An increase of turbine blade loading can reduce the numbers of blade and stage of gas turbines. However, an increase of blade loading makes the secondary flow much stronger because of the steep pitch-wise pressure gradient in the cascade passage, and

For the first time, a systematic experimental investigation on flow fields and losses of an ultra-highly loaded turbine cascade with bowed blades has been conducted. Flow patterns, secondary flow vortices and vectors, losses, and yaw angles at the do

A S ONE of the major measures to improve the aerodynamic performance of modern turbines, highly loaded blades (blades with a high-turning angle) have attracted much attention in the past two decades [1–7]. However, it is found that due to the high-

Due to the serious flow separations and centralized vortices, there are high secondary losses in highly loaded turbines. It is imperative to find measures to control the flow separation and vortices hence improve the turbine performance. This paper r

Since the end of the Cold War, Japan's strategic value to the United States has undergone a qualitative shift, leaving uncertainty about how much the US can be depended upon to complement Japan's defense capacity. North Korean, Chinese, and Russian a

The primary role of Japan's Self‐Defense Forces, says Atsumasa Yamamoto, is to safeguard the independence and liberty of Japan. He notes, however, that in the post‐Cold War world, the SDF must be prepared to play a supplemental role: to help Japa
