Experimental Investigation of the Effect of Purge Flow and Main Flow Interaction in a Low-Speed Turbine Cascade Passage [PDF]
Entropy, 2020 In order to protect the vulnerable turbine components from extreme high temperature, coolant flow is introduced from the compressor to the disk cavity, inevitably interacting with the main flow.

International Journal of Turbomachinery, Propulsion and Power, 2023 The efficiency assessment of a high-pressure turbine (HPT) stage is complicated by the presence of upstream and downstream purge flows. In fact, the efficiency calculation is often based on mass flow-averaged values of total temperature at the stage ...

Periodic Flow Purging System for Harvesting Fibers from Screens [PDF]
Aerosol and Air Quality Research, 2021 Abstract Fiber length is believed to be an important factor in determining various toxicological responses to asbestos and other bio-persistent fibers. Length classification of fibers thus is crucial for toxicological assessment. Nylon mesh screens have been shown to be effective in separating fibers by length.

Mass Purging of Stale TCP Flows in Per-Flow Monitoring Systems [PDF]
2009 Proceedings of 18th International Conference on Computer Communications and Networks, 2009 Timely deletion of a large number of stale sessions monitored by Internet routers, particularly in the presence of SYN floods, is critical to prevent flow table explosion. We investigate two frameworks for purging of stale sessions: "oppor- tunistic" purging that employs a free-list of pointers to memory and "deterministic purging" involving logical ...
