HEAT TRANSFER ANALYSIS OF INSULATION MATERIALS WITH FLEXIBLE MULTILAYERS

摘要: A new flexible multilayer thermal insulation material is presented for applications at harsh environment as high 433 K or low 123 K. heat transfer model established and solved to study heat through the material, including radiation, solid gas transfer. Comparison between the experimental results theoretical prediction shows that feasible be applied in engineering. The temperature distribution of samples with 10, 15, 20, 25, 30 layers, respectively, a sample 10 layers are analyzed conditions (123 K) normal condition well. The analysis provides an active instruction optimal design such protective materials.
