dc.description.abstract |
In this work, pressure drop through sudden contraction in mini circular pipe have been numerically
investigated, using air and water as the working fluids at room temperature and near atmospheric
pressure. Numerical methods include the use of two-phase computational dynamics CFD
calculations based on VOF method were used to predict the pressure. The calculated pressure drop
is determined by extrapolating the computed pressure profiles upstream and downstream the
contraction. The tubes inside diameters are respectively 40 mm and 30 mm with a contraction ratio
of 0,567. The superficial velocities, investigated in this work, ranged for the gas from 0.54 to 5.5
m/s and for the liquid from 0.011 up to 0.24 m/s. The numerical results are validated against
experimental data from the literature and are found to be in good agreement |
