PROBLEM TO BE SOLVED: To provide a fluid flow-rectification member of a structure in which the overheating is suppressed even when a high-temperature fluid passes through.SOLUTION: An outermost layer ceramic fiber layers 221 and 222 on an outer surface and/or inner surface of a supporting member in a fluid flow-rectification member 10A are constructed of a strand 21 which is oriented orthogonal in plan view with respect to a central axis CL, and in which a surface becomes wavy; thereby, the wavy shape of the outermost layer disturbs a flow of the fluid, causing a vortex in the surface; because of the presence of this vortex, even when a high-temperature fluid passes, a relatively low-temperature air layer is formed on the surface and is interposed between the fluid flow-rectification member 10A and the fluid, and overheating can be suppressed.SELECTED DRAWING: Figure 3
【課題】高温の流体が通過する場合にも過熱を抑制する構造の流体用整流部材を提供する。【解決手段】流体用整流部材１０Ａの支持材の外側面および／または内側面における最表層のセラミック繊維層２２１、２２２は、中心軸ＣＬに対して平面視で直交して配向しているストランド２１によって構成されており、表面は波状になる。このため、最表層の波状の形状が流体の流れを乱し、表面に渦流を生じさせる。この渦流が存在することで、高温の流体が通過する場合でも、相対的に低温の空気の層が表面に形成されて、流体用整流部材１０Ａと流体との間に介在するので、過熱を抑制することができる。【選択図】図３
