In this study, a practical numerical analysis has been developed in order to investigate the lubrication characteristics between a rolling piston and a crank of rotary compressors. This analysis is treated as a coupled problem of the momentum equations and the Reynolds equation of oil film. Using this analysis, the lubrication characteristics between the rolling piston and the crank for 2-cylin...

In this paper analytical study has been made to investigate a hybrid refrigerant consists of different refrigerants with mixing ratios and find out its effects on the performance cycle specify best that gives least environmental pollution. Firstly vapor compression refrigeration system analyzed several pure refrigerants( R11, R12, R13,R22,R23, R32, R41, R115, R116, R124, R125, R134a, R142a, R14...

The vapor compression cycle refrigeration machine is the type of that most widely used today, generally medium as a working fluid transfers heat from product being cooled to its environment synthetic refrigerant. called Refrigerant main in air conditioning systems absorb and convert it system. This then encourages countries world including Indonesia jointly carry out prevention improvement by m...

Regev and Vershik (Electronic J. Combinatorics 4 (1997), #R22) have obtained some properties of the set of hook lengths for certain skew Young diagrams, using asymptotic calculations of character degrees. They also conjectured a stronger form of one of their results. We give a simple inductive proof of this conjecture. Very recently, Regev and Zeilberger (Annals of Combinatorics, to appear) hav...
