Transient analysis of upstream wake inside turbine blade passage with purge flow

, 2020
Secondary air bled from the compressor which bypasses the combustion chamber is used to seal the turbine components from incoming hot gas. Interaction of this secondary air (also known as purge flow) with the mainstream flow can alter the flow ...

Anticoagulation of Impella with a Bivalirudin Purge Solution

ASAIO journal (1992), 2020
The use of percutaneous ventricular assist devices (VADs) in the acute management of cardiogenic shock is becoming increasingly common. The Impella is a percutaneous VAD, which requires a heparin-containing purge solution to prevent thrombosis and ...

Purge strategy optimization of proton exchange membrane fuel cell with anode recirculation

Applied Energy, 2018
Anode recirculation increases hydrogen utilization but also causes nitrogen crossover and accumulation in proton exchange membrane fuel cell (PEMFC) anode. Purge is necessary to remove the impurity.

A DEM-CFD study of the effects of size distributions and packing fractions of pebbles on purge gas flow through pebble beds

Fusion engineering and design, 2019
In a solid-type ceramic breeding blanket, the functional materials, such as the breeder, multiplier, and reflector, are equipped in the form of pebble beds, while helium purge gas flows through pebble beds.
