High effectiveness tip cooling using inclined slots
The tip of the High-Pressure Turbine (HPT) blade is critical for gas turbine performance. Hot gas leaking through the tip gap tends to oxidize and erode the blade, while generating significant aerodynamic loss.

Active cool roof effect: impact of cool roofs on cooling system efficiency
Advances in Building Energy Research, 2013 Cool roofs represent an acknowledged, relatively simple, and low-cost strategy to reduce cooling energy demand of buildings and mitigate urban heat island phenomena. The purpose of this paper is to study the coupled passive–active effect produced by such a technology, where the active effect consists of the cool roof capability to decrease the suction ...

Advanced Engineering Materials, EarlyView.This study demonstrates an efficient recycling route for out‐of‐spec AlSi10Mg atomized powders through compaction and arc remelting followed by suction casting. By correlating compaction load, cooling rate, and resulting microstructure, we show that intermediate pressures (50–80 kN) and rapid cooling refine dendrites, reduce porosity, and enhance ...
