| Outline of Final Research Achievements |
The heat transport experimental setup was established and experiments were conducted. Furthermore, the volume-averaged transport parameters (which are permeability, inertia coefficient, interfacial heat transfer coefficient, longitudinal and transverse thermal dispersion) of periodic 3D Lattice Metal Frame structure for forced convection heat transfer are determined numerically by solving pore scale equations. One of the originality points of this study is to measure solid temperature inside of the sample by using Thermal Camera and special glass in the experiments.Both the fluid and solid temperature and also velocities in the channel are measured and compared with numerical studies and good agreement between them were observed. Based on this good agreement, numerical studies for different shapes of LMF has done and transport parameters are compared with each others. The study continues for the optimization of the shape of the Lattice Metal Frame.

| Academic Significance and Societal Importance of the Research Achievements |
Although metal foam is used for enhancement of heat transfer, the shape of the metal foam can not be optimized. This is study is a fundamental study for the use of Lattice Metal Frames which are good alternative for the metal foam. It can provide high heat transfer rate with minimum pressure drop.
