A statistical particle path tracking method is applied to a hollow rotating detonation engine (RDE) with Laval nozzle, and the flow field characteristics are investigated. The in-house solver BYRFoam based on OpenFOAM used, large-area outflow at tail of combustor an array injection holes implemented. influence mechanism nozzle internal external fields RDE revealed. results confirm that helps su...

In earlier studies of acoustic scattering resonances and of the dispersive phase velocities of surface waves that generate them [see, e.g., Talmant et al., J. Acoust. Soc. Am. 86, 278-289 (1989) for spherical aluminum shells] we have demonstrated the effectiveness and accuracy of obtaining phase velocity dispersion curves from the known acoustic resonance frequencies. This possibility is offere...

In this paper, we study the wave transport and localization properties of novel aperiodic structures that manifest intrinsic complexity prime number distributions in imaginary quadratic fields. particular, address structure-property relationships scattering through elements nine fields (i.e., their associated rings integers) with class one, which are unique factorization domains (UFDs). Our the...

This paper describes the effects of induced magnetic field and partial slip on the peristaltic flow of a couple stress fluids in an asymmetric channel. The two dimensional equation of couple stress fluid are simplified by making the assumptions of long wave length and low Reynolds number. The exact solutions of reduced momentum equation and magnetic force function have been computed in wave...

Segments of dog carotid artery were held at in-situ length and studied in vitro after excitation of the muscle with norepinephrine and after poisoning of the muscle with potassium cyanide. In-situ length corresponded to a longitudinal strain of .57 ± .02 relative to the unstretched length. The longitudinal elastic modulus was about 4.1 X 10 dyn/cm at in-situ length and zero transmural pressure....
