Numerically calculation of rotary regenerator effectiveness

In this study, the effectiveness of rotary regenerators, which are used for energy recovery in different fields, has been calculated numerically. Firstly, regenerator differential equations have been written using the first law of thermodynamics. Temperature distribution in the regenerator has been calculated by solving simultaneously two differential equations for fluid and wall temperatures. A finite difference numerical method has been used for solving the differential equations. The effectiveness of the regenerator has been calculated from the temperature distributions. Results for the temperature distribution in the literature have been compared with the results calculated from simplified regenerator differential equations. It has been found that there is no significant difference in between these results. Finally, the influence of physical and thermal non-dimensional parameters on the regenerator effectiveness has been investigated and the results have been illustrated by graphics and tables.
