Abstract

Holographic interferometric tomography has been used to reconstruct the 3D temperature field around a single isothermal cube in an infinite medium, which is under ill- posed reconstruction conditions of restricted scanning and incomplete projection. A reconstruction algorithm, termed the variable grid method, has been employed to improve the reconstruction under the ill-posed conditions. The heat transfer results are presented in terms of the average Nusselt number and the face-average Nusselt numbers at the top, bottom, and side walls of the cube. Some heat transfer results are also compared with those previously reported. The study demonstrates that the interferometric technique is applicable to measurement of convective heat transfer of reasonably complex, 3D fluid flow.
