Abstract: Various aspects of the disclosed technology relate to axial thrust analysis of turbomachinery designs. A cavity of a turbomachinery design is divided into sub-cavities. Magnitudes of horizontal components of forces exerted on rotational faces in each of the sub-cavities are computed based on computational fluid dynamics, areas of the rotational faces and angles of the rotational faces. The horizontal components are components along a rotational axis of the turbomachinery design. Directions of the horizontal components of the forces are determined based on how many faces a line parallel to the rotational axis intersects between a rotational face of interest and a side of the cavity. A thrust force on a turbine of the turbomachinery design attributed to secondary fluid systems is computed using the magnitudes and the directions of the horizontal components of the forces.
