Numerical methods were utilized to investigate the time-dependent flow patterns and the frequency characteristics of unsteady tip clearance flow in an axial-flow low-speed isolated compressor rotor.

Time dependent calculation for a suddenly imposed pressure gradient has shown that variation of the cross sectional area reduces inertial effect in the contraction flow region.

Objective To explore the changes of time-dependent pulmonary artery structural remodeling in pulmonary hypertension induced by high pulmonary flow in rats.
