Wernik J., Wolosz K., 2016, Thermal Analysis of the Finned Channel of Pneumatic Pulsator Using Numerical Simulations and Thermography, Chemical Engineering Transactions, 52, 271-276.
The research on heat conduction through the finned channel of pneumatic pulsator was discussed. Rectangular fins are located on the channel. 3-D model of the channel was created. The developed model of 3-D channel of an industrial pulsator has been imported into COMSOL Multiphysics. This program is the environment for modelling and solving scientific and engineering problems based on partial differential equations. As a result, the solution was obtained in the form of temperature distribution on finned channel of pneumatic pulsator and the temperature distribution of the air flowing over the pulsator. Numerical methods are subject to certain errors, hence it is essential to verify the results. Real object were subject to thermographic tests in order to verify the correctness of the numerical model. The FLIR SC7600 camera was used. Non-contact diagnostic method based on the observation of infrared radiation has enabled visualization, registration and interpretation of temperature distribution on the surface of the tested channel. The resulting thermal images were compared with the temperature distributions designated using a computer. The use of thermography in laboratory tests to validation numerical models is possible. Therefore, when designing new devices, both techniques can be used methodically.
