RISExperimental Investigation of In-Hole Evolutionary Flow Behavior in a 777-Shaped Jet in Crossflow Via Refractive Index Matching-Based TR-PIV Technique
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. The 777-shaped jet in crossflow (JICF) has been widely used in film cooling applications. To elucidate in-hole flow behavior and its evolution, time-resolved particle image velocimetry and refractive index matching ...
Enhanced Antideposition Performance of Film Cooling With a Shaped Sweeping Jet Hole
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Shaped sweeping jet (SSJ) holes represent an advancement in sweeping jet (SJ) technology, as they offer enhanced cooling performance. To reveal the antideposition capabilities of SSJs, particle deposition results of ...
Film Cooling Performances Under Various Upstream Roughness Conditions: Experimental Investigations and Similarity Hypothesis
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Roughness caused by deposition, erosion, and additive manufacturing can significantly affect gas turbine efficiency. Previous research has often examined film cooling performance under limited roughness configurations, ...
