Two-orthogonal-view reconstruction algorithm based on maximum entropy theory is proposed. Multi-peaks asymmetrical flow fields can be well reconstructed by the proposed reconstruction algorithm according to two-orthogonal-views projection data. Additional prior information with axial symmetrical gene is combined into the new algorithm, the prior information can be calculated by the two-orthogonal-views projection data, and the effect of projection angel factor is analyzed. The numerical simulation results show that reconstructed results of multi-peaks asymmetrical flow fields obtained by the proposed algorithm are superior to the traditional alborithm, and the double-peak-cosine-Gauss simulated field root-mean-square error decreases 73%. Three-peak-random-Gauss simulated field root-mean-square error decreases 47%. So the proposed novel algorithm strongly shows superiority to reconstructing multi-peaks asymmetrical flow fields. Meanwhile only projection data two of orthogonal directions are needed so the experiment system is simplified.
