METHOD AND SYSTEM FOR MANUFACTURING A HEAT EXCHANGER FOR SUPERCRITICAL PRESSURE FLUID

摘要

A method and a system for manufacturing a heat exchanger for supercritical pressure fluid are provided. The manufacturing method includes: obtaining boundary conditions of the heat exchanger, adjusting a preliminary framework of the heat exchanger, dividing each of fluid passages along a fluid flow direction and establishing a thermal equilibrium control model, constructing a machine heat transfer model in combination with a Gaussian regression process and a Cokriging method based on the thermal equilibrium control model, determining on-way thermal parameters about the working fluids flowing and transferring heat, determining a heat transfer area according to the on-way thermal parameters, and determining whether the heat transfer area meets a target heat transfer area. If the heat transfer area meets the target heat transfer area the heat exchanger is manufactured according to the preliminary framework of the heat exchanger. If the heat transfer area does not meet the target transfer area, the primary framework of the heat exchanger is readjusted until the heat transfer area meets the target heat transfer area.
