  3. 2. Parametric stability analyses for fluid-loaded thin membranes

    Författare :Yang Zhou; Anders Eriksson; Håkan Johansson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Membranes; Hydro-static load; Multi-parametric loading; Bifurcations; Generalized path-following; Fold lines; Mesh eects; Augmenting equations; Generalized eigenproblem; Solution surface.; Engineering Mechanics; Teknisk mekanik;

    Sammanfattning : Membrane structures are commonly used in many elds. The studies of thesestructures are of increasing interest. The two projects focus on the evaluations ofequilibrium states for uid-pressurized membranes under dierent loading conditions,and the corresponding instability behavior. LÄS MER

  4. 3. ON THE WAKE STRUCTURES OF FLOW AROUND DEFORMING AND VIBRATING BODIES

    Författare :Alper Cesur; Strömningsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Large Eddy Simulation; Fluid-Structure Interaction; Vortex-induced Vibrations;

    Sammanfattning : This thesis concerns the study of Fluid-Structure interaction phenomena among deforming and (non-deforming) vibrating objects under unsteady fluid fl ow exposures. This multi-physical phenomenon is widely encountered in real-life situations and therefore it is of significant importance to understand the underlying physics. LÄS MER

  5. 4. Interior Flow and Formation of Plain Orifice Sprays

    Författare :Zachary Falgout; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ballistic Imaging; Sprays; Fluid Mechanics; Mixture Formation;

    Sammanfattning : This thesis will summarize recent experimental observations of spray formation in highly atomizing plainorifce sprays, the kind commonly produced by fuel injectors in compression ignition internal combustionengines. Two special interactions will be addressed in detail: primary atomization under elevated ambientpressures and temperatures and orifce ow effects on primary atomization. LÄS MER

  7. 5. Reconstruction of a stationary flow from boundary data

    Författare :Tomas Johansson; Lars-Erik Andersson; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Cauchy problem; Generalized Stokes system; Ill-posed problems;

    Sammanfattning : We study a Cauchy problem arising in uid mechanics, involving the socalled stationary generalized Stokes system, where one should recover the ow from boundary measurements. The problem is ill-posed in the sense that the solution does not depend continuously on data.Two iterative procedures for solving this problem are proposed and investigated. LÄS MER
