Hidden defects affecting the interface in a composite slab are evaluated from thermal data collected on upper side of specimen. First we restrict problem to component object. Then investigate heat transfer through, inaccessible by means Thin Plate Approximation. Finally, Fast Fourier Transform is used filter data. In this way, obtain reliable reconstruction simulated flaws contact conductance c...

the density and viscosity values at t= (293.15 to 323.15) k for binary mixtures of nitromethane with 2-propanol, 2-butanol and 2-pentanol were measured over the entire composition range. from the experimental data, excess molar volumes, thermal expansion coefficients, excess thermal expansions, partial molar volumes at infinite dilution and deviations in viscosity were calculated. the results w...

In this study the thermal conductivity and the volumetric heat capacity of non-Newtonian fluids are investigated. These fluids find many applications in chemical, medical and food industries. They mostly have viscoelastic behavior and generally differ from Newtonian fluids. Two non-Newtonian fluids, solutions of xanthan and carboxy methyl cellulose in water with various concentrations have bee...

physical characteristics of different features in desert is a reflection of severe thermal and climatic conditions. in this paper, diurnal surface temperature patterns of important surface features in lut desert were studied and the relationship among different surfaces analyzed. diurnal trend in surface temperature of surface types, marl, dark sand, light sand, salt-affected soil, soul at 10 c...

Thermal hydraulics of nuclear reactor as a basis of reactor safety has a very important role in reactor design and control. The thermal-hydraulic analysis provides input data to the reactor-physics analysis, whereas the latter gives information about the distribution of heat sources, which is needed to perform the thermal-hydraulic analysis. In this study single heated channel model as a very f...

The thermal conductivity of superconducting MgB 2 was studied in both the superconducting and normal state region. The latter is almost equally determined by the electronic-and the lattice thermal conductivity. In the superconducting state, however, the lattice thermal conductivity is larger. The electronic thermal conductivity below T c was derived from the experimental data considering the Ba...
