Environmental Policy and Governance, Volume 36, Issue 2, Page 330-342, April 2026.ABSTRACT The implementation of effective climate governance increasingly relies on advisory bodies that monitor the effectiveness of policies and management mechanisms. Despite their strategic importance to institutionalizing climate governance, limited attention has been paid to the roles, trajectories, and effectiveness of these advisory bodies ...

Effect of tip winglet angle on internal complex flow and aerodynamic performance of an axial fan [PDF]
International Journal of Fluid EngineeringThe effects of winglet angle on the flow characteristics in the tip clearance region of the AXF950 axial fan are studied in depth by numerical and experimental methods at different winglet angles (0°, 15°, 30°, 45°, 60°, and 90°).

Segmented Gurney Flaps for Improved Wind Turbine Wake Recovery
Wind Energy, Volume 29, Issue 3, March 2026.ABSTRACT When wind passes through the rotor of a wind turbine, the velocity is decreased while turbulence is increased. The region of decreased wind speed behind the rotor is known as the wind turbine wake and is bounded by a complex structure of helical vortices. This structure occurs to be more stable in low ambient turbulence and low tip speed ratio

Optimization in Conceptual Design of a BWB UAV Using an Adaptive Kriging‐Based Surrogate Model
Engineering Reports, Volume 8, Issue 2, February 2026.An adaptive Kriging‐based framework for Blended Wing Body UAV optimization is presented. The exploitation‐oriented strategy yields a 14.5% range improvement, while sensitivity analysis identifies fuel mass as the dominant parameter for efficient conceptual design. ABSTRACT To improve optimization efficiency in the conceptual design of Blended Wing Body

Asia-Pacific Journal of Chemical Engineering, Volume 21, Issue 1, January/February 2026.ABSTRACT Proton exchange membrane fuel cells (PEMFC) are regarded as the best clean energy conversion technology because of their smaller number of emissions and higher efficiency. This numerical investigation used two different flow channel designs—the serpentine flow field (SFF) and the lung serpentine flow field (LSFF)—with active areas of 5 by 5 cm.
