Numerical Analysis of Gun Barrel Pressure Blast Using Dynamic Mesh Adaption
… to simulate the unsteady flow using dynamic mesh with moving boundary. Most CFD based ballistics-model requires additional thermodynamic functions which must be derived from the Noble-Abel equation of state. The unsteady, axisymmetric Navier Stokes equation systems were numerically solved …

Dynamic mesh adaption for supersonic combustion waves modeled with detailed reaction mechanisms
Dynamic mesh adaption has emerged as a powerful tool to reduce the <br>numerical cost of CFD problems. We use this technique to resolve the <br>disparate physical scales of reactive flow problems. <br>In our numerical scheme, we combine the dynamic mesh adaption with <br>an explicit as well as …

Multi-dimensional Upwind Fluctuation Splitting Scheme with Mesh Adaption for Hypersonic Viscous Flow
… of the Navier-Stokes equations on unstructured meshes. Key features of the scheme are the compact stencil, full upwinding, and non-linear discretization which allow for second-order accuracy with enforced positivity. Throughout, the fluctuation splitting scheme is compared to a current …

Mathematical methods for the modelling of cell migration and chemotaxis
… flow is introduced in the form of a moving mesh partial differential equation (MMPDE). This MMPDE is split into two partial differential algebraic equations: one for the normal velocity and one for the tangential velocity. We examine curves moving with a prescribed normal velocity and this …

Development of an efficient 3-D CFD software to simulate and visualize the scavenging of a two-stroke engine
… local time-stepping and dynamic local mesh adaption, as well as parallelization of the code, are used to speed up the computation time considerably. <br>The software has been extensively validated and has been applied to the problem of short-circuiting in two-stroke engines.

Investigation of Scaling Effects for a Synthetic Jet Actuator Using High and Low Fidelity Analyses
… against referred publications. The use of mesh adaption is discussed. This baseline model was then used to complete a scaling analysis using a set of geometries. The average velocity and the thrust at the orifice were controlled values. The Lumped Element Model (LEM) was employed to create …
