Indirect measurement of the heat conductivity and specific heat coefficients of homogeneous fluid

Abstract

The coefficients of heat conductivityk and of specific heatc p have been determined as parameters of a system of differential equations of balance and boundary conditions. The values of the coefficientsk andc p are obtained by solving the inverse convection problem. The inverse convection problem includes a system of differential equations resulting from the mass, momentum and energy balances, the boundary conditions and an additional condition consisting of satisfying the postulate of the minimum squares of differences of the temperatures computed numerically and those measured at given points in the measurement tube.
