Numerical modeling of fluid flow around a bunch of balloons with different cross-sections

To analyze the behavior of fluids around obstacles cylinder to reduce costs, reduce the time to achieve the results and analysis of boundary conditions to the numerical simulation using FLUENT software Rvym.dr paper, Unsteady Flow, two-dimensional, incompressible intended for each Reynolds static pressure contours, Vorticity, flowing lines and speed has been obtained.It can be seen that the rectangular cylinder pressure at the inlet of the circular cylinders and more triangular and wherever is made of vortices And in which the pressure Darym.dr least the low pressure flow lines will be able to lose your makeup.Also generally at high Reynolds numbers for all cases, and in this case also during the more turbulent flow vortices more.The main gates of the high-pressure occur at these points there is no vortices and flow irregularities.It is known that the contours pressure cylinder with a rectangular cross-sectional area drag to endure more.
