Harris and published by . This book was released on 1971 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: A numerical method for solving the equations for laminar, transitional, and turbulent compressible boundary layers for either planar or axisymmetric flows is presented. The fully developed turbulent region is treated by replacing the Reynolds stress terms with an eddy viscosity model. The mean properties of the transitional boundary layer are calculated by multiplying the eddy viscosity by an intermittency function based on the statistical production and growth of the turbulent spots. A specifiable turbulent Prandtl number relates the turbulent flux of heat to the eddy viscosity. A three-point implicit finite-difference scheme is used to solve the system of equations. The momentum and energy equations are solved simultaneously without iteration. Numerous test cases are compared with experimental data for supersonic and hypersonic flows; these cases include flows with both favorable and mildly unfavorable pressure gradient histories, mass flux at the wall, and traverse curvature.

This book was released on 1961 with total page 1 pages. Available in PDF, EPUB and Kindle. Book excerpt: A finite-difference technique is developed for analyzing the time-dependent two-dimensional flow of an incompressible viscous fluid over a semi-infinite flat plate. The complete (nonlinear) equations of motion for perturbed Blasius flow are numerically integrated with respect to time, and the propagation of disturbances in the boundary layer is determined. An analysis of the theoretical convergence and stability properties of the difference scheme is carried out. The method developed has been employed in two test calculations, in which slightly unstable oscillatory disturbances have been introduced at some upstream point. The numerical solutions exhibit many of the major theoretical and experimentally observed features associated with transition from laminar to turbulent boundary-layer flow. (Author).

This book was released on 2018-05-30 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: In order to expand the predictive capability of single-point turbulence closure models to account for the early-stage transition regime, a methodology for the formulation and calibration of model equations for the ensemble-averaged disturbance kinetic energy and energy dissipation rate is presented. First the decay of laminar disturbances and turbulence in mean shear-free flows is studied. In laminar flows, such disturbances are linear superpositions of modes governed by the Orr-Sommerfeld equation. In turbulent flows, disturbances are described through transport equations for representative mean quantities. The link between a description based on a deterministic evolution equation and a probability based mean transport equation is established. Because an uncertainty in initial conditions exists in the laminar as well as the turbulent regime, a probability distribution must be defined even in the laminar case. Using this probability distribution, it is shown that the exponential decay of the linear modes in the laminar regime can be related to a power law decay of both the (ensemble) mean disturbance kinetic energy and the dissipation rate. The evolution of these mean disturbance quantities is then described by transport equations similar to those for the corresponding turbulent decaying flow. Second, homogeneous shear flow, where disturbances can be described by rapid distortion theory (RDT), is studied. The relationship between RDT and linear stability theory is exploited in order to obtain a closed set of modeled equations. The linear disturbance equations are solved directly so that the numerical simulation yields a database from which the closure coefficients in the ensemble-averaged disturbance equations can be determined.Grosch, Chester E.Langley Research CenterPERTURBATION THEORY; DISTORTION; TRANSITION FLOW; TURBULENT FLOW; CLOSURE LAW; LAMINAR FLOW; SHEAR FLOW; ORR-SOMMERFELD EQUATIONS; ENERGY DISSIPATION; KINETIC ENERGY; LINEAR EQUATIONS; MATHEMATICAL MOD

This book was released on 2018-08-13 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: A vectorized, semi-implicit code was developed for the solution of the time-dependent, three dimensional equations of motion in plane Poiseuille flow by the large-eddy simulation technique. The code is tested by comparing results with those obtained from the solutions of the Orr-Sommerfeld equation. Comparisons indicate that finite-differences employed along the cross-stream direction act as an implicit filter. This removes the necessity of explicit filtering along this direction (where a nonhomogeneous mesh is used) for the simulation of laminar flow transition into turbulence in which small scale turbulence will be accounted for by a subgrid scale turbulence model.
