Experimental Analysis of Flow Through Throttle Valve During Gaseous Cavitation

Investigation of the Flow and Cavitation in a Butterfly Valve

Since knowledge on hydrodynamic torque of a butterfly valve is very important for butterfly valve design, its hydrodynamic torque is investigated in this paper. In reality, the investigation of the loss coefficient and torque from some experiments will take a long time and a lot of money. This paper presents a statistical study of the flow past the butterfly valve in a static analysis using com...

Flow Optimisation through Porous Ceramic Throttle

Dynamics of fluids in porous media is of importance in many fields of practical interest. Currently scientists at the Medical Sensors and Devices Laboratory at the Luebeck University of Applied Sciences are developing a throttle system for a gas-driven infusion device whose centrepiece consists of a nanoporous ceramic unit for regulating the flow in the range of microto nanoliters per minute. A...

Experimental investigation of flow through a bileaflet mechanical heart valve

Turbulent flow downstream of a bileaflet mechanical heart valve is investigated using digital particle image velocimetry. Evolution of flow structures during the systole and diastole phases of a typical cardiac cycle is characterized by obtaining global flow velocity measurements in multiple cross-sections of the flow field. Instantaneous and time-averaged patterns of flow velocity, vorticity, ...
