Book Synopsis Three Dimensional Hydrodynamic Calculations with Adaptive Mesh Refinement of the Evolution of Rayleigh Taylor and Richtmyer Meshkov Instabilities in Converging Geometry by :
Download or read book Three Dimensional Hydrodynamic Calculations with Adaptive Mesh Refinement of the Evolution of Rayleigh Taylor and Richtmyer Meshkov Instabilities in Converging Geometry written by . This book was released on 1993. Available in PDF, EPUB and Kindle. Book excerpt: The authors present results for high resolution hydrodynamic calculations of the growth and development of instabilities in shock driven imploding spherical geometries in both 2D and 3D. They solve the Eulerian equations of hydrodynamics with a high order Godunov approach using local adaptive mesh refinement to study the temporal and spatial development of the turbulent mixing layer resulting from both Richtmyer Meshkov and Rayleigh Taylor instabilities. The use of a high resolution Eulerian discretization with adaptive mesh refinement permits them to study the detailed three-dimensional growth of multi-mode perturbations far into the non-linear regime for converging geometries. They discuss convergence properties of the simulations by calculating global properties of the flow. They discuss the time evolution of the turbulent mixing layer and compare its development to a simple theory for a turbulent mix model in spherical geometry based on Plesset's equation. Their 3D calculations show that the constant found in the planar incompressible experiments of Read and Young's may not be universal for converging compressible flow. They show the 3D time trace of transitional onset to a mixing state using the temporal evolution of volume rendered imaging. Their preliminary results suggest that the turbulent mixing layer loses memory of its initial perturbations for classical Richtmyer Meshkov and Rayleigh Taylor instabilities in spherically imploding shells. They discuss the time evolution of mixed volume fraction and the role of vorticity in converging 3D flows in enhancing the growth of a turbulent mixing layer.

Book Synopsis Transonic Flow Calculations in Two- and Three-Dimensions by :
Download or read book Transonic Flow Calculations in Two- and Three-Dimensions written by . This book was released on 1973. Available in PDF, EPUB and Kindle. Book excerpt: In recent years attempts to improve the performance of nozzle, rotors, compressors, airfoil sections, wings, and airplanes have revived research efforts in transonic aerodynamics. The present investigation describes various aspects of transonic flow calculations by a relaxation method. Of primary interest are techniques to reduce computational times for three-dimensional flows. Solutions of the small disturbance and full three-dimensional potential flow equations are obtained for two- and three-dimensional geometries. Several different geometries are considered.
