A moving tube bundle with attached baffles is used as an agitator and heat exchanger in certain types of crystallizers. It consists of two parts symmetrically positioned relative to the crystallizer axis. In each part there is a staggered arrangement of tubes in four rows, each of them containing six or seven tubes. To restrict the flow in regions where there are no tubes, three baffles are applied: the central placed in the middle of the tube bundle and two side baffles placed close to the walls of the vessel in which the tube bundle is moving. The value of Reynolds number calculated on the basis of tube diameter is between 0.01 and 1, and therefore laminar flow model is adopted. Heat transfer between fluid and tubes is not considered in this study. The values of hydraulic drag acquired from numerical simulations are compared with those characterising flows across a stationary tube bundle as reported in the literature.
