Attractive colloidal particles can exhibit a fluid to solid phase transition if the magnitude of the attractive interaction is sufficiently large, if the volume fraction is sufficiently high, and if the applied stress is sufficiently small. The nature of this fluid to solid transition is similar for many different colloid systems, and for many different forms of interaction. The jamming phase t...

Pressure and temperature differences within screw compressors cause the various components to distort. The analytical methods currently used to predict the distortion of the components are insufficiently accurate to account for the complexity of the processes within these machines. Accordingly, in order to avoid rotor contact and seizure, the design clearances normally selected are larger than ...

Numerical modeling of machining processes is of significance in the parametric analysis and optimization of their performance. In this paper, a finite element-based model of abrasive waterjet (AWJ) cutting of a ductile material is presented with the help of an explicit, nonlinear finite element method. In this model, both solid-solid interaction and fluid-structure interaction are considered. T...

We propose a novel three-way coupling method to model the contact interaction between solid and fluid driven by strong surface tension. At heart of our physical is thin liquid membrane that simultaneously couples both volume rigid objects, facilitating accurate momentum transfer, collision processing, tension calculation. This implemented numerically under hybrid Eulerian-Lagrangian framework w...

A strongly coupled algorithm is presented for the incompressible fluid–rigid body interaction using moving immersed boundary method. The pressure and force are treated as Lagrange multipliers to enforce incompressibility no-slip wall constraints. To compute two unknowns from velocity field, we adopt fractional step successively apply Poisson equation a derived force, respectively. As both coeff...

Abstract The work concerns dynamic similarity criteria of various phenomena occurring in aerodynamics buildings and structures, hydraulics fluid dynamics derived from ratios forces moments affecting these phenomena. It consists three parts. Part I the bases formulated such a way relations to problems fluid–solid interaction at different relative motions. At end this part, authorial method proce...

In this paper, we present a new numerical method, the Immersed Element-Free Galerkin Method (IEFGM), for the solution of fluid-structure interaction problems. The technique is a variation of the Immersed Finite Element Method developed by (L. Zhang et al., Journal of Fluids and Structures, 23(6):836-857 (2007)) in which the fluid-solid interaction force is represented as a volumetric force in t...
