Abstract: When irradiated by acoustic waves, gas bubbles can generate divergent spherical waves, which are frequently used to detect the sizes and number density of the gas bubbles. In this paper, a generalized equation for scattering ...

Abstract: Aerodynamic shape optimization plays a significant role during the conceptual design stage of hypersonic vehicles. In this study, an interval-robust optimization method is proposed for the design of hypersonic vehicles, ...

Abstract: Compliant contact force modeling has become a popular approach for contact and impact dynamics simulation of multibody systems. In this area, the nonlinear viscoelastic contact force model developed ...

Abstract: A three-dimensional single-point impact solution has been developed based on the original work of Keller. The formulation involves an integrated form of Keller’s equations and leads to a different ...

Abstract: Rectified mass diffusion serves as an important mechanism for dissolution or growth of gas bubbles under acoustic excitation with many applications in acoustical, chemical and biomedical engineering. In this paper, a general ...

Abstract: The fidelity of the interannual variability of precipitation over Nordeste is examined using the suite of the NCEP Climate Forecast System (CFS) seasonal hindcasts. These are coupled ocean?land?atmosphere multiseasonal ...

Abstract: During the spin-no-load mode, vibrational performance of the reversible pump turbine is an important criterion for the evaluation of the operational performances of the power station. In the present paper, the influences ...

Abstract: The conventional practice of calculating consolidation settlement in one-dimensional conditions involves dividing soft ground into multiple layers to enable an accurate estimation. However, the effect of layering on ...

Abstract: Frictional heating of a thermal mound (or hot spot) present on the interface between a carbon graphite block sliding against a fast moving conductor is simulated. Heating of this mound due ...
