PROBLEM TO BE SOLVED: To provide a flow analyzer with a resin viscosity calculation function for a development support device for performing simulation analysis of a behavior when a resin accompanying a plurality of curing reactions is injected to a mold to be molded, which has such a resin viscosity calculation function as to accurately calculate a change of the viscosity of the resin, and accordingly accurately grasp resin flow behavior in the mold and can find out an appropriate molding condition, a mold cavity shape, the number of injection ports, the arrangement and the like, on the side of the flow analysis.SOLUTION: A flow analyzer is configured to: measure a heat quantity of a resin, and measure a synthetic heat generation curve of a first heat generation curve exhibiting a curing reaction by polymerization and a second heat generation curve exhibiting a curing reaction by crystallization (S10); separate (calculate) the synthetic heat generation curve into the first and second heat generation curves, and calculate a degree α of cure of the resin, based on the first heat generation curve (S12); multiply initial viscosity of the resin by a value related to the calculated degree α of cure to calculate a viscosity ηp by polymerization of the resin (S16); and input the viscosity ηp to a development support device (S18).SELECTED DRAWING: Figure 2 |
