Analysis of heat transfer between a coolant fluid and a plastic blowing matrix using the ANSYS CFD tool

Abstract:

This publication deals with the analysis of heat transfer between a coolant (water) and a plastic blowing matrix in order to improve the finishing process for the production of plastic containers. The inlet temperature and pressure value from the cooling line to the blowing matrix are optimal values for the cooling of the matrix. In a first stage, the data was taken from the working temperatures of the mold, the temperatures taken were inside the mold, outside and also the temperature of the plastic sleeve when it leaves the extruder, these temperatures were measured with the Ecom Ex MP4a equipment, which is a heat gun. Subsequently, the values of pressures and flow rates were observed, with which the cooling line to the mould worked in this case the pressure is 4 bar and a flow rate of 10 m/s, these values are very important to carry out the simulation since they are the edge conditions of the system. Finally, the matrix was modelled in CAD software, this case was SOLIDWORKS, and then the simulation was carried out in the ANSYS software and the CFX module, which allows the simulation of heat transfer between a liquid and a solid.
