The Eulerian formulation for the two-phase flow problem is simpler in the theoretical structure and more economical in the computational time than the Lagrangian formulation. However the boundary conditions on the center axis of symmetry give a difficulty with explaining the physical phenomena on the axis. Hence in the nozzle and jet flows the Lagrangian way of calculations is applied for the solid phase to avoid the boundary problems. The numerical results of the solid particle flow of a nozzle and jet simulate an experimental result to validate the developed code.departmental bulletin paperFaculty of Engineering, Nagoya University1989-03-31application/pdfMemoirs of the Faculty of Engineering, Nagoya University2403513620027-7657https://nagoya.repo.nii.ac.jp/record/30740/files/40-2-06.pdfeng
