  The distribution of heat flux of the combustor is particularly important for the thermal protection system of scramjet.A new method is presented for calculating the average heat flux through the wall temperature including the thermal response model,convergence criteria and control algorithms.Then the axial and circumferential distribution of the average heat flux could be calculated by using the method and the temperature which is measured in the experiments of Mach 6 and different equivalence ratios.And the reason about the heterogeneous distribution of the heat flux is obtained through the distribution.In addition,the rule of the combustion heat release which is useful for guiding the combustion and the design of the thermal protection system is also obtained by analyzing the distribution.

随着国家政策和相关接入标准的出台,分散式风力发电逐渐成为了风电行业的一个新的发展方向。目前,已有分散式风电的示范项目投入运营。但是,由于配电网处于电网的末端,并且负荷的启停对配电网的频率造成了较大的冲击,导致了配电网的频率偏差较大,因此对接入配电网的分散式风电机组的频率适应性提出了更高的要求。本文针对以分散式接入到配电网的双馈风电机组的频率适应性,分别考虑了双馈感应发电机运行高速低频时和低速高频时
