Accurate modeling of contamination in subsurface flow and water aquifers is crucial for agriculture environmental protection. Here, we demonstrate a parallel algorithm to quantify the propagation uncertainty dispersal pollution flow. Specifically, consider density-driven estimate how from permeability porosity propagates solution. We take two-dimensional Elder-like problem as numerical benchmar...

The flow in sewers is a complete three phase flow (air, water and sediment). The mechanism of sediment transport in sewers is very important. In other words, the passing flow must able to wash deposited sediments and the design should be done in an economic and optimized way. In this study, the sediment transport process in sewers is simulated using a hybrid model. In other words, using the Ada...

In this paper, the cooling performance of water-cooled heat sinks for heat dissipation from electronic components is investigated numerically. Computational Fluid Dynamics (CFD) simulations are carried out to study the rectangular and circular cross-sectional shaped heat sinks. The sectional geometry of channels affects the flow and heat transfer characteristics of minichannel heat sinks. T...

in this paper, a genetic algorithm is presented for an identical parallel-machine scheduling problem with family setup time that minimizes the total weighted flow time ( ). no set-up is necessary between jobs belonging to the same family. a set-up must be scheduled when switching from the processing of family i jobs to those of another family j, i  j, the duration of this set-up being the sequ...

The present work considers the Struma River water flow on Bulgarian territory as a starting point for evaluation of maximum and minimum water flow using an original integral method. The risk assessment is determined by specific indices like the index Mmax,i for the deviation of the maximum water flow from the calculated norm of the maximum flow Qmax,0 and the index Mmin,i for the deviation of t...

This paper addresses a new mixed integer nonlinear and linear mathematical programming economic lot sizing and scheduling problem in distributed permutation flow shop problem with number of identical factories and machines. Different products must be distributed between the factories and then assignment of products to factories and sequencing of the products assigned to each factory has to be d...

Figure 2: Phantom images and separated fat-only and water-only images for (a) FTED, (b) nulling at RF, (c) nulling at the echo center. Flow-artifacts are effectively reduced in (b) and (c). Note that water tube in (a) and (b) was incorrectly separated into the fat-only image because the existing region growing algorithm cannot handle disconnected objects. (c) (b) (a) Flow Compensation in Freque...

The fluid flow and heat transfer in a three-dimensional microchannel filled with Al2O3- water nanofluid is numerically investigated. The hybrid scheme is used to discretize the convection terms and SIMPLER algorithm is adopted to couple the velocity and pressure field in the momentum equations. The thermal and flow fields were analyzed using different volume fractions of n...
