Information × Registration Number 0209U001272, 0106U000786 , R & D reports Title Continuos media mechanics problem with moving and unstable boundaries of property distribution popup.stage_title Head Polyakov Mykola Viktorovich, Registration Date 27-01-2009 Organization Oles Honchar Dnipropetrovsk national university popup.description2 Object of investigation is hydrodynamic and thermal processes in the continuos media, non-linear problems of fluid mechanic with moving boundaries, shock and detonation waves, tangential velocity gaps, boundary integral equations of potential theory, numerical algorithms of boundary element method. Aim of investigation is development of universal, reliable and high accurate approaches for the calculation of mechanical, physical and chemical processes in the continuos media, when the domain boundary can be movable, undefined or unstable. Investigation methods: mathemetical modellig methods, methods of potential theory. Investigation results are development of new high accurate algorithms of boundary element method; generalisation of boundary element method and adaptation of proposed algorithms for boundary-value problems with moving boundary; new mathematical models and numerical algorithms of structured and unstructured discretization of complicated movable domains by sets of unstable topology; new mathematical models of hydrodynamic and heat and mass transfer processes in domains with changeable geometry, new investigation method of unstable boundary motion on the base of comparison analyses of results of application of different numerical methods. The field of the investigation application is the shipbuilding, machinebuilding, material science and space explorations. Product Description popup.authors popup.nrat_date 2020-04-02 Close
