A general, two-way coupled, point-particle formulation that accounts for the disturbance created by dispersed particles in obtaining undisturbed fluid flow field needed accurate computation of force closure models is presented. Specifically, equations presence are first derived based on inter-phase momentum coupling a finite-volume formulation. Solution to obtained using two approaches: (i) dir...

The propagation of hydrothermal waves in a differentially heated shallow open cavity filled with complex fluid (a mixture an oil solid spherical metallic particles) is investigated the framework hybrid numerical two-way coupled Eulerian–Lagrangian methodology. We explore response this system to mass fraction (mass load) and particle size (Stokes number). results show that particles related (ine...

We have experimentally realized unidirectional or one-way coupling in a mechanical array by powering the coupling with flowing water. In cyclic arrays with an even number of elements, solitonlike waves spontaneously form but eventually annihilate in pairs, leaving a spatially alternating static attractor. In cyclic arrays with an odd number of elements, this alternating attractor is topological...

In this paper, a planar three-way power divider with compact size is presented using quarter-wave long five-conductor couple line. It is analytically proved that the proposed structure allows the performance of three-way power dividers. Based on the derived equations and simulation, the three-way power divider is designed and measured at 2.0GHz. The measurement shows excellent performance with ...

Purpose Simulations exist for the prediction of behaviour building structural systems under fire, including two-way coupled fire-structure interaction. However, these simulations do not include detailed models connections, whereas connections may impact overall structure. Therefore, this paper proposes a two-scale method to screw connections. Design/methodology/approach The consists (a) global-...

this study investigated the performance and aeroelastic characteristics of a wind turbine blade based on strongly coupled approach (two-way fluid structure interaction) to simulate the transient fsi1 responses of hawt2. aerodynamic response was obtained by 3d cfd-urans approach and structural response was obtained by 3d finite element method. aeroelastic responses of the blade were obtained by ...

Over the years, Nigeria depends on crude oil proceeds as the major source of national income, foreign exchange and external reserves. This dependence coupled with the huge cost of running and maintaining the political structure among other factors prove disastrous by leading the economy to the worst recession in decades. We therefore, chronicle the origin, effects and way out of the recession v...
