Contribution to Tip Leakage Loss Modeling in Radial Turbines Based on 3D Flow Analysis and 1D Characterization [PDF]
, 2019 [EN] The characterization of tip leakage flow plays an important role for one-dimesional loss modeling and design in radial turbine research. Tip leakage losses can be expressed as function of fluid momentum and mass flow passing through the tip gap ...

EFFECTS OF VARYING TIP CLEARANCE AND AXIAL GAP ON AXIAL-FLOW TURBINE STAGE PERFORMANCE ( PRESENT STATE OF THE ART) [PDF]
The Egyptian International Journal of Engineering Sciences and Technology, 2015 The leakage flow near the tip of rotor and stator blade rows of an axial-flow turbinestage imposes significant thermal loads on such blades. It is also responsible for theaerodynamic losses therein.

Advanced Materials, EarlyView.Elephant‐skin‐inspired crack networks are programmed in porous diatomaceous earth (DE)‐cement composites using substrate‐guided, stress‐concentration induced fracture. The resulting crack lattices act as capillary conduits that redistribute water, while the porous matrix stores moisture.
