Mohammadtaghi; Larsson, Martin; Müller, Bernhard (Journal article; Peer reviewed, 2019)A high‐order immersed boundary method is devised for the compressible Navier‐Stokes equations by employing high‐order summation‐by‐parts difference operators. The immersed boundaries are treated as sharp interfaces by ... -
Immersed boundary method for the compressible Navier-Stokes equations using high order summation-by-parts difference operators
Khalili, Mohammadtaghi; Larsson, Martin; Müller, Bernhard (Chapter, 2017)A ghost-point immersed boundary method is devised for the compressible Navier–Stokes equations by employing high order summation-by-parts (SBP) difference operators. The immersed boundaries are treated as sharp interfaces ... -
Immersed boundary method for viscous compressible flows around moving bodies
Khalili, Mohammadtaghi; Larsson, Martin; Müller, Bernhard (Journal article; Peer reviewed, 2018)A ghost-point immersed boundary method for the compressible Navier–Stokes equations with moving boundaries on fixed Cartesian grids is devised by employing high order summation-by-parts (SBP) difference operators. The ... -
Interaction between a simplified soft palate and compressible viscous flow
Khalili, Mohammadtaghi; Larsson, Martin; Müller, Bernhard Theodor (Journal article, 2016)Fluid–structure interaction in a simplified 2D model of the upper airways is simulated to study flow-induced oscillation of the soft palate in the pharynx. The goal of our research has been a better understanding of the ... -
Numerical Modeling of Fluid-Structure Interaction in the Human Larynx
Larsson, Martin (Doktoravhandlinger ved NTNU, 1503-8181; 2010:155, Doctoral thesis, 2010)This thesis presents a method for fluid-structure interaction in a simplified 2D model of the human larynx using the arbitrary Lagrangian–Eulerian (ALE) approach and a strictly stable high order finite difference method. ...
