In recent years, the fine-honeycomb consisted of very small cells has been developed. The pressure drop and turbulence reduction by fine-honeycomb are examined experimentally. Four kinds of fine honeycombs are used, and one kind of mesh screen is used for comparison. The results show that the pressure drop of the fine honeycomb is approximately proportional to the thickness of fine-honeycomb. The effects of the uniformization of mean velocity and the turbulence reduction can be established by using the fine-honeycomb. The turbulence reduction is comparable in both case of the fine-honeycomb and the mesh screen.
