Pressure Gradient Effects on Hypersonic Cavity Flow Heating
"... The effect of a pressure gradient on the local heating disturbance of rectangular cavities tested at hypersonic freestream conditions has been globally assessed using the twocolor phosphor thermography method. These experiments were conducted in the Langley 31Inch Mach 10 Tunnel and were initiated ..."

that the presence of the pressure gradient did not alter the open cavity heating for laminarentry/laminarexit flows, but did raise the average floor heating for closed cavities. The results of these riskreduction studies will be used to formulate a heating assessment of potential damage scenarios occurring
Influence of the nozzleexit boundarylayer thickness on the flow and acoustic fields of initially laminar jets
 15th AIAA/CEAS Aeroacoustics Conference, AIAA Paper
"... Round jets originating from a pipe nozzle are computed by LargeEddy Simulations (LES) to investigate the effects of the nozzleexit conditions on the flow and sound fields of initially laminar jets. The jets are at Mach number 0.9 and Reynolds number 105, and exhibit exit boundary layers characteri ..."

Strategies for Effectively Visualizing 3D Flow with Volume LIC
, 1997
"... This paper discusses strategies for effectively portraying 3D flow using volume line integral convolution. Issues include defining an appropriate input texture, clarifying the distinct identities and relative depths of the advected texture elements, and selectively highlighting regions of interest i ..."

;halos" that can help to intuitively indicate the presence of depth discontinuities between contiguous elements in a projection and thereby clarify the 3D spatial organization of elements in the flow. The proposed techniques are applied to the visualization of a hot, supersonic, laminar jet exiting into a colder

BRIEF NOTES Hydrodynamic Entry Length for Laminar Flow Between Parallel Porous Plates
"... with the value obtained from the slope in where a is a function of ionic diffusion coefficient, C 0 is the capacitance of the diffused layer at the point of zero charge, z is the valance, k is Boltzman's constant, e 0 is the electron charge, and T is the absolute temperature. This correction ..."
Flow Visualization ofRelaminarization Phenomena in Curved Pipes and the Related Measurements
"... Abstract: Flow visualization results for secondary flow phenomena at the exit of 90 " and 180 " bends and helically coiled pipes (1, 2 and 5 turns), (radius of curvature K = 381 mm, inside pipe diameter d=37.5 mm, curvature ratio dl2K = 0.049) and in the downstream straight pipe ( lid = 30 ..."
