| Outline of Annual Research Achievements |
For the experimental work: The experimental setup was designed and established. The temperature and velocity of air at the inlet and outlet, and temperatures at the heated surfaces were measured. The solid temperature in the solid region was measured by tomography method against time. For volume average equation, a commercial code is used to determine the volume average temperature and velocity in fluid and solid phases. The profiles of temperature and velocity at the the outlet and inlet of the regions and solid phase temperature at different points are compared with experimental results and good agreement was observed.For the pore scale study, the study was performed for 4 different lattice structures and the results for macroscopic transport parameters of them are compared.

Current Status of Research Progress
1: Research has progressed more than it was originally planned.
Reason
Now, the experimenatland numerical results are better and match each other. The pore scale results are also meaningful and provides good information for designers.
|
| Strategy for Future Research Activity |
The experiments will be done for different values of Re number. Those values will be comapred with the volume avergaed results. Furthermore it will support the pore scale results and finally hints for the proper stacture will be discovered.I will attend to international conferences in Japan and abroad for presenting of the obtained results.
|
| Causes of Carryover |
The experimental setup will be improved to obtain more accurate results, more sensitive devices with high resolution will be bought. We could not measure pressure difference in the last year, a new high sensitive pressure gauge will be bought for measuring pressure difference. Another Lattice Metal Frame will also be produced and tested to improve our theory. Based on the budget, buying a faster workstation for obtaining numerical results quickly and also buying a thermal camera is also thought.
