Flow Characterization Of The Ul Smoke Box And Spot-Type Smoke Detectors, Christopher P. Menchini
Flow Characterization Of The Ul Smoke Box And Spot-Type Smoke Detectors, Christopher P. Menchini
Graduate Theses, Dissertations, and Problem Reports
The scope of this research involves the first known effort at designing a highly detailed computational fluid dynamics (CFD) model to characterize the flow fields with the UL Smoke Box and a spot type smoke detector within the test section of the smoke box. The proposed CFD model, designed to reflect the same measured conditions in the UL Smoke Box, was developed and validated through experimental velocity data using laser Doppler and hot-wire anemometry. With excellent qualitative comparisons between experimental and computational results, flow characterization using the laminar flow model available in the commercial software package FluentRTM was sufficiently achieved. …

Circulation Control For Download Wake Reduction On A Scaled V-22 Model, Chad Alan Riba
Graduate Theses, Dissertations, and Problem Reports
West Virginia University has developed a circulation controlled model of the V-22 wing to reduce the size of the download in the wake region brought upon by the airflow from the proprotors. The techniques being used in this experiment are the implementation of blowing slots across the leading edge and trailing edge, activation of one or both of the blowing devices, and adjustment of slot velocity. The results of the study show a decrease in the download force through the incorporation of the Coanda Effect around the leading and trailing edges. The induction of this phenomenon will move the separation …
