INTERACTION AVEC LA PROPAGATION D'UNE FLAMME ALLUMEE PAR ETINCELLE written by Alain Floch and published by . This book was released on 1990 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: CE MEMOIRE CONCERNE L'ETUDE DE L'INTERACTION DE LA TURBULENCE AVEC LA PROPAGATION D'UNE FLAMME DANS UNE CAVITE FERMEE. LA TURBULENCE INITIALE A ETE GENEREE GRACE A UN SYSTEME DE PISTON-BLOCS PERFORES. DES MESURES DE VITESSE PAR VELOCIMETRIE DOPPLER LASER EN UN POINT, PUIS EN DEUX POINTS, ONT ETE REALISEES POUR LA DETERMINATION DE L'ENERGIE ET DES ECHELLES TEMPORELLES ET SPATIALES DE LA TURBULENCE. L'ETUDE A D'ABORD ETE MENEE EN L'ABSENCE DE COMBUSTION, PUIS EN PRESENCE DE LA PROPAGATION D'UNE FLAMME DE PROPANE-AIR. IL EST MONTRE QUE LES PHENOMENES ETUDIES SONT SIMILAIRES A CEUX RENCONTRES DANS LES MOTEURS; LA REALISATION DES MESURES ETANT CEPENDANT FACILITEE PAR DE LARGES ACCES OPTIQUES. LA GENERATION D'UNE TURBULENCE D'INTENSITE ET D'ECHELLES VARIABLES A PERMIS L'OBTENTION D'UN LARGE EVENTAIL DE CARACTERISTIQUES DE FLAMMES LENTES ET RAPIDES, QUI ONT ETE ETUDIEES STATISTIQUEMENT. LA PRESENCE DES FLUCTUATIONS CYCLIQUES DE VITESSE DANS L'ECOULEMENT A DONNE LIEU A UNE ETUDE DE L'INFLUENCE DES MOYENNES STATISTIQUES D'ENSEMBLE ET DE CYCLE RESOLU SUR L'ENERGIE ET LES ECHELLES DE LA TURBULENCE. LES MESURES CONDITIONNELLES DE VITESSE DANS LES GAZ FRAIS ONT PERMIS D'ACCEDER A LA VITESSE DE COMBUSTION TURBULENTE

This book was released on 1997 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: CETTE ETUDE CONSISTE EN L'ELABORATION D'UN MODELE NUMERIQUE DE PREDICTION DU BRUIT DE COMBUSTION. LE NIVEAU GLOBAL AINSI QUE LA DISTRIBUTION SPECTRALE DE PUISSANCE ACOUSTIQUE RAYONNEE PAR UNE FLAMME TURBULENTE SONT DEFINIS. LES FLUCTUATIONS LOCALES DE MASSE VOLUMIQUE SONT EXPRIMEES A PARTIR D'UNE COMBINAISON DES EQUATIONS DE L'AEROTHERMOCHIMIE ET DE LA MECANIQUE DES FLUIDES. SUIVANT UNE APPROCHE SIMILAIRE A CELLE EMPLOYEE PAR LIGHTHILL, LES TERMES SOURCES ACOUSTIQUES DU BRUIT DE COMBUSTION SONT IDENTIFIES. LE DEGAGEMENT INSTATIONNAIRE DE CHALEUR LOCAL CONSTITUE LA PRINCIPALE ORIGINE DU BRUIT EMIS PAR UNE FLAMME TURBULENTE A FAIBLE NOMBRE DE MACH. CE DEGAGEMENT CALORIFIQUE EST ECRIT EN FONCTION DES FLUCTUATIONS DE TEMPERATURE. A PARTIR D'UNE APPROCHE STATISTIQUE, UNE EXPRESSION DU SPECTRE DE PUISSANCE ACOUSTIQUE EST ETABLIE. ELLE MET EN JEU L'AMPLITUDE DES TERMES SOURCES SONORES ET UNE FONCTION DE COHERENCE SPATIO-FREQUENTIELLE RENDANT COMPTE DE L'INFLUENCE DE LA STRUCTURE DE LA FLAMME SUR SON EMISSION ACOUSTIQUE. L'ORGANISATION SPATIO-FREQUENTIELLE DES TERMES DE PRODUCTION ACOUSTIQUE EST DETERMINEE SUR LA BASE D'INVESTIGATIONS EXPERIMENTALES. LA FLAMME TURBULENTE ETUDIEE APPARTIENT A LA CLASSE DES FLAMMES JET ET VERIFIE L'HYPOTHESE DE TAYLOR. LES DENSITES SPECTRALES DES TERMES SOURCES SONT EXAMINEES ET UN TEMPS CARACTERISTIQUE DES FLUCTUATIONS DE TEMPERATURE EST IDENTIFIE. PAR LA SUITE ET SUR LA BASE DES RESULTATS EXPERIMENTAUX OBTENUS, UNE EXPRESSION DE LA FONCTION DE COHERENCE SPATIO-FREQUENTIELLE EST PROPOSEE. CETTE FORMULATION INTRODUIT UNE FONCTION SPATIALE QUI DEFINIT UN VOLUME SOURCE COHERENT ET UNE FONCTION FREQUENTIELLE PERMETTANT DE REPRESENTER LA COMPETITION ENTRE LA TURBULENCE ET LA COMBUSTION. UNE ETUDE NUMERIQUE EST ENSUITE ENGAGEE. ON ESTIME TOUT D'ABORD LES GRANDEURS NECESSAIRES AU CALCUL ACOUSTIQUE VIA UN CODE DE CALCUL INTEGRANT UN MODELE DE TURBULENCE DE TYPE K-EPSILON COUPLE A UN MODELE DE COMBUSTION DE TYPE SCALAIRE CONSERVE A DENSITE DE PROBABILITE PRESUMEE. LES SPECTRES DE PUISSANCE ACOUSTIQUE NUMERIQUES SONT ALORS CONFRONTES AUX RESULTATS EXPERIMENTAUX. LES TENDANCES OBSERVEES DANS LA PRATIQUE SONT VERIFIEES PAR LE MODELE AEROTHERMOACOUSTIQUE. ON MONTRE AINSI QUE LA PREDICTION DU BRUIT DE COMBUSTION A PARTIR DE CHAMPS THERMODYNAMIQUES NUMERIQUES EST POSSIBLE
