Abstract Additive manufacturing (AM) has an affinity with topology optimization to think of various designs complex structures. Hence, this paper aims optimize the design a lattice-structured heat sink, which can be manufactured by AM. The objectives are maximize thermal performance convective transfer in natural convection simulated computational fluid dynamics (CFD) and minimize material cost required for AM process at same time. lattice structure is represented as node/edge system via...

Abstract The elastocaloric effect denotes the ability of a material to release or absorb heat when is stretched and released respectively. This may be used design an alternative cooling device. work focuses on development device using natural rubber (NR) as material. It consists solid–solid exchange between cyclically two exchangers, respectively put in contact with it released. An experimental was designed tested order assess temperature span power ( PC ) achievable by NR based single stage...

We have developed a method to measure thermodiffusion and Fickian diffusion in transparent binary solutions. The measuring instrument consists of two orthogonally aligned phase-shifting interferometers coupled with single rotating polarizer. This high-resolution interferometer, initially isothermal coefficients liquid systems [J. F. Torres, A. Komiya, E. Shoji, J. Okajima, S. Maruyama, Opt. Lasers Eng. 50, 1287 (2012)], was modified transient concentration profiles solutions subject linear...
