Paper Title
PERFORMANCE EVALUATION OF COMPOUND MULTILAYER INSULATION (77K-300K)
Abstract
Multilayer insulation (MLI) using alternate layers of shield and spacer. In high vacuum MLI is the most effective Cryogenic Insulation. The Investigations are centered on the influence of the number of layers and layer density, with the cold boundary at the same temperature as liquid nitrogen. The paper Presented theoretical and experimental investigation of the heat transfer of different MLI with different vacuum chamber pressure. Liquid nitrogen boil of rate method is used to measure the heat transfer rate. The apparent thermal conductivity were calculated over a wide range of temperature (77k-300k) and pressure (10-6 mbar – 103mbar). The thermal performance of compound and Composite MLI is investigated. The temperature profile and heat transfer through the MLI were obtained as a function of level of vacuum and vice versa.
