In this talk, we deal with a simplified version of chemically reactive multi-species hypersonic flow around a cylinder. For this purpose, it is assumed that the flow environment only consists of nitrogen gas (N2), and no chemical reaction takes place in the flow field. Furthermore, the flow is assumed to be inviscid. A stabilized method is needed to prevent the numerical oscillations caused by the advection terms in the governing equations. Beyond that, a shock-capturing method is needed to obtain good solution profiles at the shocks. In this study, we use the compressible-flow Streamline-Upwind/Petrov-Galerkin method, complemented with the Y Zβ shock-capturing. The zero-normal-velocity condition on the cylinder is enforced weakly. Numerical simulations are carried out in the FEniCS ecosystem for both supersonic and hypersonic freestream conditions.

A Stabilized Finite Element Formulation for Numerical Simulation of Convection-dominated Reactive Models Cengizci, Süleyman; Uğur, Ömür; Srinivasan, Natesan (2020-10-15) In this talk, we are interested in the numerical solution of convection-dominated models with nonlin ear reaction mechanisms. The existence of the advection term(s) in the relevant models causes the numerical solutions obtained by standard methods to exhibit nonphysical oscillations. Therefore, the Galerkin finite element method (GFEM) is stabilized using the Streamline-Upwind/Petrov-Galerkin (SUPG) technique to prevent spurious oscillations. Moreover, the stabilized formulation is enhanced by the YZβ s...
An empirical method for the second viral coefficients of non-standard fluids Kis, Konrad; Orbey, Hasan (Elsevier BV, 1989-9) A new empirical method is proposed for the extension of Pitzer-Curl type correlations of the second virial coefficient to non-standard fluids as define
A new boundary element formulation for wave load analysis Yalcin, O. Fatih; Mengi, Yalcin (Springer Science and Business Media LLC, 2013-10-01) A new boundary element (BEM) formulation is proposed for wave load analysis of submerged or floating bodies. The presented formulation, through establishing an impedance relation, permits the evaluation of the hydrodynamic coefficients (added mass and damping coefficients) and the coefficients of wave exciting forces systematically in terms of system matrices of BEM without solving any special problem, such as, unit velocity or unit excitation problem. It also eliminates the need for scattering analysis in ...
A robust algorithm for configurational-force-driven brittle crack propagation with R-adaptive mesh alignment MIEHE, CHRISTIAN; Gürses, Ercan (2007-10-08) The paper considers a variational formulation of brittle fracture in elastic solids and proposes a numerical implementation by a finite element method. On the theoretical side, we outline a consistent thermodynamic framework for crack propagation in an elastic solid. It is shown that both the elastic equilibrium response as well as the local crack evolution follow in a natural format by exploitation of a global Clausius-Planck inequality in the sense of Coleman's method. Here, the canonical direction of the...
A frequency domain boundary element formulation for dynamic interaction problems in poroviscoelastic media Argeso, Hakan; Mengi, Yalcin (2014-02-01) A unified formulation is presented, based on the boundary element method, to perform the interaction analysis for the problems involving poroviscoelastic media. The proposed formulation permits the evaluation of all the elements of impedance and input motion matrices at a single step in terms of system matrices of boundary element method without solving any special problem, such as, unit displacement or load problem, as required by conventional methods. It further eliminates the complicated procedure and th...
