Estimation of the spatial distribution of high heat flux pulse stimulations through infrared thermography
Source abstract
Abstract
Abstract A theoretical model obtained by using integral transforms is first presented. It is then used for the estimation of the heat flux distribution. As this problem is ill-conditioned, different techniques have been used for its identification, such as the estimation of heat flux spatial frequencies (harmonics by harmonics) or the estimation of the spatial frequencies in the Least Squares sense. These methods have been applied in the case of two different facilities, “TIC / TAC” at CEA-Cesta and the “LUMIX” bench at LEMTA, before being used for the high power electrons beam generator CESAR located in CEA-CESTA.
