Numerical Simulation Of SPH On Heat Conduction

The smoothed particle hydrodynamics (SPH) numerical simulation method on heat conduction is studied from theory,program design and examples analysis in this paper. The main aspects of research works in this paper are as followes:Plenty of liteatures are investigated related to the SPH method,and the theoretical foundations are summed up systematically ,and a good understanding is obtained of the research progress on the SPH method and the development trend had ;A series of formulation the heat condution of SPH numerical simulation based on the Descartes coordinate system is deduced. A series of methods is adopted to different boundary conditions ; The computing program is established in the FORTRAN language of the heat condution of SPH numerical simulation based on the Descartes coordinate system;A series of heat conduction problem is simulated with the astablish computing program. The research results obtained indicate that the SPH numerical simulation method is reasonable and the program is reliable, and the superiority is displayed of the numerical simulation method of SPH.
