Mathematical Modeling of Heat Transfer Processes in a Wall with a Regular Pseudo-pore Structure

Conference paper
Part of the Lecture Notes in Electrical Engineering book series (LNEE, volume 549)


Porous and pseudo-porous structures are widely used in many areas of life, such as medicine, construction and, of course, the aerospace industry. The main advantages of this concept are its weight and economic efficiency, since the use of this method allows using much less material than using hollow structures to obtain similar force structures. However, it is difficult to implement such structures using traditional manufacturing techniques, such as stamping, casting or machining. This is only possible with the use of additive technologies. Filler technology is widely used in the aviation industry, especially in the manufacture of certain engine parts, with the exception of the combustion chamber. Thus, the implementation of porous or pseudo-porous structures using additive technologies can provide the production of structures with fundamentally new properties that can be used in GTE, for example, for more efficient cooling of combustion chambers. In this study, analysis of various spatial structures is performed using a segment with dimensions of 100 mm × 50 mm × 1 mm as an example. In terms of design both classical design methods and specialized software for additive technologies (Materialize Magics and Autodesk Netfabb). For design options in the Ansys CFX CFD package, the characteristics of the heat transfer process in the wall and in the surrounding space are defined. All designs are built with the possibility of their implementation on the existing equipment laser sintering of metal powders (layer deposition). The next stage of the work will be the verification of the calculated results carried out in a model experiment using SLA prototypes and a thermographic study of the thermal state of the wall.
