Bistability and Triggering Analysis of Thermoacoustic Instability in a Horizontal Rijke Tube
Xibei Gongye Daxue Xuebao, 2019 Dynamical systems theory has been often employed to study nonlinear flow and flame dynamics in combustion systems. However, the corresponding studies using nonlinear dynamics to analyze the Rijke tube thermoacoustic system are still occasional.

Research on Skin-Friction Drag Reduction by Hydrogen Injection in Supersonic Boundary Layer
Xibei Gongye Daxue Xuebao, 2019 In order to investigate the applicability of the skin-friction reduction technique using hydrogen injecting into turbulent boundary layer, three-dimensional numerical simulation was carried out for a constant-cross-confined-space with rearward facing ...

Applied Statistics, 1971 In most computer languages, the data are regarded as being held in machine storage either as individual scalar quantities or as members of rectangular arrays. It would make these languages more useful if the user were allowed to specify the shapes of other structures in which he wished to consider the data as being held, such as triangular arrays ...

Quantum Internal Structure of Plasmons [PDF]
Physical Review Letters, 2021 Plasmons are usually described in terms of macroscopic quantities such as electric fields and currents. However as fundamental excitations of metals they are also quantum objects with internal structure. We demonstrate that this can induce an intrinsic dipole moment which is tied to the quantum geometry of the Hilbert space of plasmon states. This {\it

A Model for Igniter Mass Flow Rate History Evaluation for Solid Rocket Motors
International Journal of Aerospace Engineering, 2019 This paper describes a zero-dimensional model for evaluating the mass flow rate history of a solid rocket motor igniter. Based on the results of an igniter-firing experiment, in which the igniter is the only source of combustion gas and no propellant is ...
