Abstract

"SISTEMA PARA MEDIçãO DE PROPRIEDADES TéRMICAS DE FLUIDOS". A presente invenção se refere a um sistema, composto por componentes mecânicos, eletrónicos e por um programa de computador residente inerente ao sistema. O dito sistema para a medida de propriedades térmicas de fluidos se destina à medida de propriedades térmicas tais como difusividade e efusividade, e a partir desses valores, obter a condutividade e a capacidade térmica volumétrica de meios fluidos. Além do uso para a medida direta de propriedades térmicas, o referido sistema tem aplicação na constatação da qualidade ou de adulterações em combustíveis (octanagem e não conformidade), óleos combustíveis e lubrificantes, perfumes, alimentos, bebidas, além de funcionar como medidor de umidade e gases. Nestes casos, o que se deseja é a correlação entre a propriedade térmica medida, e o parâmetro de qualidade da substância analisada. A presente invenção não somente é passível de ser produzida pela industria, como pode ser utilizada em indústrias e em laboratórios.
