In this paper, a numerical study is conducted in order to compare hyperbolic range of equations of isotherm two-fluid model governing on two-phase flow inside of pipe using conservative Shock capturing method. Differential equations of the two-fluid model are presented in two forms (i.e. form I and form II). In forms I and II, pressure correction terms are hydrodynamic and hydrostatic, respecti...

This paper focuses on a survey of experimental data related to radiation into CO2 plasma flows, which are encountered during Mars and Venus entries. The review emphasizes VUV IR radiation, since recent efforts has been devoted these wavelength ranges they contribute mostly radiation. main objective the study is identify most attractive datasets for future crosscheck comparisons with results obt...

The development of a shock-induced detonation driver for enhancing the performance of a shock tube is described. The detonation wave is induced by the expansion of helium or air. Various gaseous fuel–oxidizer combinations are examined. This method produces a detonation wave which propagates downstream that transitions into a shock wave in the driven section. High-enthalpy flows with a maximum t...

Reports and Memoranda No. 332±* t February, z96z Summary. Apparatus is described for the measurement of shock attenuation.in channels of several configurations. A circular-bore channel, a square-bore channel and converging and diverging channels have been investigated. Measurements of hot-flow duration and wall pressure variations in the shock tube have also been made. It is concluded that conv...
