Transonic and supersonic Euler computations of vortex-dominated flow fields about a generic fighter

Flow fields about a generic flighter model were computed using FL057, a 3-D, finite volume Euler code. Computed pressure coefficients, forces, and moments at several Mach numbers (0.6, 0.8, 1.2, 1.4, and 1.6) are compared with wind tunnel data over a wide range of angles of attack in order to determine the applicability of the code for the analysis of fighter configurations. Two configurations were studied, a wing-body and a wing-body-chine. FL057 predicted pressure distributions, forces, and moments well at low angles of attack, at which the flow was fully attached. The FL057 predictions were also accurate for some test conditions once the leading edge vortex became well established. At the subsonic speeds, FL057 predicted vortex breakdown earlier than that seen in the experimental results. Placing the chine on the forebody delayed the onset of bursting and improved the correlation between numerical and experimental data at the subsonic conditions

Evaluation of HCFC AK 225 Alternatives for Precision Cleaning and Verification

Maintaining qualified cleaning and verification processes are essential in an production environment. Environmental regulations have and are continuing to impact cleaning and verification processing in component and large structures, both at the Michoud Assembly Facility and component suppliers. The goal of the effort was to assure that the cleaning and verification proceeds unimpeded and that qualified, environmentally compliant material and process replacements are implemented and perform to specifications. The approach consisted of (1) selection of a Supersonic Gas-Liquid Cleaning System; (2) selection and evaluation of three cleaning and verification solvents as candidate alternatives to HCFC 225 (Vertrel 423 (HCFC), Vertrel MCA (HFC/1,2-Dichloroethylene), and HFE 7100DE (HFE/1,2 Dichloroethylene)); and evaluation of an analytical instrumental post cleaning verification technique.

Emerging Adults' Views on Masspersonal Self-Disclosure and their Bridging Social Capital on Facebook

Masspersonal self-disclosure on social network sites entails new risks and benefits for bridging social capital, defined as social resources such as a connection to and investment in large and heterogeneous collectives, which are important to develop during the transition to adulthood in democratic societies. To better understand motivations and social capital consequences of masspersonal self-disclosure among emerging adults, this mixed-method study examined how U.S. college students view various topics of masspersonal self-disclosure and whether values embedded in their views contributed to their perceived bridging social capital, after accounting for their Facebook use and the diversity of their networks. A total of 208 (110 women, 95 men, 3 non-binary, Mage = 20.28) students completed online questionnaires while referring to their Facebook profiles. Qualitative analyses showed how valuing self-expression, alongside other-focused values, informed participants’ decision-making about masspersonal self-disclosure. Quantitative results showed that valuing self-expression more frequently across topics of self-disclosure predicted bridging social capital; however, the use of Facebook privacy controls and indicators of ethnic and political diversity in students’ networks did not. We discuss the importance of values in understanding emerging adults’ behaviors on social network sites, their generation of bridging social capital, and civic identity development
