The flow of a dilute gas particle mixture entering a circular curved pipe was investigated. The fluid is assumed to incompressible and the flow nonseparating and laminar. Individual numerical schemes were devised to handle the two different regions of the fluid flow field, i.e. the irrotational core region and viscous boundary layer region, interaction between the two regions is also accounted for by means of a simple iteration scheme. Final results are presented and compared with other theoretical and experimental results. The dynamics of the particle phase are discussed. Lagrangian equations of motion for the particle phase are used. The first order solution for the particle phase was obtained and proved adequate in the erosion calculation of a curved pipe carrying a gas-solid mixture. Asymptotic expansion solutions for the particle trajectories are discussed. The density of the particle at the pipe wall is presented and the numerical results are discussed.
