Mean flow boundary layer effects of hydrodynamic instability of impedance wall
Abstract The Ingard–Myers condition, modelling the effect of an impedance wall under a mean flow by assuming a vanishing boundary layer, is known to lead to an ill-posed problem in time-domain. By analysing the stability of a mean flow, uniform...

A Second-order Diagonally-Implicit-Explicit Multi-Stage Integration Method
Abstract Implicit-explicit time stepping methods have proved useful for effciently solving problems with both still and nonstill components. IMEX Runge-Kutta methods and IMEX multistep methods have been studied in the literature. But there are no...

Analysis of Heat and Mass Transfer on MHD Flow of a Nanofluid Past a Stretching Sheet
Abstract In this work, a variational technique is applied to MHD, radiative nanofluid flow over a non-isothermal stretching sheet with Brownian motion and thermophoresis effects by Gyarmati's principle. The heat and mass transfer effects have been...

Combination of an adaptive multilevel SQP method and a space-time adaptive PDAE solver for optimal control problems
Abstract We present an adaptive multilevel generalized SQP method to solve PDAE-constrained optimization problems. It explicitly allows the use of independent integration schemes such that all involved systems can be solved highly efficient and as...

3D hp-Adaptive Finite Element Simulations of a Magic-T Electromagnetic Waveguide Structure
Abstract This paper employs a 3D hp self-adaptive grid-refinement finite element strategy for the solution of a particular electromagnetic waveguide structure known as Magic-T. This structure is utilized as a power divider/combiner in communication...

Boundary conditions for hyperbolic systems of partial differentials equations
Abstract An easy-to-apply algorithm is proposed to determine the correct set(s) of boundary conditions for hyperbolic systems of partial differential equations. The proposed approach is based on the idea of the incoming/outgoing characteristics and...
