Experimental Study of Integrated Vortex Board with Exergy Analyses

Abstract

The integrated vortex board was made up of many vortex chambers, it was the integration managed in individual vortex tube and its structure was more complicated. It could be regard as one and open ones mouth the system to study. In this paper, basing on the first and second law of thermodynamics, thermodynamics model was set up firstly , which was suitable for the exergy analyses of integrated vortex board energy separation, then the relationships of exergy efficiency and irreversibility were obtained. Combining with the experiment data , the exergy of the integrated vortex board was analyzed, in view of the effect of inlet pressure, cold mass, diameter of outlet orifice, length of hot tube, structure of entrance nozzle on energy separation effect and exergy efficiency. The dimension and operating condition of integrated vortex board could be optimized.
