| Summary: | 碩士 === 輔仁大學 === 數學系 === 83 === The first purose of study is to investigate about the process
of the fixed boundary for hyperbolic equations. There is a
especial method be to make use of the nature of the
characteristic curve with the first-order space extrapolation
method. This method considers that the flow is the subsonic or
supersonic,respectively. And it discusses the process of the
boundary for the inflow and outflow. By the numerical results,
this method is avilable for the fixed boundary. The second
purose of study is to investigate about the process of the
moving boundary for the piston problem. The Reflection method
is to make use of the process of the moving boundary for the
general schemes. A physically motivated wall boundary treatment
is to make use of the expand cell scheme. We can get a better
result from considering the expand cell scheme by the
comparisons of numerical results.
