Abstract

The research consists of the automation of a rotating test tunnel, through an interactive platform, with heating systems by means of electrical resistances coupled to test pieces in different geometric configurations. The working fluid is air, applying a flow controlled by a fan through the mobile duct, at different angles of inclination. Thermodynamic variables are monitored by Arduino hardware that allows information processing. The signals are sent and displayed using the platform integrated by the LabView control and design software; Within the programming with the application, the coefficients of natural and forced convection obtained experimentally, showed a deviation of less than 5% compared to the theoretical data in different conditions of heat transfer by this mechanism, taking into account that the temperature sensors have a sensitivity of 0.25 °C, giving the equipment reliability and confidence of up to 95% accuracy, with air speed in the range of 1.5 to 2.4 m/s.
