A role of the heat and work uncompensatedtransformations in the balance of entropy and theturbomachinery efficiency
Abstrakt
In the paper we have presented a procedure of estimating a role of the uncompensated transformation of heat and work in ow of viscous and heat conducting uid. The procedure was introduced by Professor Romuald Puzyrewski and is essential in local, in time and space, balance of entropy. Furthermore this unique approach leads to redenition the eciency of uid-ow machinery in three-dimensional modeling using CFD (Computational Fluid Dynamics) methods. The study has shown that usage of the polytropic eciency, instead of the isentropic eciency, is more comfortable and seems to be more natural in CFD approach. Helpful is also correlation between those two eciency denitions with usage of proposed Pu number.
