Method & Evidence

AimTo develop and validate a numerical model for simulating heat transfer through a multi-layer protective clothing package, enabling the assessment of thermal performance.

MethodNumerical simulation and experimental validation

ProcedureA numerical model representing the macroscopic geometry of basalt fabric (plain weave) was developed, treating threads as porous materials. Thermal properties were determined using data from Alambeta device measurements of bare and aluminized basalt fabrics. The model was then used to simulate heat transfer through a protective package consisting of aluminized basalt fabric, wool clothing, and cotton underwear, and the results were compared with experimental measurements.
