Introduction

Katsuyuki Nakayama is a notable inventor based in Hyogo, Japan. He has made significant contributions to the field of fluid dynamics and nuclear reactor technology. With a total of 2 patents, his work has been recognized for its innovative approaches to complex engineering challenges.

Latest Patents

One of Nakayama's latest patents is an "Apparatus and method for identification of swirling flow." This invention includes a swirling flow identification apparatus that features an eigenequation calculation section and a swirl axis calculation section. The eigenequation calculation section calculates an eigenvalue based on velocity data of a fluid at a coordinate point. If the eigenvalue is a complex number, the swirl axis calculation section defines an imaginary part of the complex number as a swirl function. This allows for the identification of swirling flow even in the presence of other flows.

Another significant patent is related to the "Nuclear reactor internal structure." This invention aims to suppress the generation and promotion of object-downstream separating vortices. By doing so, it ensures that coolant flows uniformly in a reactor core, reducing pressure loss and stabilizing the flow of coolant. The design includes a lower connecting plate arranged in a lower plenum, which comprises a ring portion with an asymmetric outer peripheral portion relative to the flow direction.
