摘要:Abstract(#br)A mathematical model is developed for the analysis of spatially varied steady flow in irrigation canals. The model accounts for canal seepage and effect of control structures at the upstream and downstream ends of the canal. Two computational methods developed to sol...

摘要:Abstract(#br)In this paper, a novel design of a rotary hydraulic flow control valve has been presented for high flow rate fluid power systems. High flow rates in these systems account for substantial flow forces acting on the throttling elements of the valves and cause the applic...

摘要:... It is found that a steady flow in the form of a system of nested fluid columns of circular cross section, which rotate at different angular velocities, is generated in the cavity as a result of oscillations of the core and the fluid. It is shown that at simultaneous influenc...

摘要:Abstract(#br)The fluid flow in a non-uniformly rotating (librating) cylinder about a horizontal axis is experimentally studied. In the absence of librations the fluid performs a solid-body rotation together with the cavity. Librations lead to the appearance of steady zonal flow i...

摘要:Abstract(#br)In this paper, a servo motor operated rotary directional control valve is proposed, and a systematic analysis of steady flow torques in this valve is provided by theoretical calculation, CFD simulation and experimental test. In the analysis, spool rotation angle c...

摘要:Abstract(#br)The aim here is to model the standing torsional oscillations in solar spicules in the presence of density stratification, magnetic field expansion, and steady flows. By implementing cylindrical geometry, the eigenfrequencies, eigenfunctions, and the period ratio \(P_...

摘要:Abstract(#br)Results of a physical modelling study of clear-water scour at a tripod obstacle in uniform bed sediment under steady flow conditions are presented. 4 flow depths, 2 flow velocities and 3 angles of attack were considered. Maximum scour depth increased with increase...

摘要:Abstract(#br)In this paper, a simulation of the steady flow in a pipe of square cross-section has been performed when the pipe is filled with a Bingham fluid. The problem has been solved employing the Bingham model without any regularisation. An innovative approach based on a mo...

摘要:... For this issue, frequency domain analysis methods with and without incorporation of local steady flow effects are developed to investigate wave loads and free motions of two parallel ships advancing in waves, which are based on analytical quadrature of the Bessho form transla...

摘要:Abstract(#br)We study steady flow of a second grade fluid past an obstacle in three space dimensions. We prove existence of solution in weighted Lebesgue spaces with anisotropic weights and thus existence of the wake region behind the obstacle. We use properties of the fundamen...
