Critical Study on Incremental Static Analysis of 2D Flow, by Inter-Colliding Point-Particles, by Use of In-Compressible Rhombic Element | Chapter 5 | Recent Developments in Engineering Research Vol.5

 For incremental static analysis of a collection of inter-colliding particles, simulating 2D flow, a simple method is suggested. Numerical experiments show that the proposed approach converges to a final equilibrium state if the liquid is confined within the borders of a collection of inter-communicating vessels. As a first approximation to the 2D motion of a liquid, this incremental static analysis approximates dynamic behaviour with good damping and can provide data. A rhombic feature is suggested in the initial arrangement of particles, which ensures adequate in-compressibility of the fluid. A simple and short computer programme (a "pocket" programme) has been developed based on the proposed algorithm, with only about 120 Fortran instructions. Second, this software refers to a quantity of liquid stored in a single vessel. In the final liquid equilibrium state, the hydro-static distribution In a satisfactory approximation with corresponding theoretical data, pressure on vessel boundaries obtained by the proposed computational model is found. Then, at the bottom of the vertical boundary of the original vessel, an opening is created, and the liquid is allowed to flow gradually to the adjacent vessel. Almost the entire quantity of liquid is moved from the first to the second vessel, with the exception of a few drop-particles, which remain at the bottom of the initial vessel in equilibrium. In the final liquid equilibrium state, the free surface level of the liquid in the second vessel confirms that the proposed rhombic feature ensures the fluid 's satisfactory in-compressibility.
