LEIRO-GARRIDO, José-L.; BORRAJO-PEREZ, Rubén; GONZALEZ-BAYON, Juan-José  and  REYES-BEQUER, Nelson. Validation of a smooth configuration surface for compact heat exchangers using a numerical method. Ingeniería Mecánica [online]. 2014, vol.17, n.3, pp. 273-280. ISSN 1815-5944.

This work determines the thermo hydraulics behavior of smooth configuration surface for a compact heat exchanger by means of numerical simulation. The objective is to use the results as baseline for research in the enhancement of heat transfer and drag reduction, directed to reduce the energy consumption and diminish the environmental impact. The fin tube heat exchanger models described. The constraints used in the implementation of the equation solver are announced. The average heat transfer coefficient and pressure drop obtained from numerical simulation are compare to experimental results presented in literature for models with the same dimensions and configuration. A good agreement between numerical and experimental results is reached. Local mechanisms responsible for the heat transfer and pressure drop are detailed. The study is conducted inside the laminar regime for frontal velocities ranging between 0.5 and 6 m/s.

Keywords : compact heat exchanger; heat transfer coefficient; numerical simulation; pressure drop.
