Resumen
Hypersonic flow of Mach number 8 past a 25°-50° double cone geometry is numerically simulated at ReD=4.8E5. Complicated flow structures, including Type V shock-shock interaction, shock-boundary layer interaction, separation and reattachment at the corner are presented and discussed. The surface pressure and heat transfer rate distributions are also calculated and compared with the experimental data. Results show that both the 2nd order MUSCL and 5th order WENO could accurately reproduce the shock structures, while the higher order scheme could predict a more accurate size of separation zone. Generally, the size of the separation zone is underestimated with an overvalued pressure distribution after reattachment employing the full turbulent models. On the other hand, transition induced by the reattachment shock has been calculated using transition model and the results of pressure peak and the size of separation zone show good agreement with the experimental measurements.

Resumen
This research based on a new type of Double-cone flow sensor, using computational fluid dynamics (CFD) method and orthogonal experiment to investigate the influence of key geometric factors, such as fore-and-aft cone angle, equivalent diameter ratio and channel flow length, on discharge coefficient, discharge coefficient linearity and relative pressure loss of double-cone flow sensor, and finally predict the best optimal match of these geometric factors. The turbulence model is RNG and the medium for simulation is water. After the simulation, a special device for calibration was set up to verify the computational conclusion. The results show that the biggest deviation of simulation on discharge coefficient linearity and relative pressure loss are less than 0.4% and 1.2%, the results simulated by CFD are in good agreement with that by experiment.

Resumen
Based on the principle of independence of cavity sections expansion, a double disc cavitator for underwater projectiles is proposed in this paper.The high-speed water tunnel experiment is carried out to study the generation and morphological characteristics of the ventilated supercavity which generated by this series of double disc cavitator.The experiment observed the ventilated supercavity morphology under the different cone angles by changing the ventilation flow coefficient.The experimental results show that there are two kinds of cavitation states:the front disc preferential cavitation and the rear disc preferential cavitation. The transition between these two states occur at a cone angle about 55°.The value of the critical ventilation flow coefficient when generating stable ventilation supercavity has a positive correlation with the cone angle.The front disc and the rear disc of the cavitator have mutual inhibitory effect on the production of ventilated supercavities.And the morphological characteristics of ventilated supercavity do not increase with the increasing of ventilation flow coefficient, but there is an upper limit value of ventilation flow coefficient.

Resumen
AbstractAn experimental study of double cone geometries in hypersonic flow (at M∞of 8·2 and Redof 0·36 × 106) was performed to provide additional data to a computational simulation study. In this study, depending on how the flow was initialised, the numerical solution yielded a violent pulsation mode of instability or a steady flow. Finally, an analysis of the shock oscillation was made and discussed.

Resumen
Direct simulation Monte Carlo (DSMC) of shock interaction in hypersonic low density flow is developed. Three collision molecular models, including hard sphere (HS), variable hard sphere (VHS), and variable soft sphere (VSS), are employed in the DSMC study. The simulations of double-cone and Edney’s type IV hypersonic shock interactions in low density flow are performed. Comparisons between DSMC and experimental data are conducted. Investigation of the double-cone hypersonic flow shows that three collision molecular models can predict the trend of pressure coefficient and the Stanton number. HS model shows the best agreement between DSMC simulation and experiment among three collision molecular models. Also, it shows that the agreement between DSMC and experiment is generally good for HS and VHS models in Edney’s type IV shock interaction. However, it fails in the VSS model. Both double-cone and Edney’s type IV shock interaction simulations show that the DSMC errors depend on the Knudsen number and the models employed for intermolecular interaction. With the increase in the Knudsen number, the DSMC error is decreased. The error is the smallest in HS compared with those in the VHS and VSS models. When the Knudsen number is in the level of 10−4, the DSMC errors, for pressure coefficient, the Stanton number, and the scale of interaction region, are controlled within 10%.

Resumen
Unsteady compressible flows typically pose problems with rich dynamics. The broad concern of this thesis is the shock wave unsteadiness that arises in external high-speed flow over a double-cone body. This unsteadiness is driven by complex interaction between the shock wave and the region of high shear and separation in the external flow. It is well known that the canonical double-cone problem exhibits two different classes of unsteadiness, labeled “pulsations” and “oscillations.” The former is characterized by unsteady shock wave motion over large spatial scales, whereas in the latter the nature of unsteadiness is distinct and occurs at a relatively smaller scale. The detailed mechanisms that sustain pulsations and oscillations are yet to be completely understood. In the present work, experiments were performed in the Roddam Narasimha Hypersonic Wind Tunnel (RNHWT) at Mach 6 to carefully investigate the phenomena of oscillations. Time-resolved schlieren and wall pressure data were obtained for various double-cone models with the second cone angle fixed at 90◦, while the first cone angle and ratio of the slant lengths were varied as parameters. Schlieren data revealed two dissimilar types, or modes, of flow oscillations. Spectral proper orthogonal decomposition (SPOD) analysis performed on experimental data showed the existence of a dominant time scale for the oscillations, and also provided the associated low-rank dynamics. The two different oscillation modes are found to exhibit distinct Strouhal number scaling. Given the direct dependence of shock strength on the flow Mach number (M ), the boundaries of unsteady flow states are expected to show slight changes with M. However, qualitative flow features and the underlying mechanisms that drive unsteadiness are expected to remain the same. Overall, this work reveals new flow behavior and furthers our understanding of the double-cone flow.
