An adaptive streamline diffusion finite element method for hyperbolic systems in gas dynamics

It has also become more and more evident that it is important to simulate the fluid on the computer numerically before experimenting in the laboratory. For the mathematicians this leaves the significant tasks of developing an efficient and reliable numerical method for solving the dynamical systems. The problems of fluid flow can usually be described by certain convection-dominated convection diffusion equations. For such type of equations some researcher proposed to use a numerical diffusion only in the convection direction to suppress the possible oscillations near the discontinuities of the solutions. Another researcher proceeded with the pointwise error analysis of the streamline diffusion method for a two-dimensional stationary problem with constant coefficients. In the present thesis the author will the pointwise error analysis to the time-dependent problems to justify of local mesh refinement strategy. Our results are valid for scalar as well as for certain system problems. In this paper the one-dimensional Euler equations coming from the shock tube and Riemann's problem in gas dynamics will serve as a model. Such a problem can arise for example in the case of a long, thin, cylindrical tube containing a gas separated by a thin membrane. Assuming that the gas is at rest on both sides of the membrane, but that pressure and density are different on each side.
