چکیده
Abstract This paper develops a robust framework for the multiscale design of three-dimensional lattices with macroscopically tailored thermal and thermo-structural characteristics. A approach is implemented where discrete evaluations small-scale lattice unit cell characteristics are converted to response surface models so that properties exist as continuous functions micro-parameters. The derived constitutes free material optimization in space manufacturable micro-architecture. individual member dimensions enabled by adjoint method explicit expressions property sensitivities. demonstrated solving problems, significantly extending previous work which focused on linear structural response. solution shows improved optimality compared SIMP methodology. demonstrates method’s capability attaining prescribed displacement temperature gradients.

Three-Dimensional Flow and Thermal Structures in Glass Melting
This paper presents a study of the flow and thermal structures in the molten glass bath of a typical glass melting furnace with a throat but without air bubblers or electric boosting. Different separate effects on the flow structure of the glass melt are simulated, but only the glass melt is considered. The net heat flux distribution is imposed at the combustion space/glass melt interface, and ...
متن کاملThree-dimensional Composite Lattice Structures Fabricated by Electrical Discharge Machining
We present a novel method for fabricating carbon fiber composite sandwich panels with lattice core construction by means of electrical discharge machining (EDM). First, flattop corrugated carbon fiber composite cores were fabricated by a hot press molding method. Then, two composite face sheets were bonded to each corrugated core to create precursor sandwich panels. These panels were transforme...
متن کاملThree-dimensional characteristic approach for incompressible thermo-flows and influence of artificial compressibility parameter
In this paper the characteristics of unsteady three-dimensional incompressible flows with heat transfer are obtained along with artificial compressibility of Chorin. At first, compatibility equations and pseudo characteristics for three-dimensional flows are derived from five governing equations (continuity equation, Momentum equations in three directions, and energy equation) and then results ...
