ffects of pressure ratio and rotational speed on the leakage flow nd cavity pressure characteristics of the rotating staggered labyinth seal were investigated by means of experimental measureents and numerical simulations. The rotating seal test rig with urbine flowmeter and pressure measuring instruments was utiized to investigate the leakage flow of the staggered labyrinth eal at eight pressu...

In most cases, structural engineers assume a concrete floor to be a rigid diaphragm. Although this simplification is in most cases acceptable, it should be noted that such an assumption may be distrusted due to certain problems. Concrete structures with staggered shear walls are among those whose analysis should be conducted with special concern for the behavior of their floor diaphragms. Howev...

In order to solve the problems of high millet agglomerates rate, damage and undelivered net loss rate in process mechanized harvesting millet, a longitudinal axial flow-staggered flexible threshing device for was designed on basis existing device. The “staggered teeth” drum micro rotating circular tube concave screen work together realize low millet. pre experiment carried out first, factors th...

The R algorithm is widely used for simulating two flavours of dynamical staggered fermions. We give a simple proof that the algorithm converges to the desired probability distribution to within O(δτ ) errors, but show that the relevant expansion parameter is (δτ/m), m being the quark mass. The Rational Hybrid Monte Carlo (RHMC) algorithm provides an exact (i.e., has no step size errors) alterna...

The synchronous tuning of the self-oscillating wireless power transfer (WPT) in a close-coupling condition is studied in this paper. The Hamel locus is applied to predict the self-oscillating points in the WPT system. In order to make the system operate stably at the most efficient point, which is the middle resonant point when there are middle resonant and split frequency points caused by freq...

In this study the developed procedure of Advection in Volume of Fluid (VOF) method for free surface modeling is presented. Two-step projection method is implemented for solution of RANSE equations discretized by finite difference method on the staggered and Cartesian grids. Applying Youngs’ algorithm in staggered grids, assuming that fluid particles in the cell have the same velocity of the cel...
