dc.description.abstractThis thesis considers droplet-gas flow by the use of numerical methods and experimental verification. A commercial vane separator was studied, both numerically and by experiment. In addition, some efforts are put into the numerical analysis of cyclones. The experimental part contains detailed measurements of the flow field between a pair of vanes in a vane separator and droplet size measurements. LDA (Laser Doppler Anemometry) was used to measure the velocity in two dimensions and corresponding turbulence quantities. The results from the LDA measurements are considered to be of high quality and are compared to numerical results obtain from a CFD (Computational Fluid Dynamics) analysis. The simulations showed good agreement between the numerical and experimental results. Combinations of different turbulence models; the standard k-ε model and the Reynold Stress Model, different schemes; first order and higher order scheme, and different near wall treatment of the turbulence; the Law of the wall and the Two-Layer Zonal model, were used in the simulations. The Reynolds Stress Model together with a higher order scheme performed rather poorly. The resirculation in parts of the separator was overpredicted in this case. For the other cases the overall predictions are satisfactory.nb_NO
