No. of bitstreams: 1 149235.pdf: 754888 bytes, checksum: 14279035e861c8bc6cbe7bb71f100870 (MD5) Previous issue date: 1978-11 / CNPq / Desenvolve-se um modelo teórico para estudar a temperatura superficial transiente em chapas expostas à radiação eletromagnética. As influências das propriedades físicas, geométricas e das características espectrais superficiais da chapa são analisadas para estabelecer o tempo de resposta da temperatura superficial. Os resultados analíticos são comparados satisfatoriamente aos resultados experimentais obtidos em uma câmara especialmente construída para a absorção de energia solar. / Theoretical diffusive model is developed in order to determine the transient surface temperature on plates exposed to eletromagnetic radiation. The plates' surface temperature response time is analised by means at its physical, geometrical and emissive spectral properties. The analytical results are shown to accurately represent the experimental data that was obtained in a specially built solar energy absorving chamber.
