Abstract:
A 1:17 scale model of a notional rotor hub of a large helicopter was tested in the Pennsylvania State University (PSU) Applied Research Laboratory (ARL) 12-inch test section water tunnel. Objectives of the experiment were to quantify effects of Reynolds number, advance ratio, and hub geometry configuration on the drag and shed wake of the rotor hub. A range of flow conditions were tested, with hub diameter-based Reynolds numbers ranging from 1.06×10⁵ to 2.62×10⁶ and advance ratios ranging from 0.2 to 0.4, as well as non-rotating cases. Three hub geometry configurations were tested with various

Abstract:
Abstract Crack advance has been studied in a X-70 pipeline steel, using the compliance technique. The electrolyte was very dilute brine bubbled with 10% carbon dioxide. Cracking rates were studied at a range of frequencies and R-values. The R-values simulated typical high-pressure gas service, but the frequency used was significantly higher. Similar testing was carried out in the presence of a 1% hydrogen sulfide using the Shell Canada sour gas test facility. The crack advance observed in dilute brine bubbled with 10% carbon dioxide could be explained using the rates of corrosion fatigue and a

Abstract:
Abstract Hydrothermal liquefaction (HTL) of wet and waste biomass feedstocks into crude bio-oils and other chemicals has attracted particular attention in Canadian and international clean energy sectors. Until today, very little effort has been employed to address corrosion problems of HTL core components under operation, leading to a significant delay in the construction of industrial-scale HTL plants. In fact, a range of oxygenated, aggressive sulfur and/or chlorinated compounds, as well as organic acids, can be introduced during the conversion at the operating temperature range of 200–400°C

Abstract:
A low-Reynolds number rectilinear analog of the retreating blade problem is considered by computationally and experimentally studying a NACA0012 blade in spanwise oscillation in a free stream. Three-dimensional hybrid RANS-LES simulations with spanwise periodic boundary conditions and experimental flow visualization support the description of experimental direct force measurements for a wide range reduced frequencies and advance ratios, including fully reversed flow conditions. A fixed incidence of 6 degrees is taken as a nominally attached-flow case, and agrees reasonably well with Isaacs' th

The present study considers a compound helicopter with an articulated main rotor and uses a physics-based approach to arrive at, and understand, the optimal trim states at high-speeds in the 225-250 kts range. Simulations are based on a compound derivative of a modified UH-60A helicopter with a 20,110 lbs gross weight operating at sea level. The study shows that it is critical to use ailerons on the wing to counteract the propulsor torque and reduce rotor lateral cyclic pitch requirement and lateral cyclic flapping. Also, the stabilator needs to be used to fly the aircraft at a nose-level pitc

Fatigue crack growth rate increased with decreasing frequency and reached a plateau value at low frequencies. The observed behavior is typical for hydrogen enhanced cracking in sour environment.

With moderate or light winds and a clear sky the diurnal heating which occurs near the sea surface can cause a serious reduction in the range of submarine detection, especially on shallow targets. This has usually been called the “afternoon effect", although as will be noticed below the ranges often remain short long after sun down. The heating of surface waters which causes such sharp downward refraction can of course be noted on a bathythermograph record, provided pen vibration does not confuse the upper part of the trace.
