Abstract

The index of “blockage coefficient” was put forward to quantize the flow condition of marine cartridge filter intuitively and accurately, and theoretical analysis and experimental investigation on the relation among blockage coefficient, local resistance loss coefficient and Reynolds number were performed. Experimental results show that the change of filter’s local resistance loss coefficient is mainly decided by the change of blockage coefficient, and the calculating formula of blockage coefficient and local resistance loss coefficient are obtained according to experimental data at the same time.

Key words

marine cartridge filter / blockage coefficient / local resistance loss coefficient / variable-controlling method / data fitting
