Computational modeling of the Conjugated thermomechanical and aerogasdynamics processes for composite structures of high speed vehicles
IOP Conference Series: Materials Science and Engineering, 2019Co-Authors: Yu. I. Dimitrienko, Andrey Zakharov, M. KoryakovAbstract:A Conjugated Problem statement for aerodynamics and thermomechanics of heat-shielding structures from thermally decomposing polymer composite materials is proposed. It is based on the iterative solution of the three types of detached Problems: aerogasdynamics Problem for viscous heat-conducting flows, internal heat and mass transfer and thermoelasticity of shell constructions. An example of the numerical solution of the Conjugated Problem is given. It is shown that due to the high temperatures of the aerodynamic heating of the structure made of a polymer composite material there can appear a polymer phase thermodecomposition and intensive internal gas generation into the structure of the material.

Computational Modeling of Conjugated Aerodynamic and Thermomechanical Processes in Composite Structures of High-speed Aircraft
Applied Mathematical Sciences, 2015Co-Authors: Yu. I. Dimitrienko, M. Koryakov, Andrey ZakharovAbstract:A Conjugated Problem statement for aerogasdynamics, internal heatand-mass transfer and thermal strength of heat shield structures of hypersonic vehicles is formulated. A method for numerical solving of the Problem is suggested which is based on the iterative solution of the three types of detached Problems: a gasdynamics Problem for viscous heatconducting flows, internal heat-and-mass transfer and thermoelasticity of shell constructions. An example of the numerical solution of the Conjugated Problem is given. It is shown that due to the high temperatures of the aerodynamic heating of the structure made of a polymer composite material there can appear a polymer phase thermodecomposition and intensive internal gas generation into the structure of the material.

the analysis of the thermal structure Conjugated Problem of the percutaneous laser disc decompression
20th International Symposium on Transport Phenomena, 2013Co-Authors: Ipeng Chu, Kuochi LiuAbstract:This study is to discuss the variation of different surgical conditions while PLDD is processing. The multiphysics analysis algorithm is used to understand the temperature and stress distribution of the whole domain and heat transfer phenomena under the different kinds of laser heating rate and patients. In this study, the effect of thermal conductivity related about the patient’s age will be illustrated. In addition, the temperature profile is predicted as the heat transfer phenomena can be handled on the surgical process. In future, we expect that this result can be used to handle the PLDD in the pre-surgical simulation.

On the solvability of nonlocal boundary value Problem for the Helmholtz equation with the equality of flows at the part of the boundary and its Conjugated Problem
Integral Transforms and Special Functions, 2010Co-Authors: E. I. Moiseev, V. E. AmbartsumyanAbstract:The nonlocal boundary value Problem for the Helmholtz operator in the circular sector with the equality of flows on the radii and with the equality to null solution at one of the radius is considered. The Conjugated Problem is also considered. The uniqueness of the solution of these Problems is proved and the solution is built by the spectral method.
