Multi-layer insulation modeling in Simcenter 3D Thermal

This article shows how to model multi-layer insulation in different ways. Multi-layer insulation (MLI) is a type of thermal insulation commonly used in spacecraft and other applications where it is necessary to maintain a stable temperature within a structure.

Details

This article discusses various approaches to modeling MLI, such as explicit MLI modeling, two-layer shells modeling, multi-layer shell modeling, and modeling using effective thermo-optical properties. The document outlines the pros and cons of each modeling approach, provides temperature range results for MLI and facesheets, and offers guidance on visualization and post-processing considerations.
