This book was released on 1998 with total page 317 pages. Available in PDF, EPUB and Kindle. Book excerpt: CETTE RECHERCHE CONCERNE L'INTERACTION ENTRE UN JET PARIETAL SUPERSONIQUE ET UN ECOULEMENT TRANSVERSAL COMPRESSIBLE SUBSONIQUE, TELLE QU'ELLE APPARAIT POUR LE PILOTAGE EN FORCE DES MISSILES PAR JETS LATERAUX. L'OBJECTIF DE CETTE ETUDE EST DE CONTRIBUER A LA MODELISATION DES INTERACTIONS AERODYNAMIQUES COMPLEXES SE PRODUISANT AUTOUR DE LA TUYERE D'INJECTION (INTERACTIONS PROCHES) ET DANS LE PANACHE DU JET AU NIVEAU D'EVENTUELLES SURFACES AERODYNAMIQUES (INTERACTIONS LOINTAINES). L'EFFORT EST PORTE PLUS PARTICULIEREMENT SUR LES INTERACTIONS PROCHES. DEUX APPROCHES, L'UNE EXPERIMENTALE ET L'AUTRE NUMERIQUE, SONT MENEES EN PARALLELE. UNE CONFIGURATION FONDAMENTALE, CONSTITUEE PAR UN JET D'AIR FROID SUPERSONIQUE (M=2,5) DEBOUCHANT PERPENDICULAIREMENT D'UNE PAROI PLANE EST ETUDIEE DANS UNE SOUFFLERIE TRANSSONIQUE (M=0,8). DES VISUALISATIONS STRIOSCOPIQUES, PARIETALES ET TOMOGRAPHIQUES PAR PLAN LASER SONT COMPLETEES PAR DES MESURES DE PRESSIONS ET DE VITESSES MOYENNES EN PLEIN ECOULEMENT ET EN PAROI. UNE PREMIERE CARACTERISATION DES PHENOMENES INSTATIONNAIRES A GRANDE ECHELLE EST EFFECTUEE SUR LA BASE DE TOMOGRAPHIES ET D'ANALYSES SPECTRALES PAR FIL CHAUD. UN MODELE DECRIVANT L'INTERACTION EST PROPOSE. L'ETUDE NUMERIQUE CONSISTE A SIMULER L'ECOULEMENT A L'AIDE DE DEUX CODES DE CALCUL, L'UN RESOLVANT LES EQUATIONS D'EULER, L'AUTRE CELLES DE NAVIER-STOKES AVEC UN MODELE DE TURBULENCE A DEUX EQUATIONS DE TRANSPORT ET UNE LOI DE PAROI. AVEC CE DERNIER CODE, LE MAILLAGE EST RAFFINE AUTOUR DE L'ORIFICE ET DANS LE PANACHE GRACE A UNE PROCEDURE MULTIDOMAINE ET COMPORTE PLUS DE 700 000 POINTS. APRES AVOIR ETE VALIDES PAR COMPARAISON AVEC L'EXPERIENCE, LES RESULTATS NUMERIQUES SONT EXPLOITES POUR COMPLETER LE MODELE DES INTERACTIONS. CES SIMULATIONS NUMERIQUES PARTICIPENT EGALEMENT A L'ORIENTATION DES DEVELOPPEMENTS FUTURS DES CODES DE CALCUL ET DE LA RECHERCHE EXPERIMENTALE.

Download or read book Advances in Hydroinformatics written by Philippe Gourbesville and published by Springer. This book was released on 2015-08-21 with total page 616 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a collection of extended papers based on presentations given during the SIMHYDRO 2014 conference, held in Sophia Antipolis in June 2014. It focuses on the modeling and simulation of fast hydraulic transients, on 3D modeling, and on uncertainties and multiphase flows. The book explores both the limitations and performance of current models and presents the latest developments based on new numerical schemes, high-performance computing, multiphysics and multiscale methods, and better interaction with field or scale model data. It addresses the interests of practitioners, stakeholders, researchers and engineers active in this field.
Download or read book The Theory of Propellers written by Theodore Theodorsen and published by . This book was released on 1944 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: Summary: A technical method is given for calculating the axial interference velocity of a propeller. The method involves the use of certain weight functions P, Q, and F. Numerical values for the weight functions are given for two-blade, three-blade, and six-blade propellers.
Download or read book Solid Rocket Propulsion Technology written by A. Davenas and published by Newnes. This book was released on 2012-12-02 with total page 623 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book, a translation of the French title Technologie des Propergols Solides, offers otherwise unavailable information on the subject of solid propellants and their use in rocket propulsion. The fundamentals of rocket propulsion are developed in chapter one and detailed descriptions of concepts are covered in the following chapters. Specific design methods and the theoretical physics underlying them are presented, and finally the industrial production of the propellant itself is explained. The material used in the book has been collected from different countries, as the development of this field has occurred separately due to the classified nature of the subject. Thus the reader not only has an overall picture of solid rocket propulsion technology but a comprehensive view of its different developmental permutations worldwide.

Download or read book Hypersonic Flow Theory written by Wallace Hayes and published by Elsevier. This book was released on 2012-12-02 with total page 481 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hypersonic Flow Theory presents the fundamentals of fluid mechanics, focusing on the hypersonic flow theory and approaches in theoretical aerodynamics. This book discusses the assumptions underlying hypersonic flow theory, unified supersonic-hypersonic similitude, two-dimensional and axisymmetric bodies, and circular cylinder. The constant-streamtube-area approximation, streamtube-continuity methods, and tangent-wedge and tangent-cone are also deliberated. This text likewise covers the similar laminar boundary layer solutions, bluntness induced interactions on slender bodies, and free molecule transfer theory. The dynamics of hypersonic flight or hypersonic wing theory, magnetohydrodynamic theory, or any developments involving treatment of the Boltzmann equation are not included. This publication is intended for hypersonic aerodynamicists, students, and researchers conducting work on the hypersonic flow phenomena.

Book excerpt: Chaos theory is giving scientists fresh insights into all sorts of unruly phenomena-from dripping faucets to swinging pendulums, from the vagaries of the weather to the movements of the planets, from heart rhythms to gold futures. In this collection of front-line reports, edited for the general reader, internationally recognized experts such as Ian Stewart, Robert M. May, and Benoit Mandelbrot draw on the latest research to trace the roots of chaos in modern science and mathematics.
