Cross-leakage flow between adjacent flow channels in PEM fuel cells

Journal of Power Sources, 2006
Abstract In polymer electrolyte membrane (PEM) fuel cells, serpentine flow channels are used conventionally for effective water removal. The reactant flows along the flow channel with pressure decrease due to the frictional and minor losses as well as the reactant depletion because of electrochemical reactions in the cells.

Leakage Detection in Subsea Flow Lines

Day 1 Mon, February 21, 2022, 2022
Abstract With hydrocarbon targets becoming more inaccessible and further away from the marketplace, the need for operative fault monitoring process for continuous pipeline operation is attracting renewed attention. Dependable evacuation process is essential in managing the volatile hydrocarbon products demand-supply drivers.

Modeling of the double leakage and leakage spillage flows in axial flow compressors

Journal of Thermal Science, 2014
A model to predict the double leakage and tip leakage leading edge spillage flows was developed. This model was combined by a TLV trajectory model and a TLV diameter model and formed as a function of compressor one-dimensional design parameters, i.e. the compressor massflow coefficient, ϕ and compressor loading coefficient, Ψ, and some critical blade ...

Analysis of total leakage of finger seal with side leakage flow

Tribology International, 2020
Abstract The flow through the finger interstices and the micro voids in rough contact interface between finger sticks is considered as the side leakage flow of finger seal. The porous approach that the side leakage flow of finger seal is transformed into the seepage flow through a porous medium was proposed.

Passive flow control of bileaflet mechanical heart valve leakage flow

Journal of Biomechanics, 2008
Blood damage and platelet activation are inherent problems with present day mechanical heart valve designs. We investigate the approach of passive flow control applied to bileaflet mechanical heart valve (BMHV) flows as a means of optimizing leakage flow hemodynamics at length scales relevant to blood damage and platelet activation.

Leakage Flow Over Shrouded Turbine Blades

Volume 3: Heat Transfer; Electric Power; Industrial and Cogeneration, 2000
In this paper the flows over shrouded turbine blades with single, double, and triple tip seals were simulated by using the two-dimensional Reynolds-averaged Navier-Stokes equations and a compressible k-ε turbulence model. A multi-zone technique was used to generate the grids in the complex flow channel.
