| Abstract: | The structure of heat transfer-unit of quench boiler was numerical simulated based on ANSYS, and the tube flow distribution law under uniform thermal load was obtained. According to the diameter and the position of auxiliary connecting pipe, six kinds of structures were presented and their flow distribution laws were investigated, and then the optimum structure was obtained. For the intake header and elliptical flat tube of the optimum one, the velocity field and pressure field distribution laws were studied, and concluded that the pressure and velocity distribution was more uniform than the original structure, and thereby, verified the correctness of the optimum structure. |
