(author), Kennicutt, R. C. (author), Kreckel, K. (author), Rigopoulou, D. (author), van der werf, p (author), Wilson, C (author)The [C ii] 158 μm fine-structure line is the brightest emission line observed in local star-forming galaxies. As a major coolant of the gas-phase interstellar medium, [C ii] balances the heating, including that due to far-ultraviolet photons, which heat the gas via the photoelectric effect. However, the origin of [C ii] emission remains...journal article 2017

G.G.M. (author)With its relatively low ionization potential, C<sup>+</sup> can be found throughout the interstellar medium (ISM) and provides one of the main cooling channels of the ISM via the [C ii] 157 μm emission. While the strength of the [C ii] line correlates with the star formation rate, the contributions of the various gas phases to the [C ii]...journal article 2017

(author), Galametz, Maud (author), Groves, Brent (author), Helou, George (author), Herrera-Camus, Rodrigo (author), Hunt, Leslie (author), Kennicutt, Robert (author), Walter, Fabian (author), Wolfire, Mark (author)We present [C ii] 158 μm measurements from over 15,000 resolved regions within 54 nearby galaxies of the Kingfish program to investigate the so-called [C ii] "line-cooling deficit" long known to occur in galaxies with different luminosities. The [C ii]/TIR ratio ranges from above 1% to below 0.1% in the sample, with a mean value of 0.48 ± 0...journal article 2017

(author), Boquien, Mederic (author), Tabatabaei, F. S. (author), Beirão, Pedro (author)The [NII] 122 and 205 um transitions are powerful tracers of the ionized gas in the ISM: (1) the [NII] 122/205 line ratio can be used to measure the electron density of the low-excitation, ionized gas, and (2) the intensity of these lines is directly related to the flux of ionizing photons, probing the most recent star formation activity. The...journal article 2016

Anderson, M.E. (author), McKee Smith, J. (author), McKay, S.K. (author)Flooding resulting from hurricanes and other extreme storm events is a prominent risk along the coasts. These coastal areas are typically of low elevation and relief,making land and infrastructure highly susceptible to inundation by storm surge and waves. These verity of this threat is exacerbated by sea level rise and a possible increase in...report 2011

Labrujère, T.E. (author), Maarsingh, R.A. (author), Smith, J. (author)Measurements on a simple aircraft model in both an appropriately sized and a relatively large, low-speed, solid-wall test section were used to analyse the accuracy and consistency of measured-boundary-condition (MBC) methods. For completeness, the classical method of images, with two different correction procedures, was also analysed. For the...report 1988

Smith, J. (author)The displacement effect of a body in an air stream increases when regions of non-linear flow, such as locally supersonic flow, occur. Therefore, a subsonic formulation of the displacement effect must fail for transonic flow conditions. It is shown that, for the particular case of a two-dimensional aerofoil, a subsonic formulation may...report 1986

Smith, J. (author)The applicability of a multi-velocity-component static pipe, proposed by CALSPAN ATC, for measuring boundary velocity vector distributions in behalf of wall interference assessment, has been explored in two-dimensional flow. Comparisons with alternative methods to derive the local flow angle from measured pipe pressures as well as analyses of...report 1985

Maarsingh, R.A. (author), Labrujère, T.E. (author), Smith, J. (author)The present paper describes two alternative correction methods for wall interference based on measured boundary conditions. In both methods it is assipied that at or near the tunnel boundary the flow velocity will be measured in magnitude and direction and that the main part of the flow field may be considered irrotational and subsonic. One...report 1984

Smith, J. (author)The applicability of two-dimensional flexible solid wall test sections for three-dimensional testing is theoretically investigated for linearized subsonic flow. The method uses known interference velocity distributions along a targer line (derived from a method of images for this particular study). From these, wall shapes are calculated that...report 1984

Smith, J. (author)Modern developments in wind tunnel wall correction methods are for a major part directed towards the use of in situ measured boundary conditions in order to eliminate the need to describe the complicated aerodynamic characteristics of test section walls. This paper presents a short general review of the principles of such methods for 2D flow....report 1982

Smith, J. (author)A "measured-boundary-condition" method for determining 2D wall interference has been developed. It applies measured "wall" pressure distributions and a model representation to determine the 2D interference flow field associated with the presence of the test section walls. Special attention has been paid to the model representation. The...report 1981

Smith, J. (author)The report describes experiences with the Garabedian and Korn program for the computation of compressible potential flows, with or without shocks, both supercritical shockless flows and flows with shock waves. Computations for a number of quasi-elliptical aerofoils indicated that the conformal mapping procedure should be handled with care....report 1974
