冷坩埚电磁连铸弯月面形状的数值模拟

电磁连铸中弯月面与磁场耦合作用，磁场约束弯月面成一定的形状。基于磁流体力学理论，导出以感应电流为末知量的冷坩埚电磁连铸的弯月面与磁场耦合的数学模型，并采用等参变换使连续曲面近似弯月面。在与实验结果对照的基础上，计算了感应器电流强度磁场频率、感应器位置以及冷坩埚的分片数等对弯月面形状的影响及变化趋势。

Integration property of a wedge-elliptic cone waverider with scramjet engine

The hypersonic waverider forebody is designed in this paper. For the present waverider, the undersurface is carved out as a stream surface of a hypersonic inviscid flow field around wedge-elliptic cone, and the upper surface is assumed to be a freestream surface. A finite-volume code is used to generate the three-dimensional flow field. The leading edge is determined by satisfying the condition that the lip is situated at the intersection line of shocks.
