Abstract

In this paper, the effect of cooling rate of a cooling system on performance of a centrifuge machine has been studied experimentally. The cooling rate is increased by temperature variation and volumetric flow rate of the inlet water to the cooling system. The results showed that the effect of cooling rate on separative work unit (SWU), heads and tails separation factors i.e. α and β are negligible. Also, if the cooling rate is less than a minimum value, the heat produced by moving machine elements cannot be dissipated and some elements of machine may be destroyed.
