“…During the last several years, the code has been modified to permit the accurate prediction of many types of supersonic and h)rpersonic flows. The 3-D UPS code was extended to permit equilibrium and nonequilibrium airflow computations by TannehiU et al [34] and Buelow et al [35], respectively. Recently, the code has been enhanced to include internal flows with hydrogen-air chemistry [36], k -e turbulence modelling [37], finite-cataljrtic wall boundary conditions [38], and vibrational and elec tronic nonequilibrium effects [39].…”

“…The coupling between the fluids and chemistry can be enhanced through the implementation of Newton iterations on the governing equations at each streamwise step [30]. This loosely coupled approach for fluids and chemistry is pictorially depicted in Fig.…”

“…This eliminates the problem of determining the correct amount of smoothing which "plagued" many of the previous centrally-differenced PNS codes. The two-dimensional (2-D) [31] and three-dimensional (3-D) [32] versions of the UPS code have been extended to permit both equilibrium [22,28] and nonequilibrium [23,30] (finite-rate, chemically reacting) airflow computations. For nonequilibrium flows, the fluid dynamic and species continuity equations are solved in a loosely-coupled manner.…”

“…Numerous numerical methods have been proposed that either solve the unsteady Navier-Stokes (NS) equations [4][5][6][7][8][9][10][11][12][13][14] or the steady parabolized Navier-Stokes (PNS) equations [11,[15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30]. Typically the NS solvers require one to two orders-of-magnitude more computational time and storage as compared to the PNS solvers.…”

Thus, some thesis and dissertation copies are in typewriter face, while others may be from any type of computer printer.The quality of this reproduction is dependent upon the quality of the copy submitted. Broken or indistinct print, colored or poor quality illustrations and photographs, print bleedthrough, substandard margins, and improper alignment can adversely affect reproduction.In the unlikely event that the author did not send UMI a complete manuscript and there are missing pages, these will be noted. Also, if unauthorized copyright material had to be removed, a note wiU indicate the deletion.Oversize materials (e.g., maps, drawings, charts) are reproduced by sectioning the original, beginning at the upper left-hand comer and continuing from left to right in equal sections with small overlaps.
