This paper presents a mathematical model for studying heat transfer in a spacecraft multi-layered thermal protection system, focusing on material properties and thickness optimization. The heat equation is solved using the immersed finite element method, which efficiently handles material discontinuities at layer interfaces. Simulations are conducted for a three-layer thermal protection system with materials such as carbon composites, ceramics, and insulating foams. Results show the impact of material selection and layer thickness on thermal performance, providing valuable insights for spacecraft design. The study demonstrates the effectiveness of the immersed finite element method for multi-material heat transfer problems in aerospace applications.

Mechanisms of Heat Transfer
Conduction, accounting for approximately 3% of body heat loss at rest, is the process of exchanging heat between molecules of two materials in direct contact. This can result in both heat loss and gain. For instance, when the body is submerged in water, which conducts heat 20 times more effectively than air, it can either lose or gain significant...
