Abstract The principal objectives of this research are to investigate the distribution of fish larvae in relation to environmental factors in Chiku lagoon and the coastal waters of Tainan, Southwestern Taiwan during the period from August 1998 to June 1999 and during August 13~14, 1997. Seventy-six species of the fish larvae belonging to 65 genera were identified in Chiku lagoon and the mean numerical abundance of the fish larvae was 29 ¡Ó44 inds./100m3 during the sampling period between August 1998 and June 1999; and the dominant species were Omobranchus fasciolaticeps¡BGobiidae gen. sp.¡BSillago maculata and Engraulis japonica. Seventy-two species of the fish larvae belonging to 66 genera were identified in the coastal waters off Chiku lagoon during two cruises of December 1998 and June 1999, with the mean numerical abundance of 35 ¡Ó24 inds./100m3 ; and the dominant species were Myctophidae gen. sp., Ceratoscopelus warming, S. maculata and E. japonica. Eighty-three species of fish larvae belonging to 73 genera were identified and the mean numerical abundance was 35 ¡Ó49 inds./100m3 during the cruise of August 13~14, 1997 at 6 stations along a transect from the coastal waters near Tsengwen River to the waters south of Penghu Island, and the dominant species were Bothidae gen. sp., Stomioidae gen. sp. and Mullidae gen. sp.. The abundance, species number and species diversity of fish larvae were usually higher in the coastal waters of Tainan than in Chiku lagoon. The larval fish assemblages of Chiku lagoon was significantly different from that of the coastal waters of Tainan. The dominant species of fish larvae in the coastal water of Tainan were mostly meso-epipelagic species¡]Myctophidae, C. warningi, Diaphus sp., and Carangidae¡^, while Chiku lagoon was dominated by sandy benthic species¡]Blenniidae¡^and estuarine species ¡]Gobiidae and Engraulidae¡^. The species number and abundance of fish larvae in the coastal water of Tainan were found higher in wet season¡]June¡^than in dry season¡]December¡^. The abundance of fish larvae was significantly different among stations and seasons, but did not different between tides in Chiku lagoon. The abundance of fish larvae was higher at night than during the day in August, 1998 and was usually higher in spring ¡]April¡^and lower at the middle station of Chiku lagoon. The abundance of fish larvae was not significantly correlated with water temperature and salinity, but higher abundance of fish larvae was always found when temperature was between 26¢Jand 30¢J, and in higher salinity ¡]34‰ ~36‰¡^. In the transect study, the abundance of fish larvae was significantly different between surface and deep tows¡]p<0.05¡^, but not among stations and between day and night (p>0.05).

California Polytechnic State University, San Luis Obispo is currently working towards developing a Computational Fluid Dynamics (CFD) database for future code validation efforts. Cal Poly will complete a wind tunnel test on the Advanced Model for Extreme Lift and Improved Aeroacoustics (AMELIA) in the National Full-Scale Aerodynamics Complex (NFAC) 40 foot by 80 foot wind tunnel at NASA Ames Research Center in the summer of 2011. The development of two measurement techniques is discussed in this work, both with the objective of making measurements on AMELIA for CFD validation. First, the work on the application of the Fringe-Imaging Skin Friction (FISF) technique to AMELIA is discussed. The FISF technique measures the skin friction magnitude and direction by applying oil droplets on a surface, exposing them to flow, measuring their thickness, and correlating their thickness to the local skin friction. The technique has the unique ability to obtain global skin friction measurements. A two foot, nickel plated, blended wing section test article has been manufactured specifically for FISF. The model is illuminated with mercury vapor lamps and imaged with a Canon 50D with a 546 nm bandpass filter. Various tests are applied to the wing in order to further characterize uncertainties related with the FISF technique. Human repeatability has uncertainties of ±2.3% of fringe spacing and ±2.0° in skin friction vector direction, while image post processing yields ±25% variation in skin friction coefficient. A method for measuring photogrammetry uncertainty is developed. The effect of filter variation and test repeatability was found to be negligible. A validation against a Preston tube was found to have 1.8% accuracy. Second, the validation of a micro flow measurement device is investigated. Anemometers have always had limited capability in making near wall measurements, driving the design of new devices capable of measurements with increased wall proximity. Utilizing a thermocouple boundary layer rake, wall measurements within 0.0025 inches of the surface have been made. A Cross Correlation Rake (CCR) has the advantage of not requiring calibration but obtaining the same proximity and resolution as the thermocouple boundary layer rake. The flow device utilizes time of flight measurements computed via cross correlation to calculate wall velocity profiles. The CCR was designed to be applied to AMELIA to measure flow velocities above a flap in a transonic flow regime. The validation of the CCR was unsuccessful. Due to the fragile construction of the CCR, only one data point at 0.10589 inches from the surface was available for validation. The subsonic wind tunnel’s variable frequency drive generated noise which could not be filtered or shielded, requiring the use of a flow bench for validation testing. Since velocity measurements could not be made in the flow bench, a comparison of a fast and slow velocity was made. The CCR was not able to detect the difference between the two flow velocities. Currently, the CCR cannot be applied on AMELIA due to the unsuccessfully validation of the device.
