Radial Gas Profiles in Vertical Pipe Flow in Dependence on the Bubble Size Distribution


Radial Gas Profiles in Vertical Pipe Flow in Dependence on the Bubble Size Distribution

Lucas, D.; Krepper, E.; Prasser, H.-M.

The paper presents a method for the prediction of the radial gas profile in vertical pipe flow for a given bubble size distribution. The method assumes equilibrium of the forces acting on a bubble perpendicular to the flow direction. On basis of the radial profile of the liquid velocity, radial distributions of the volume fraction are calculated separately for all bubble classes according to a given bubble size distribution. The sum of these distributions is the radial profile of the gas fraction. The model is the basis of a fast running one-dimensional steady state computer code. The results of the model are compared with experimental data for a number of gas and liquid volume flow rates.
