Industrial heat exchangers evaluation using thermal design and optimization

4 shows heat transfer results as a function of Reynolds number for Strouhal numbers above and below 0.25, which accounts for the clear influence of the scraper frequency on

As it can be seen in these figures, in general terms the improvement obtained using ice slurry is higher for the lower pipe wall temperature, the lower mass flow rate, the higher

Criterion R3 accounts for the heat transfer augmentation obtained when a reciprocating scraper is inserted in a smooth tube, for equal heat transfer area and power consumption..

However, during the co-current semi-cycle, the flow configuration may present low levels of enhanced heat transfer, according to the pressure drop signal (Figure 4) and the heat

A characterization of the heat exchanger performance is necessary to assess the relation between heat transfer enhancement and augmentation of power consumption (pumping and

Fanning friction factor results in counter-current conditions present a twofold inter- est: in the frame of this work, the evolution of friction factor with Reynolds number and

CFD simulations for different Reynolds numbers provide a further insight into the relation of the flow structures with wall shear stress, and their role on the local heat

Abstract: Ice slurry is well known as a biphasic secondary refrigerant that presents several potential advantages compared to single phase secondary refrigerants. These
