A numerical study of the thermal and fluid-dynamic behaviour of the two-phase flow in conducts is presented. The numerical analysis is based on two-fluid models. The model allows consider that liquid and gas have different velocities and temperatures. The numerical simulation has been developed by means of the finite volume technique based on a one-dimensional transient integration of the conti...

Simulation of natural phenomena is one of the important research fields in computer graphics. In particular, clouds play an important role in creating images of outdoor scenes. Fluid simulation is effective in creating realistic clouds because clouds are the visualization of atmospheric fluid. In this paper, we propose a simulation technique, based on a numerical solution of the partial differe...

a meshless method namely, discrete least square method (dlsm), is presented in the paper for the solution of free surface seepage problem. in this method computational domain is discredited by some nodes and then the set of simultaneous equations are built using moving least square (mls) shape functions and least square technique. the proposed method does not need any background mesh therefore ...

 This paper is concerned with numerical simulation of plastic modes of tubular structures. The simulation incorporates with finite element limit analysis based on the upper bound method and the minimization technique. The analysis considers sequential deformation of structures with work-hardening effects. The simulation results demonstrate plastic buckling is one of the collapse modes and occu...

a boundary integral method is used to simulate spilling breakers. the bottom is also included inthe introduced closed boundary and the problem is directly solved in the physical plane. the method has beenshown to be remarkably stable, and no numerical instability has occurred in any of the calculations. theresults reveal that both the momentum and total energy are almost constant in time during...
