Book excerpt: A method of solving the three-dimensional, incompressible turbulent boundary-layer equations was developed using a Crank-Nicholson implicit finite-difference technique, with the turbulent stress terms modeled with an eddy-viscosity model obtained from mixing length theory. The method was applied to two three-dimensional flow geometries for which experimental data exists and a comparison with this data showed excellent agreement. A complete computer program was sufficiently generalized for application to two-dimensional laminar and turbulent flows with arbitrary pressure gradients. The method was applied to several such test cases and the solutions agreed well with both theory and experiment. An analysis was presented to determine the conditions for which the finite difference equations were stable and convergent. (Author).

Download or read book Analysis of the Three-dimensional Compressible Turbulent Boundary Layer on a Sharp Cone at Incidence in Supersonic and Hypersonic Flow written by John C. Adams and published by . This book was released on 1972 with total page 98 pages. Available in PDF, EPUB and Kindle. Book excerpt: An analytical approach toward numerical calculation of the three-dimensional turbulent boundary layer on a sharp cone at incidence under supersonic and hypersonic flow conditions is presented. The theoretical model is based on implicit finite-difference integration of the governing three-dimensional turbulent boundary-layer equations in conjunction with a three-dimensional scalar eddy-viscosity model of turbulence. Comparison is made of present theory with detailed experimental measurements of the three-dimensional turbulent boundary-layer structure (velocity and temperature profiles), the surface streamline direction (obtained via an oil-flow technique) and surface heat-transfer rate.

Available in PDF, EPUB and Kindle. Book excerpt: An implicit finite difference technique, in curvilin ear-orthogonal surface coordinates, has been developed for the solution of the differential equations of three-dimensional laminar and turbulent boundary layers on ship forms. For turbulent flow, a two-layer eddy-viscosity model has been employed as the closure model. The initial and boundary conditions required to solve the equations and the stability and accuracy of the numerical method are discussed at some length. Two mathematically-defined simple three-dimensional ship forms are studied in some detail. These are a tri-axial ellipsoid and a double elliptic ship.

Available in PDF, EPUB and Kindle. Book excerpt: Three-dimensional, incompressible, laminar boundary layer over a spinning blunt body of revolution at incidence and the associated Magnus forces are investigated. Complete solutions for two different, moderate and high, spin rates are obtained by an implicit finite-difference method. A great variety of the circumferential-velocity profiles are determined. Magnus force contributed from the circumferential skin friction and the centrifugal pressure are calculated. These two side-forces partly compensate each other. At lower spin rate, the friction force is larger resulting in a positive Magnus force. At higher spin rate, the opposite is obtained. The changes of the Magnus force from positive at lower spin rate to negative at higher spin rate was previously observed experimentally.

Available in PDF, EPUB and Kindle. Book excerpt: The problem of choosing orthogonal, curvilinear, coordinate systems for use in boundary-layer calculations on arbitrary three-dimensional bodies is considered in some detail. A general method for the practical evaluation of the various geometrical properties of the coordinates occurring in the three-dimensional boundary-layer equations is described. A particular coordinate system which appears to be the most convenient one for ship hulls is then proposed and analyzed further.

Book Synopsis Three-dimensional Turbulent Boundary Layer on a Spinning Cone at Angle of Attack by : C. Phillip Ford III
Download or read book Three-dimensional Turbulent Boundary Layer on a Spinning Cone at Angle of Attack written by C. Phillip Ford III and published by . This book was released on 1978 with total page 121 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report investigates the three-dimensional turbulent boundary layer on a spinning cone at small angles of attack in incompressible flow. It is assumed that the boundary layer has no effect on the inviscid flow and thus the inviscid flow is used as the outer boundary condition for the boundary layer equations. A momentum integral technique was used to reduce the governing equations to two. The two resulting partial differential equations were then solved by an implicit finite-difference technique of the marching type. The numerical method developed here gives results which follow the trend of available experimental data and other analytical results. This method was also found to be stable and accurate and fairly insensitive to the step size used in the finite-difference method. Computer solution could be found in the cases where spin rate produces surface velocity at the base of the cone less than the free stream velocity. Test cases were run with a free stream velocity of 60.96 meters per second with a cone half angle of 10 degrees. Angle of attack was either zero or five degrees with spin rates of 0, 400, and 500 revolutions per minute. Typical execution times was less than three minutes on an IBM 370/165 computer. (Author).
