The invention discloses a modeling method for an annular rotary single-tube flame tube, relates to the technical field of combustion chamber design, and aims to solve the problem that combustion characteristics of an annular combustion chamber cannot be simulated by using a low-cost single-tube combustion chamber test in the prior art. According to the technical key points, an annular flame tube is composed of N 1/N-period annular flame tubes with the same structure and combustion characteristics, and the process of modeling the 1/N-period annular flame tubes into a single-tube flame tube comprises the steps that for a front section, the contour line of the middle section of the front section rotates around the central axis of a circular port to form a bowl-shaped closed period, the front section of the single-tube flame tube is formed; for the rear section, the contraction angle is reduced according to the molded line of the front section of the single-tube flame tube, so that the contour line of the rear se
