This work provides a novel approach that combines computational fluid dynamics (CFD) with solid mechanics (CSM) to dynamically simulate the fully coupled hydroelastic interaction between nonlinear ocean waves and submerged horizontal plate breakwater (SHPB). Based on systematic series of simulations, it is shown wave damping performance an SHPB can be evidently improved by appropriate extent de...

The effect of a hole on uplifting forces acting submerged horizontal thin plate are examined using the boundary element method. To deal with case, which is degenerate problem, hypersingular integral equation employed to overcome some troubles when method used. Two-dimensional problems considered, and linear gravity wave theory adopted. Several examples calculated numerical results presented sho...

Stable water-in-oil emulsion is essential to digital PCR and many other bioanalytical reactions that employ droplets as microreactors. We developed a novel technology to produce monodisperse emulsion droplets with high efficiency and high throughput using a bench-top centrifuge. Upon centrifugal spinning, the continuous aqueous phase is dispersed into monodisperse droplet jets in air through a ...

Experiments show that the amplitude of turbulent pulsation in submerged jets rises with increasing distance from the nozzle, at first slowly and then, after a certain distance, rapidly. This dependence on distance from the nozzle closely resembles the dependence of an order parameter on temperature in the case of a second-order phase transition. Following an idea introduced by Landa and Zaikin ...

Designing and manufacturing the multiple jets simulator and experimental investigation of the multiple jets in crossflow at low velocity ratios have been studied Together with design and build a low-speed wind tunnel. A specific rake is used to determine the flow field pressure and changes in static pressure measured by pressure taps in the near field of the jets. There are generally three regi...

Based on the results of applying the extended ADC emission model to three Z-track sources: GX 340+0, GX 5-1 and Cyg X-2, we propose an explanation of the Z-track sources in which the Normal and Horizontal Branches are dominated by the increasing radiation pressure of the neutron star. The emitted flux becomes several times super-Eddington at the Hard Apex and Horizontal Branch and we suggest th...
