为了解决非完全数据条件下复杂流场的三维层析重建,结合计算流体力学(Computational fluid dynamics,CFD)、计算流动显示技术(Computational flow imaging,CFI)和光学层析技术(Optical computerized tomography,OCT),提出了应用于非完全数据流场重建的虚拟实验和真实实验相融合(即CFD,CFI与OCT融合)的三维层析。非对称双峰温度场实验结果表明,与完全数据重建结果相比,虚拟实验与真实实验相融合的三维层析的重建双峰误差小于5％。因此能够更好地实现非完全数据条件下流场的三维重建,极大地提高非完全数据条件下流场重建的真实性,较好地与实际结果相吻合,从而为解决有限角条件下的严重非完全数据流场的重建开拓了一条新途径。

The optical computerized tomography (OCT) of incomplete data for three-dimensional detection of complex flow field is urgent to be but still not be resolved. A new three-dimensional tomography with the fusion of virtual and real experiments is proposed, which combines the technology computational fluid dynamics (CFD), computational flow imaging (CFI), and OCT. The experimental results of double-peak temperature field indicate that, compared with the reconstructed results of full data, the error of unsymmetrical the double-peak reconstructed by the three-dimensional tomography with fusion of virtual and real experiments is less than 5%. So this new three-dimensional tomography can reconstruct the flow field of incomplete data satisfactorily, improve the reconstruction resolution greatly, and thus provides a brand-new way for the incomplete data reconstruction with limited viewing angle.
