Abstract
The present work aims to analyze the forced convection laminar of the water-lithium bromide mixture in the thermal entry region of a circular duct. Different concentrations of the water-lithium bromide mixture were used to verify the development of the thermal field. With the aid of the engineering equation solver (EES) it was possible to obtain the thermophysical properties of the studied fluid. The energy equation was solved by the generalized integral transformation technique (GITT), which combines the reliability and precision of the analytical techniques at a competitive computational cost, without neglecting the versatility of numerical methods. The results presented in the form of tables and graphs allow to analyze, for pre-defined mass flow rates, the influence that different concentrations of the fluid exert on the development of the temperature field.
