Abstract
In this paper, a new technique is shown to design crease patterns of meandering tubes by conformal transformation used for a flow with a source in fluid dynamics. It enables to design flat-foldable structures, which can be folded up onto plane and deployed in space at will, systematically by controlling the minimum number of design parameters, with fold lines regularly placed. The structure obtained by the proposed method consists of front and back patterns and is flat-foldable along two different axes. It is a simple method effectively utilizing the characteristics of conformal transformation that easily controls angles between fold lines.
