前言煤粉锅炉犁形燃烧器理论及使用计算机求解三维NaVier-Stokes方程,指出了犁形燃烧器的如下特点: 1.来流对所设计型线在来流方向上的作用分力随型线的延伸而均匀变化。 2.来流对所设计型线的法线方向上正压趋于零。 3.犁形驻涡发生器表面的流体平行于所设计的型线流动,由于能均匀导流,所以具有最小的局部阻力。 4.曲面上流体微团具有滚动性质。 5.曲面上流体微团的滚动速度随型线的延伸而均匀加速。 6.双犁形驻涡发生器在平行流体流经后,可在两侧涡尾产生“热流楔”及两对涡尖发散造成热力叠加。
Preface Pulverized coal boiler plow burner theory and the use of computer to solve the three-dimensional NaVier-Stokes equations, pointed out the plow burner has the following characteristics: 1. The incoming flow of the design line in the direction of the incoming flow force with the type line The extension of the uniform change. 2. Flow to the normal line of the design of the positive pressure tends to zero. 3. Plow-shaped vortex generator in the surface of the fluid flow parallel to the design of the line, due to uniform diversion, it has the smallest local resistance. 4. Fluid surface micelles with rolling properties. 5. Rolling speed of the fluid micro-clusters on the surface accelerates uniformly with the extension of the profile line. 6. Double plow-type vortex generator in the parallel flow through the fluid can be generated on both sides of the tail vortex “heat flow wedge” and the divergence of the two pairs of vortex caused by thermal superposition.
