Effect of Eccentric Mass Distribution on the Motion of Spherical Particles in Shear Flows
(The American Society of Mechanical Engineers (ASME), 2020)A particle-resolved direct numerical simulation is performed on the motion of spherical particles with an eccentric internal mass distribution in lateral linear shear flow, which is oriented in the vertical direction and ... -
Effect of Runner Blade Thickness on Flow Characteristics of a Francis Turbine Model at Low Flowrates
(The American Society of Mechanical Engineers (ASME), 2020)Francis turbines are often used for generating hydroelectric power, but their performance characteristics significantly depend on the operating conditions. In particular, interblade vortices in the passages between runner ... -
Theoretical Analyses of the Number of Backflow Vortices on an Axial Pump or Compressor
(The American Society of Mechanical Engineers (ASME), 2020)Backflow vortices occasionally occur in the annular mixing zone between the main and axially reverse whirling flows from the impeller tip clearance on an axial pump or compressor. A number (N) of tornado-like backflow ... -
On the Influence of Gas Content on the Rotordynamic Force Coefficients of a Three-Wave (Air in Oil) Annular Seal for Multiple Phase Pumps
(The American Society of Mechanical Engineers (ASME), 2020)Subsea multiphase pumps must operate reliably with a process fluid transitioning from a pure liquid, to a mixture of gas and liquid, and to eventually just gas; and pressure seals controlling secondary leakage paths are ... -
Experimental Analysis of Gas–Liquid Flows in a Centrifugal Rotor
(The American Society of Mechanical Engineers (ASME), 2020)This work presents an experimental analysis of gas–liquid flows in a centrifugal rotor prototype. Pressure rise curves are evaluated considering a wide range of liquid and gas flowrates and different rotating speeds. An ... -
