Caracterização termofísica de polpas de bacuri
SUMMARY THERMOPHYSICAL CHARACTERIZATION OF BACURI PULP. Thermophysical properties, specific heat, density, thermal diffusivity and thermal conductivity of bacuri pulps at different concentrations were studied. The specific heat was determined by the mixture calorimeter method; the density was determined by the pycnometer; the thermal diffusivity was obtained by using the infinite cylinder method; the thermal conductivity was determined from the experimental results obtained for density, specific heat and thermal diffusivity. All the properties were also theoretically determined using proposals equations and regressions. Among the experimental results the specific heat varied from 3.616 to 2.986 kJ/kgoC; the density varied from 1,008.40 to 1,048.36 kg/m 3 ; the thermal diffusivity varied between 1.637x10-7 and 1.787x10-7 m2/s; the thermal conductivity varied from 0.50 to 0.64 W/moC. Except for the density, the value of all the properties decreased, whereas the concentration increased. The thermal conductivity was fitted
