本文搭建了4.2 kW标准化的旋流燃烧机理实验台,通过调节配风构造了三种旋流强度(旋流数S=0、0.5和0.9)的燃烧工况,测量并比较了不同旋流数下的流场结构及温度特性。相比直流燃烧火焰,全旋流燃烧火焰=的长度缩短,径向展宽增大。基于OpenfOAM对各工况的数值模拟结果与试验测得的火焰形貌、回流区结构及温度分布特性吻合较好。利用拉格朗日方法追踪了直径40μm颗粒在旋流场中的运动轨迹,发现部分颗粒被回流区卷吸重新进入高温区。分析颗粒运动轨迹上的聚并核函数演化,发现其在高温回流区取值较大,在下游随着温度和湍流耗散率的降低而逐渐减小。本研究为煤粉旋流燃烧过程中的细颗粒物生成提供了前期的基础。

材料热处理学报 2004年第5期25卷 582-587页

作者： reinhold Schneider Klaus Sammt Roland Rabitsch Michael Haspel BOHLER Edelstahl GmbH Kapfenberg Austria

This paper gives a short introduction to the typical process route and material properties of these steels in comparison to standard martensitic corrosion-resistant steels. The typical response of these steels to various heat treatment parameters is shown and explained using the three grades M333, N360 and M340 (all made by Bohler Edelstahl GmbH) as examples, and the physical metallurgy of these steels and its consequences for practical heat treatment is explained. The correlation between tempering parameters and their effect on the toughness and corrosion properties is explained in particular detail, showing that these new steels not only offer far better property combinations under the usual heat treatment parameters than standard martensitic corrosion-resistant steels, but that they also open the door to extending heat treatment combinations and properties.

In this article, we analyse three related preconditioned steepest descent algorithms, which are partially popular in Hartree-fock and Kohn-Sham theory as well as invariant subspace computations, from the viewpoint of minimization of the corresponding functionals, constrained by orthogonality conditions. We exploit the geometry of the admissible manifold, i.e., the invariance with respect to unitary transformations, to reformulate the problem on the Grassmann manifold as the admissible set. We then prove asymptotical linear convergence of the algorithms under the condition that the Hessian of the corresponding Lagrangian is elliptic on the tangent space of the Grassmann manifold at the minimizer.
