N progress for the reverse cycle. Furthermore, a method was proposed to predict the indicated work from the positive Stirling cycles based on the reverse ones. By far the most critical situation with this process was to establish an linked model of the gas temperatures in the expansion/compression space. A mathematical model to predict the indicated power of the optimistic and reverseWheat2 Stirling cycles was proposed: -W = A( Tge2 -Tgc2 . The error involving the values of gc1 ge1 cool1 the model along with the experiment with He at 2.8 MPa was at the selection of -0.5.4 . These outcomes indicate that the model can give much helpful information for studying a Stirling engine and also a refrigerator simultaneously and will in all probability bring a sensible technique for forecasting a constructive cycle through a reverse one particular. 3-Chloro-5-hydroxybenzoic acid Cancer T-TBAuthor Contributions: S.W. and Gang Xiao contributed to all aspects of this perform; B.L. conducted the data analysis; S.W. and G.X. wrote the key manuscript text; M.N. gave some helpful comments and recommendations for this function.
