3d Numerical Simulation of Fibers Arrangement Effects on Thermal Conductivity of Polymer Matrix Composite

This study investigated the effects of different arrangements of three-dimensional fibers on polymer matrix composite thermal conductivity under heat flux boundary conditions. the thermal lattice boltzmann based on the d3q7 (three dimensions and seven temperature vectors) method is utilized to illustrate the thermal conductivity in 7 cases of pmc with a different arrangement of 3d fibers. non-dimensional temperature fields, isothermals, nondimensional thermal conductivity coefficient, nondimensional mean, and local temperature in 7 cases of pmcs have been investigated. the nondimensional thermal conductivity coefficient in each pmc has been analyzed to predict optimal levels of factors affecting this simulation to maximize and minimize the heat transfer rate. the results signified that nondimensional temperature field in a pmc with the arrangement of a fiber, triplet, and triangular perpendicular to heat flux had a greater rate than a pmc with the arrangement of fibers along the way heat flux. also, the maximum and minimum of nondimensional thermal conductivity coefficient were in pmc with the arrangement of triplet fibers perpendicular to heat flux,  and triangular fibers along the way heat flux, respectively.
