| Summary: | 碩士 === 國立成功大學 === 航空太空工程學系 === 86 === The purpose of the study is to investigate the problems of
2-D airfoil in hypersonic viscous flow field, such as the
pressure、density and temperature before and after region of the
bow shock, and the aerodynamic heating problem on the airfoil.
The NACA-0012 airfoil is used to build grids. The minimod total
variation diminishing (TVD) algorithm is applied in the scheme
which is constructed in finite-volume method. The initial and
boundary conditions were employed to solve the Navier-Stokes
equation to get the density、velocity、total energy and
pressure. Then the Tannehill's curve fitting method was used for
computing the temperature. Finally, the Hansen's high
temperature gas property tables are employed to correct the
specific heat ratio、conductivity coefficient、speed of sound
and Prandtl number of the air.
